The horizontal distance covered by this water slide is equal to 13.23 meters.The angle formed between the water slide and the horizontal plane is equal to 48.59°.The magnitude of Eric's weight is equal to 392 Newton.The magnitude of the normal force Eric receives from the water slide is equal to 258.72 Newton.The magnitude of the normal force Eric gives from the water slide is equal to 258.72 Newton.The magnitude of his gravitational force's component parallel to the water slide is equal to 294 Newton.Eric's acceleration is equal to 6.70 m/s².Eric's speed is equal to 16.37 m/s.At least, the superman has to apply a force of 133.28 Newton.

How to determine the horizontal distance?

Based on the information provided, we can infer and logically deduce the following salient points and parameters:

Height of water slide (Adjacent) = 15.0 meters.Length of water slide (Hypotenuse) = 20.0 meters.

This ultimately implies that, the horizontal distance covered by this water slide represents the opposite side of a right-angled triangle and as such we would apply Pythagorean theorem.

Mathematically, Pythagorean theorem is given by this formula:

c² = a² + b²

Where:

h is the hypotenuse of a right-angled triangle.a is the adjacent side of a right-angled triangle.b is the opposite side of a right-angled triangle.

Substituting the given parameters into the formula, we have;

20.0² = 15.0² + b²

b² = 20.0² - 15.0²

b² = 400.0 - 225.0

b² = 175.0

b = √175.0

b = 13.23 meters.

Thus, we would apply sine trigonometry to determine the magnitude of the first complimentary angle (θ₁) formed by this right-angled triangle:

Sinθ₁ = Opp/Hyp

Sinθ₁ = 13.23/20.0

Sinθ₁ = 0.6615

θ₁ = sin⁻¹(0.6615)

θ₁ = 41.41°.

How to calculate the angle?

We know that θ is the angle formed between the water slide and the horizontal plane. Thus, we would determine the magnitude of this second complimentary angle (θ₂):

θ = θ₁ + θ₂

90° = 41.41° + θ₂

θ₂ = 90° - 41.41°

θ₂ = 48.59°.

From the above, we have:

Sinθ₂ = Sin(48.59) = 0.75.

Cosθ₂ = Cos(48.59) = 0.66.

Tanθ₂ = Tan(48.59) = 1.134.

How to determine the magnitude of Eric's weight?

Mathematically, the weight of a physical body (object) can be calculated by using this formula:

Weight = mg

Weight = mass × acceleration due to gravity

Weight = 40.0 × 9.8

Weight = 392 Newton.

How to determine the magnitude of the normal force?

Mathematically, the magnitude of the normal force Eric receives from the water slide is given by:

Normal force = mgcosθ

Normal force = 40.0 × 9.8 × cos(48.59)

Normal force = 392 × 0.66

Normal force = 258.72 Newton.

How to determine the magnitude of the normal force?

Mathematically, the magnitude of the normal force Eric gives the water slide is given by:

Normal force, Fₙ = mgcosθ

Normal force, Fₙ = 40.0 × 9.8 × cos(48.59)

Normal force, Fₙ = 392 × 0.66

Normal force, Fₙ = 258.72 Newton.

How to determine the gravitational force component?

Mathematically, the magnitude of his gravitational force's component parallel to the water slide is given by:

F = Wsinθ = mgsinθ

F = 40.0 × 9.8 × sin(48.59)

F = 392 × 0.75

F = 294 Newton.

How to calculate the friction force?

Mathematically, the magnitude of the friction force between Eric and the water slide is given by:

Fs = μ_s(Fₙ)

Fs = 0.10 x 258.72 N

Fs = 25.872 Newton.

How to calculate Eric's acceleration?

First of all, we would determine the net force acting on Eric?

F(net) = F - Fs

F(net) = 294 - 25.872

F(net) = 268.13 Newton.

From Newton's second law of motion, acceleration is given by this formula:

Acceleration = Net force/Mass

Acceleration = 268.13/40.0

Acceleration = 6.70 m/s².

How to calculate Eric's speed?

In this scenario, we would calculate Eric's speed by using the third equation of motion:

V² = U² + 2aS

V² = 0² + 2(6.70)(20.0)

V² = 268

V = √268

V = 16.37 m/s.

At least, the superman has to apply the following force to prevent Emily from sliding:

Force = Weight - Normal force

Force = 392 - 258.72

Force = 133.28 Newton.

What mechanisms function to localize sound in the horizontal and vertical planes?

Answers

What mechanisms function to localize sound in the horizontal and vertical planes?

Horizontal sound localization results from two mechanisms: interaural time delay and interaural intensity difference.

What is localizing sound?

The capacity to pinpoint the position or source of a detected sound in terms of distance and direction is known as sound localization.

