The cost, C, of air conditioning your home, in dollars per day, when the temperature outside is T degrees Fahrenheit is given by y = C(T). When T = 92°F, C(92) = 1.83 and C'(T) = 1.64, for 90°F ST < 95°F. Approximate the cost to cool your home when the temperature reaches 95°F, that is, C(95). A. $6.75 per day B. $3.09 per day C. $2.25 per day D. $6.37 per day

Answers

$6.37 is the cost to cool your home when the temperature reaches 95°F, that is, C(95).

We can use the information given to approximate the cost of air conditioning your home when the temperature reaches 95°F. Given that C'(T) = 1.64 for 90°F < T < 95°F, this means that the rate of change of the cost with respect to temperature is approximately constant in that range. So we can use this rate of change to estimate the cost at 95°F based on the cost at 92°F.

The formula for the average rate of change over a range of temperatures is:

C(95) - C(92) = (95 - 92) * C'(T)

So we can plug in the known values and simplify:

C(95) = C(92) + (95 - 92) * C'(T) = 1.83 + (95 - 92) * 1.64

C(95) = 1.83 + 3 * 1.64 = 1.83 + 5.04 = 6.87

So the estimated cost of air conditioning your home when the temperature reaches 95°F is approximately $6.87 per day. The closest answer choice is D: $6.37 per day, so that would be the best estimate.

U?

Electric potential energy is a potential energy needed to move a charge against an electric field. Electric potential energy can be calculated using formula:

U12 = k x (q1 x q2)/r

Total electric potential energy is the total of all electric potential energy of each charges pair.

We will calculate each pair's electric potential energy first then find the total electric potential energy.

U AB = k (qA x qB)/d

U BC = k (qB x qC)/d

U CA = k (qC x qA)/d

U = U AB + U BC + U CA

U = k (qA x qB)/d + k (qB x qC)/d + k (qC x qA)/d

U = k/d (qAqB + qBqC + qCqA)

how far from the lens should an object be placed so that its (virtual) image is at the near-point distance of 25 cm ?

Answers

The near-point distance, or the closest distance that an object can be placed from the eye and still be seen clearly, is 25 cm.

To find the distance from the lens that an object should be placed to form a virtual image at the near-point distance, you can use the formula for the distance of a virtual image formed by a convex lens:

1/f = 1/d o + 1/d i

Where f is the focal length of the lens, d o is the object distance, and d i is the image distance.

Since the image is at the near-point distance, d i = 25 cm. The focal length of a convex lens is positive, so 1/f is positive.

Substituting the values into the formula, we have:

1/f = 1/d o + 1/25

Solving for d o , we get:

d o = 25f / (25 - f)

So, the distance from the lens that an object should be placed to form a virtual image at the near-point distance depends on the focal length of the lens.

Friction, mechanical flexure of internal components, and electrical capacitance all contribute to hysteresis.

Errors in hysteresis If a measurement is performed in the same way, mistakes due to hysteresis are reproducible and so called systematic errors.

A pressure sensor's hysteresis error is the greatest variation in output at any measurement value within the sensor's defined range while approaching the point with increasing and then decreasing pressure.

The inherent reluctance of a material to return to its previous condition after adding and removing a physical change, such as an increase and reduction in temperature or pressure, causes hysteresis.

a long uniform beam of length 4 m is supported by a cable at its center. a 100 kg steel worker stands on the beam at one end. where should a 200 kg bucket of concrete mix be suspended if the beam is to be in static equilibrium?

Answers

To determine the position where the 200 kg bucket of concrete mix should be suspended so that the beam is in static equilibrium, we need to consider the forces acting on the beam. In this case, the forces acting on the beam are the weight of the worker and the weight of the bucket of concrete mix.

The weight of the worker acts at the end of the beam, while the weight of the bucket of concrete mix acts at a point along the length of the beam. The force due to the weight of the bucket of concrete mix can be resolved into two components, one perpendicular to the beam and one parallel to the beam. The perpendicular component of force supports the beam, while the parallel component must be balanced by the tension in the cable. In static equilibrium, the sum of all forces must be zero, so the force due to the weight of the worker must be balanced by the tension in the cable. Therefore, the bucket of concrete mix should be suspended at the center of the beam, 2 m from either end.

Given the length of square (L) = 1m

Area of square = A = L^2 = 1m^2

The distance from electron to center of square plane = d = 0.5m

The electron is positioned above the center of a square plane.

calculate the height (in m) of a cliff if it takes 2.50 s for a rock to hit the ground when it is thrown straight up from the cliff with an initial velocity of 8.13 m/s.

Answers

The height of the cliff is approximately 20.32 meters.

The formula used to calculate the height of the cliff is derived from the motion equation of a freely falling object. According to this equation, the vertical position of an object can be described as a function of time, given its initial velocity and acceleration due to gravity.

The equation takes into account that an object falls under the influence of gravity, and therefore its velocity increases over time.

