Consider S:M (i.e. surface area to mass ratio) of an object. What happens to the ratio when the density of an object decreases while the surface area and volume remain the same?Group of answer choices:it increasesthe outcome cannot be determinedit depends on the nature of the material in the objectit decreasesit remains the same

Answers

Answer 1

The ratio of surface area to mass when the density of an object decreases while the surface area and volume remain the same, increases. The correct option is A.

An object's surface area and volume don't change, but its density does. The formula for density

ρ = m ÷ V

V = m ÷ ρ

m = mass (kg)

V = volume (m³)

ρ = the density (kg/m³)

The density decreases

ρ₁ > ρ₂

The surface area remains the same

A₁ = A₂

The volume remains the same

V₁ = V₂

V₁ = V₂

m₁ ÷ ρ₁  = m₂ ÷ ρ₂

m₂ × ρ₁ = m₁ × ρ₂

m₂ = (m₁ × ρ₂) ÷ ρ₁

ρ₁ > ρ₂

m₂ < m₁

The density decreases, and the mass also decreases.

The quantity of surface area per unit mass of an object is known as the surface area to mass ratio.

S:M = A ÷ m

At initial (S:M)₁ = A₁ ÷ m₁

At final (S:M)₂ = A₂ ÷ m₂

A₁ = A₂

m₂ < m₁

(S:M)₂ > (S:M)₁

Thus, the surface area to mass ratio will increase.

In one hour, 500x10^3 ft-lbr of work is done. What is the average power in kilowatts? Please answer these nroblems showing each sten in how to solve them

Answers

In one hour, 500x10^3 ft-lbr of work is done. 0.189 kW is the average power in kilowatts.

To find the average power in kilowatts when 500,000 ft-lbf of work is done in one hour, we'll first convert the work from foot-pounds to joules and then use that value to find the average power in kilowatts.

= 1 ft-lb

= 1.356 J

500,000 ft-lbf of work is equivalent to:-

= 500,000 ft-lbf x 1.356 J/ft-lb

= 678,000 J

Now, we'll use this value to find the average power in kilowatts:

= (work,J) ÷ (time,s)

= (average power in watts)

= 1 hr = 3600 sec,

= 678,000 J / 3600 seconds

= 189 W

Finally, we'll convert the average power in watts to kilowatts:

= (average power in W) / 1000

= (average power in kW)

= 189 W / 1000

= 0.189 kW

Hence, the average power in kilowatts when 500,000 ft-lbf of work is done in one hour is 0.189 kW.

A 77 g piece of ice at 0° C is placed in a beaker containing 545 g of water at 82° C. Assuming all the ice melts and disregarding the beaker, what is the final temperature of the mixture

Answers

Water contains almost one thousand times more matter than the same volume of air would ... The density of sodium metal at 0oC is 0.968g/cm3 , and 968kg/m3 .

what is the final temperature of the mixture?

If a mixture is having the same substance of the same mass then the mean of two temperatures is said to be the final temperature.

Calculate the final temperature of the water mixture using the equation T(final) = (m1_T1 + m2_T2) / (m1 + m2), where m1 and m2 are the weights of the water in the first and second containers, T1 is the temperature of the water in the first container and T2 is the temperature of the water in the second container.

The thermal energy of the warm water is not enough to melt all of the ice (only 93% of it), so the final temperature of the ice/water mixture will be 0ºC.

Add the change in temperature to your substance's original temperature to find its final heat. For example, if your water was initially at 24 degrees Celsius, its final temperature would be: 24 + 6, or 30 degrees Celsius.

f the spring constant is 200 n/m and applied force is -50 n, how much will the spring be stretched or displaced?

Answers

The spring will be stretched or displaced by -0.25 m. A negative displacement indicates that the spring is being compressed rather than stretched.

The amount of displacement, x, of a spring can be calculated using the equation:

x = F / k

where k is the spring constant and F is the applied force. In this case, the applied force is -50 N and the spring constant is 200 N/m. Plugging in the values, we get:

x = -50 N / 200 N/m = -0.25 m

The equation used to calculate the displacement of a spring is based on Hooke's Law, which states that the force required to stretch or compress a spring is proportional to the amount of displacement.

The proportionality constant, k, is called the spring constant, and it is unique to each spring and determines the stiffness of the spring. The higher the spring constant, the more force is required to produce a given amount of displacement.

describe the processes occurring in a nebula and explain why rocky planets are formed closer to the center of the solar system.