Numerous studies have been conducted on the mammalian auditory system's sound localization mechanisms. The auditory system uses a variety of indicators, such as spectral information, timing difference, level difference (or intensity difference) between the ears, and others, to locate the source of sound. Other animals, including birds and reptiles, employ these cues as well, however there may be variances in how they are used. In addition, there are localization cues that are not present in the human auditory system, such as the results of ear movements. It is obvious that animals that can localize sound have an evolutionary advantage.

What is time dilation and how does it effect aging in life around the universe.

Answers

Hi, your answer is below.

Time dilation is usually defined as the slowing of the passage of time experienced by objects in motion relative to an observer; measurable only a relativistic speeds.  Because time moves at various rates for the two of them depending on their relative velocities and/or proximity to things of considerable mass, if two persons (or objects) are moving relative to one another, they will age at separate rates. They will age differently from one another over time since their two timepieces will really tick at separate speeds. If they cross paths again later, they will both have aged differently, which may be determined by using their own timepieces, presuming they each had one. Einstein's Special and General Relativity equations, which have undergone extensive testing over the past 115 years and have never been shown to falter, regulate this "time dilation." The general relativity theory of Einstein, which states that a huge body's gravity warps space-time around it, causes time to move more quickly or more slowly depending on how far away the mass is from the observer, is what causes this so-called "time-dilation" phenomenon.

Thank you,

Metallic iron crystallizes in a body-centered cubic lattice, with one fe atom per lattice point. if the metallic radius of fe is 124 pm, what is the volume of the unit cell in pm3 and in cm3?

Answers

The volume of a unit cell is 4.3 × 10⁻¹⁰ pm³.

We need to start with the features of a face-centered cubic system in order to be able to determine the edge length of the unit cell.

As we know, a face-centered cubic system is characterized by a unit cell that has a total of 14 lattice points.

one lattice point for every one of the eight corners of the unit cell.one lattice point for every one of the six faces of the unit cell.

Now, these lattice points will contain

1/8th of an atom in every corner lattice point.1/2 of an atom in every face lattice point.

Assume that r is the edge length of the unit cell and that r is the radius of an iron atom. You'll see that we can represent x in terms of the cell's diagonal, d, using Pythagoras' Theorem.

        [tex]d^2 = x^2+ x^2[/tex]

        [tex]d^2=2x^2[/tex]

The cell's diagonal will be equal to one radius from the atom in the top corner, two from the atom in the face, and one from the atom in the lower corner.

[tex]d= r+2r+r = 4r[/tex]

This means that we have,

[tex](4r)^2=2x^2[/tex]

[tex]16.r^2 = 2x^2 \\x=\sqrt{8r^2}[/tex]

This is equivalent to

[tex]x=2\sqrt{2} r = 2\sqrt{2} .124= 350.7 pm[/tex]

So, the edge length of the unit cell is equal to 350.7 pm.

The volume of a unit cell. As we know, the volume of a cube is given by the formula

V = [tex]l[/tex] × [tex]l[/tex] × [tex]l[/tex]

[tex]l[/tex] = the edge length of the cube

Volume = (350.7)³ pm³

            = 4.3 × 10⁻¹⁰ pm³

            = 4.3e-30 cm³

Therefore, the volume of the unit cell is 4.3 × 10⁻¹⁰ pm³.

An organization is located in an area that experiences frequent and lengthy power blackouts. what will the effect of an electric generator be in this circumstance?

Answers

Electric utility power blackouts will result in short electric power outages for the organization.

Power blackouts :

When the electrical power network, often known as the electrical grid, is down, there are power outages. Power outages can have a variety of causes, but they always tend to affect entire regions or cities rather than simply a single residence. For example, the Northeast blackout of 2003 left 50 million people without power from New York to Canada’s capital Ottawa.  

A place experiences a blackout when all power is lost. Power outages of this kind generally affect a sizable population over perhaps extraordinarily broad areas. Blackouts are particularly difficult to quickly fix because they typically result from significant damage to electrical generation facilities (such as structural damage from violent wind storms or lightning strikes). As a result, these types of outages can, in the worst-case scenarios, last for several weeks.

The unit of the quotient of inductance and resistance will be Henry and ohm

Inductance is the tendency of an electrical conductor to oppose a change in the electric current flowing through it. The flow of electric current creates a magnetic field around the conductor. The field strength depends on the magnitude of the current, and follows any changes in current.

Resistance is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). Ohms are named after Georg Simon Ohm (1784-1854), a German physicist who studied the relationship between voltage, current and resistance.

When a proton slows from 0. 8c up to 0. 6c, it’s kinetic energy decreases by what factor?