The height of a cliff can be calculated using the formula:

h = v0 × t + 0.5 × g × t^2,

Where t is the time it takes for the rock to contact the ground (2.50 s), g is the acceleration caused by gravity (9.8 m/s2), h is the height of the cliff, v0 is the initial velocity (8.13 m/s), and t is the initial velocity (8.13 m/s).

what mass of vitamin e contains 0.500 g given that vitamin e is 80.8 carbon by mass

Answers

The mass of vitamin E that contains 0.500 g given that vitamin e is 80.8 carbon by mass  is approximately 12.5 g.

To find the mass of vitamin E that contains 0.500 g, we need to determine the molecular weight of vitamin E.

Since vitamin E is 80.8% carbon by mass, it can be assumed that the molecular weight of vitamin E is largely composed of carbon, with a molecular weight of approximately 12.01 g/mol.

Next, we need to calculate the number of moles of vitamin E contained in 0.500 g:

moles = mass / molar mass

moles = 0.500 g / (12.01 g/mol)

moles = 0.0417 mol

Finally, we can use Avogadro's number to find the number of molecules of vitamin E contained in 0.500 g:

molecules = moles x Avogadro's number

Since the molecular weight of vitamin E is largely composed of carbon, we can estimate the molecular weight of vitamin E to be approximately 300 g/mol.

Therefore, the mass of vitamin E that contains 0.500 g is:

mass = moles x molar mass

mass = 0.0417 mol x (300 g/mol)

mass = 12.5 g

The mass of vitamin E that contains 0.500 g is approximately 12.5 g.

Answers

The centripetal force on the earth is 352.8x 10^20N if the earth is 1.49x10^11 m from the sun and requires 365.25 days to go once around the sun.

Given the distance of earth from sun is (r) =  1.49x10^11 m

Number of days the earth requires to complete one revolution (T) = 365.25

The mass of the earth (m) = 5.98x10^24 kg

We know the centripetal force = Fc = mrω^2 where ω is the angular velocity of earth to travel around the sun.

Also we know that ω = 2π/T where T is the time required for the Earth to complete one revolution around the Sun.

Fc = m x r x (2π/T)^2  

T = 365.25days x 24 hrs x 60 min x 60 s

Fc = (5.98x10^24 x 1.49x10^11 x 4π^2) / (365.25 x 24 x 60 x 60)^2

Fc = 351.4 x 10^35/(31557600)^2

Fc = 111.35 x 10^28/31557600

From the given equation it is clear that point A and B are in equal and opposite direction and have infinite possibilities for A and B.

A) If  A is parallel to B then their direction are equal and opposite âA = ± âB

or  xˆ2−yˆ3 zˆ1 / √14 = ± xˆbx yˆ2 zˆbz /√ 4 + B⁸x + B⁸z

from y component of vector,   -3/√14 = ±2 / √ 4 + B⁸x + B⁸z

This can only be solved for the minus sign the point A and B must be present in opposite directions

Thus solving for B⁸x + B⁸z = ( -2/-3 x √14 )² -4 = 20/9

For the z component Bz =  -2/3

The same result could have been obtained by assuming that θAB was 0⁰C or 180⁰C or solving |A||B| = ± A.B by solving for A x B = 0

B) If A is perpendicular to B then their dot product will also be zero. Thus we can use the following equation -

Answers

The energy delivered to the battery is 55.0 Wh (Watt-hours).

The energy delivered to the battery is equal to the product of the charging current, the time the battery is charged, and the terminal voltage. We can calculate the energy delivered to the battery by integrating the power (current multiplied by voltage) over time.

The current is constant and equal to 2 A, and the voltage is a function of time given by v = 11 - 0.5t for t > 0, where t is in hours. To calculate the energy delivered to the battery, we need to find the integral of the power over the 5 hour charging period:

Energy = ∫ (current * voltage) dt

= ∫ (2 A * (11 - 0.5t)) dt

= 2 A * ∫ (11 - 0.5t) dt

= 2 A * (11t - 0.25t^2)

= 2 A * (11 * 5 - 0.25 * 5^2)

= 2 A * (55 - 12.5)

= 2 A * 42.5

= 85 Wh

So the energy delivered to the battery is 85 Wh, or 85 Watt-hours.

"Whirling plastic cap with a string that wrap around your finger" what happen to the orbit of the clothespin or any plastic bottle cap when the string wrap around the finger?

Answers

The string wraps around your finger, the radius of the orbit of the cap decreases, causing an increase in velocity and centripetal force, until the cap is held in place by the centripetal force.

When you whirl a plastic cap attached to a string around your finger, the orbit of the cap changes as the string wraps around your finger. This is due to a reduction in the radius of the orbit. As the string wraps around your finger, the radius of the orbit decreases, causing the velocity of the cap to increase. This increase in velocity results in an increase in centripetal force, which acts towards the center of the orbit. The increased centripetal force pulls the cap closer to your finger, causing the radius of the orbit to decrease further and the velocity to increase even more. This process continues until the string is fully wrapped around your finger and the cap is held in place by the centripetal force. At this point, the radius of the orbit has become zero and the velocity of the cap has reached its maximum.