Answers

The processes occurring in a nebula include gravitational collapse, fragmentation, and accretion. Rocky planets, such as Earth, are formed closer to the center of the solar system because the temperature in the inner regions is high.

A nebula is a cloud of gas and dust in space where stars and planets are formed.

Gravitational collapse refers to the contraction of a cloud of gas and dust under its own gravity, which causes the material to become denser and hotter. This process leads to the formation of a dense core, known as a protostar.

Rocky planets, such as Earth, are formed closer to the center of the solar system because the temperature in the inner regions is higher, allowing the metals and silicates that make up rocky planets to condense and form solid bodies. In contrast, the outer regions are cooler and dominated by lighter elements, such as hydrogen and helium, which form gas giants like Jupiter. This is why the inner region of the solar system is dominated by rocky planets and the outer region by gas giants.

Answers

The mass of air is 58.110kg for a tank containing 2 m³ of air at -93°C and a gauge pressure of 1.4 MPa.

The ideal gas law equation is given below:

PV = nRT

where P is the absolute pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the absolute temperature.

Given: the volume of the tank, V = 2 m³

temperature of the air in the tank, T = -93°C

T = 273 - 93 K

T = 180K

Gauge pressure, P1 =  1.4 MPa.

Atmospheric pressure, P2 =  1 atm

1 atm =  101.325 kPa

P2 = 0.101 MPa

total pressure P = P1 + P2

P =  1.4 +  0.101

P = 1.501 MPa

Using the ideal gas equation,

PV = nRT

n = PV/RT

n =  1.501 MPa × 2 / 8.314 × 180

n = 2005.9 mol

mass of air = n × molar mass of air

mass of air = 2005.9 ×  28.97 g/mol

6. A thread holds two carts together on a frictionless surface. A spring is compressed between the two carts. After the thread between the two carts is cut the cart on the left with a mass of 1.5 kg moves away with a velocity of 27 cm/s. What is the velocity of the cart on the right that has a mass of 4.5 kg?

Answers

Answer: -9 cm/s

Explanation: The velocity of the right cart can be determined using the conservation of momentum principle. According to this principle, the total momentum of the system before the collision is equal to the total momentum after the collision.

The total momentum before the collision is 0, since the carts are initially at rest.

After the thread is cut, the total momentum of the system is given by:

m1 * v1 + m2 * v2 = 0

where m1 is the mass of the left cart, m2 is the mass of the right cart, and v1 and v2 are their respective velocities after the collision.

Substituting the given values, we have:

1.5 * 27 + m2 * v2 = 0

Solving for v2, we get:

v2 = -27 * 1.5 / 4.5 = -9 cm/s

Therefore, the velocity of the right cart after the collision is -9 cm/s.

Using the Clausius-Clapeyron equation, at 30°C, the vapor pressure of SiCl4 was found to be 205.4 mmHg.

The Clausius-Clapeyron equation can be used to describe the effect of temperature on the vapor pressure of a volatile compound. The heat of vaporization must be known in order to use the Clausius-Clapeyron equation. The Clausius-Clapeyron equation is shown in the attached picture.

According to question:-

T1 = 5.4 ∘c = 278.55 K

P1 = 100 mmHg

T2 = 30.0 ∘c = 303 K

δHvap = 30.2 kj/mol = 30200 J/mol

Also, we know that R (gas constant) = 8.314 J/mol-K

This is a straightforward application of the Clausius-Clapeyron equation to determine the vapor pressure of a compound at various temperatures. We can rewrite the equation to get: P2 = P1 . eˣ

where x = δHvap/R [1/T1 - 1/T2]

Hence, we get, x = 30200/8.314 [1/278.55 - 1/303]

x = 3632.42 [0.0035 - 0.0033]

x = 3632.42 [0.0002]

x = 0.726

Putting this value in modified Clausius-Clapeyron equation :

P2 = P1 . e⁰·⁷²⁶

P2 = 100  . e⁰·⁷²⁶

P2 = 100 x 2.054

P2 = 205.4 mmHg

A piece of aluminum foil measures 8.65 cm by 8.31 cm and has a mass 0.313 g. the density of aluminum is 2.70 g/cm3. The thickness of the aluminum foil is 0.0016 cm.

Given,

The length (l) and breadth (b) of aluminum foil is 8.65cm and 8.31 cm. And let the thickness of the foil be 'x'.

The mass (m) of the foil is 0.313 g.

The density (D) of the aluminum is 2.70 g/cm³.

Density is defined as the ratio between mass and volume.