Answers

When a proton slows from 0. 8c up to 0. 6c, it’s kinetic energy decreases by what factor of 1/4.

Kinetic energy of a proton having a charge Q and Voltage V is given by:

Kinetic energy = Q×V

Where, Q is the charge

            V is the Voltage

Kinetic energy is directly proportional to the charge on a proton.

Let the kinetic energy of proton having charge 0.8C be KE₁ and kinetic energy of proton having charge 0.6C be KE₂

Hence KE₁ = 0.8 × V

KE₂ = 0.6 × V

Now, KE₁ / KE₂ = 0.8 V / 0.6 V

⇒          KE₁ / KE₂ = 4 / 3

⇒         KE₂ / KE₁ = 3/4

⇒         KE₂ = 3/4 times KE₁

Hence, the final kinetic energy becomes 3/4 times the initial kinetic energy.

The kinetic energy decreases by a factor of:

Change = KE₁ - KE₂

Change = KE₁ - 3/4KE₁

Change = 1/4 KE₁

Hence, the kinetic energy decreases by a factor of 1/4

The wavelengths of the light are 4.3 * 10^-12 m and 0.2 m respectively.

What is wavelength?

The term wavelength has to do with the horizontal distance that is covered by a wave. We know that a long wavelength implies that the wave is able to travel a long distance from one point to another.

Given that;

c = λf

c = speed of light

λ = wavelength of ight

f = frequency of light

Thus;

λ = 3 * 10^8/ 7.00 x 10^19

λ = 4.3 * 10^-12 m

λ = 3 * 10^8/1.50 x 10^9

λ = 2 * 10^-1 or 0.2 m

Answers

A low partial pressure of oxygen promotes hemoglobin binding to carbon dioxide. This is an example of the  Haldane effect

The less saturated hemoglobin is and the lower the partial pressure of oxygen in the blood is, the more readily hemoglobin binds to carbon dioxide. This is an example of the Haldane effect.

The Haldane effect is a property of hemoglobin first described by John Scott Haldane, within which oxygenation of blood in the lungs displaces carbon dioxide from hemoglobin, increasing the removal of carbon dioxide. Consequently, oxygenated blood has a reduced affinity for carbon dioxide.

In general, which lens had the largest overall magnification (enlarged more than reduced)?

Answers

Convex lens  had the largest overall magnification .

In optics, It is a quantification of comparing the size of the image with respect to the size of the object. It gives us information about the image in terms of how large or small is the image formed. Magnification is defined as the ratio of the height of image to the height of object.

The convex lens has the largest overall magnification. To get maximum magnification by convex lens object must be placed between center of curvature and pole of the lens .

Magnifying glasses make objects appear larger because their convex lenses (convex means curved outward) refract or bend light rays, so that they converge or come together.

Two rockets approach each other. each is traveling at 0. 84 cc in the earth's reference frame. part a what is the speed of one rocket relative to the other?

Answers

The speed of one rocket relative to the other is 8.5 cc.

Let s be the frame at rest relative to the earth. Let the spaceship moving to the left with respect to the earth at speed [tex]v[/tex] be the particle in the terminology. Then the velocity of the spaceship relative to each other is simply the velocity of the second spaceship.

That for speeds small compared with the speed of light the relativistic velocity addition law gives the usual Newtonian result, whereas for speed near c the result is not what has been expected classically.

[tex]v' = 0.96cc\\\\v= 0.84cc\\\\\\v' = \frac{v+V}{1+ \frac{vV}{c^2} } \\\\v' = \frac{v+V}{ \frac{c^2+ vV}{c^2} }\\\\v' = \frac{(v+V) c^2} {c^2+ vV}\\\\\\v'c^2 + c^2v = V (c^2 - v'v)\\\\V = \frac{v'c^2+c^2v}{c^2 - v'v} \\ \\ = \frac{0.96 * 9* 10 ^1^6 + 0.84*9*10^1^6}{9*10^1^6 - 0.96 * 0.84} \\\\ =\frac{16.2}{1.9}\\ \\= 8.5 cc[/tex]

A basketball player has a 0. 603 probability of making a free throw. if the player shoots 10 free throws, what is the probability that she makes exactly 6 of them?

Answers

The probability that she makes 6 of them is 0.242

Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

A basketball player has a probability = 0. 603

The player shoots 10 free throws.

Let x be a random variable that represents the number of free throws made by a basketball player.

x ≈ Binomial (n,p)

p = 0.603

n= 10

P(x=k) = [tex]_nC_k p^k (1-p)^{n-k}[/tex]

P(6)    [tex]= _1_0C_6 (0.603)^6 (1-0.603)^{10-6}[/tex]

           [tex]=210 (0.048) (0.397)^4[/tex]