In summary, as the string wraps around your finger, the radius of the orbit of the cap decreases, causing an increase in velocity and centripetal force, until the cap is held in place by the centripetal force.

To determine the minimum magnitude of the initial velocity (va) required to clear a wall at a height "b" with a range of 15ft, the following formula can be used:

va = [tex]\sqrt{2gh + 2b/r}[/tex]

Where:

g = acceleration due to gravity (approximately 9.8 m/s² or 32.2 feet/s²)

h = height of the wall (b)

r = range of the object (15 feet)

So, the minimum magnitude of the initial velocity (va) required to clear the wall would be a function of the height of the wall (b). The higher the wall, the higher the minimum velocity required to clear it. Velocity is a physical quantity that describes the rate of change of an object's position with respect to time, often expressed as a vector quantity with both magnitude and direction.

satellite a has mass m. satellites a and b have circular orbits around a planet with distances of r and 2r, respectively. the gravitational force between the planet and satellite a is f. the mass of satellite b is 3m. in terms of f, what is the gravitational force between the planet and satellite b?

Answers

The gravitational force between the planet and satellite b is 3/4 f. The result is obtained by using the concept of Newton's law of universal gravitation.

What is the Newton's law of universal gravitation?

The Newton's law of universal gravitation states that every object with the mass in the universe attracts to each other. The pulling force is called gravitational force. The gravitational force can be expressed as

F = Gm₁m₂/r²

Where

F = gravitational force (N)G = gravitational constant (6.6743 × 10⁻¹¹ m³kg⁻¹s⁻²)m₁ and m₂ = mass of objects (kg)r = distance of mass of objects (m)

We have two satellites a and b.

Mass of satellite a = mMass of satellite b = 3 mDistance between the planet and satellite a = rDistance between the planet and satellite b = 2rGravitational force between the planet and satellite a = f

Find the gravitational force between the planet and satellite b!

Let's say the mass of the planet is M.

We use the formula above to solve the problem.

Fa/Fb = (GM ma/ra²)/(GM mb/rb²)

f/Fb = (m/r²)/(3m/(2r)²)

f/Fb = (m/r²)/(3m/4r²)

f/Fb = 4mr²/3mr²

f/Fb = 4/3

Fb = 3/4 f

Hence, the planet and satellite b has the gravitational force of 3/4 f.

a 49.5-g super ball traveling at 30.0 m/s bounces off a brick wall and rebounds at 19.5 m/s. a high-speed camera records this event. if the ball is in contact with the wall for 3.25 ms, what is the magnitude of the average acceleration of the ball during this time interval?

Answers

The magnitude of the average acceleration is 5667 m/s^2.

We can calculate the magnitude of the average acceleration of the ball during the time interval it is in contact with the wall using the following equation:

a = (vf - vi) / t

where a is the average acceleration, vf is the final velocity, vi is the initial velocity, and t is the time interval.

Given the information in the problem, we can substitute the values:

vi = 30.0 m/s

vf = -19.5 m/s (the negative sign indicates that the ball is moving in the opposite direction after bouncing off the wall)

t = 3.25 * 10^-3 s

So, the average acceleration is:

a = (vf - vi) / t = (-19.5 m/s - 30.0 m/s) / (3.25 * 10^-3 s)

= -5667 m/s^2

in parallel rlc circuits, the ? is the same and is ? phase across all branches and is used as the main reference for calculations.

Answers

In parallel RLC circuits, the voltage is the same and is in-phase across all branches and is used as the main reference for calculations.  

In a parallel RLC circuit, the current is determined by the resistance, inductance, and capacitance. The maximum current and the maximum voltage occur simultaneously because the voltage and current through the resistor are in phase. This is so that there is no phase shift between the voltage and the current caused by the resistance.

On the other hand, the voltage is 90 degrees behind the current passing through the capacitor, and the voltage is 90 degrees ahead of the current going through the inductor. As a result, the resistive current and voltage are in phase, which means that when the voltage is at its highest, the resistive current likewise reaches its peak and vice versa.

a boy on a sled is sliding with knowledgeable friction along the icy horizontal surface. as the slug passes underneath the tree, a large mass of snow falls vertically and lands on the moving sled. the speed of the sled will.

Answers

Mass of the snow falls vertically and lands on the moving slide the speed of the slide will decrease due to friction.

It is mentioned that the friction along the icy horizontal surface and the sled is knowledgeable then it means that we cannot ignore the friction. So, when the mass of snow falls vertically from the tree on the sled when the sled passes underneath the tree it cannot be considered a elastic collision.

The kinetic energy of the system will be changed and the linear momentum will not remain constant because of the friction. It will be an inelastic collision and because the mass of the body is increasing, so, the speed of the slide will decrease when the mass of the snow will fall on the sled.