So, D = m/V

But V = l × b × x

you apply a constant horizontal force (directed to the right) on the left cylinder. let a be the acceleration you give to the system. for what range of a will all three cylinders remain in contact with each other?

Answers

The range of acceleration (a) for which all three cylinders will remain in contact with each other is determined by the maximum and minimum static friction forces between the cylinders.

The maximum static friction force between two cylinders is given by the formula:

f_max = μ_s * N

where μ_s is the coefficient of static grating between the two surfaces and N is the typical power following up on the chambers (equivalent to the gravitational power following up on every chamber). Assuming that the even power applied on the left chamber is more prominent than the most extreme static grating power between any two chambers, they will begin to slide on one another, and the framework won't stay in touch. Consequently, the speed increase ought to be to such an extent that:

f_max >= m * a

where m is the all out mass of the framework. Settling for a, we get:

a <= μ_s * g

where g is the speed increase because of gravity. Subsequently, the scope of speed increase (a) for which every one of the three chambers will keep in touch with one another is from 0 to μ_s * g.

The induced current is greatest when a) the magnet moves fast, so that it is inside the coil for a short time b) the south pole of the magnet enters the coil first c) the north pole of the magnet enters the coil first d) the magnet moves slowly so that it is inside the coil for a long time

Answers

A bar magnet is passed through a coil of wire. The induced current is greatest when the north pole of the magnet enters the coil first.

This is because when a magnet is passed through a coil of wire, the induced current is greatest when the north pole of the magnet enters the coil first. This is due to the fact that the field lines of the magnet run from the north pole to the south pole, and when the north pole enters the coil, it creates a stronger magnetic field in the coil, which induces a greater current.Induced current is an electric current that is generated in a conductor due to a changing magnetic field. This type of current can be generated through Faraday's law of induction, which states that a changing magnetic field will induce a voltage in a conductor.

what magnitude of acceleration does it need to have to come to a complete stop in a distance of 200 ft ?

Answers

The magnitude of acceleration required to come to a complete stop in a distance of 200 ft depends on the initial velocity of the object.

What is acceleration?

Acceleration is the rate of change of an object's velocity. It is usually measured in meters per second squared (m/s2) and is often denoted by the letter "a". Acceleration can be caused by a variety of factors, including a change in speed, direction, or both. It is often associated with gravity, as objects naturally accelerate towards the ground due to the force of gravity. However, acceleration can be caused by any external force, such as a rocket engine, a car engine, or a person pushing an object. Acceleration is used in many aspects of physics, such as calculating the motion of an object, the force of a collision, and the acceleration of an object due to gravity. It is also used to calculate the amount of energy required to launch a rocket into space. Acceleration can be used to describe the speed at which an object is moving, as well as the rate at which it is changing direction.

during takeoff a jet aircraft goes from 0 m/s to 60 m/s in 5 seconds. what is the jet’s speed after 22 seconds if the acceleration was kept constant?

Answers

The jet’s speed after 22 seconds if the acceleration was kept constant is 260m/s during takeoff a jet aircraft goes from 0 m/s to 60 m/s in 5 seconds.

Given the initial velocity of jet aircraft (u) = 0m/s

The final velocity of jet aircraft (v) = 60m/s

Time taken to reach final velocity (t) = 5s

Let the acceleration be = a

From Newtons laws of motion, we know that v = u + at such that v = at

Then, a = v/t = 60/5 = 12m/s^2

Here, the acceleration was kept constant. So, v^2 = 2as where s is the distance covered.

Then, s = 60 x 60/ 2 x 12 = 150m

The time changed to t2 = 22s

The speed after after this time = v2

Then, v2 = at2 = 12 x 22 = 264m/s

Hence, the jet’s speed after 22 seconds is 264m/s.

This is a practice problem from AP Physics C; Mechanics class and we're currently working on momentum / center of mass-Students are going to perform an experiment to determine the launch speed v of a metal sphere from a launcher, using the setup shown above. They are expected to find the launch speed v by plotting their data in a graph. The students have access to equipment commonly found in a high school physics laboratory, but the experiment must use the setup as shown above, which includes a metal sphere with mass m1 and a block of mass M2 hanging from the ceiling by light strings of negligible mass. There is a hole inside the block where the metal sphere can be captured, and additional small masses can be attached to the peg on the block, as shown. Assume that the spheres velocity is horizontal when it collides with the block and the sphere collides with the block with its launch speed v.(a) Briefly identify each quantity to be measured, the symbol used to represent that quantity, and the equipment that would be used to measure the quantity.-(b) Briefly describe the procedure to be used to determine the launch speed v of the sphere.
