Considering the Doppler efect, the frequency heard by the student would change if:

The Doppler effect is defined as the change in the apparent frequency of a wave produced by the relative motion of the source with respect to its observer. In other words, this effect is the change in the perceived frequency of any wave motion when the sender and receiver, or observer, move relative to each other.

In summary,  there is always a change in the frequency of sound as the source of the sound moves towards or away from the observer. So, the Doppler Effect is an alteration of the observed frequency of a sound due to the movement of the source or the observer, that is, they are changes in the frequency and wavelength of a wave due to the relative movement between the wave source and the observer.

In this case, considering the Doppler effect, the frequency heard by the student would change if:

Answer:

D

Explanation:

The friction force is the weight force times the coefficient of friction. So diving by the coefficient gives you the weight force which is equivalent to the normal force.

The equation that we can used to determine the frictional force using the coefficient of kinetic friction and the normal force is given by the expression : F = u N.

Where N is the normal force by the weight of the body.

Frictional force is a type of force acting on a body to prevents its motion. Hence, the frictional force is always negative. Frictional force acting on an object is making a resistance to the motion of the object.

There are both kinetic frictional force and static frictional force. The coefficient of frictional force is the ratio of the frictional force to the normal force on the object. The normal force on the object is equal to m g that is the force by its own weight.

If u is the coefficient of kinetic friction and N be the normal force acting on the object, then the force of kinetic frictional force F is given by,

F = u N.

Where N = mg.

Except for Pluto, all of the planets in the solar system have slightly elliptical orbits.    

Pluto, a dwarf planet, the orbit is highly elliptical, with an eccentricity of 0.25, and it travels between 4.4 and 7.4 109 kilometers (2.7-4.6 109 miles) from the Sun on average. As a result, Pluto's orbit occasionally brings it closer to the Sun than Neptune, which implies that sometimes Pluto is much closer to the Sun than other times.

Pluto orbits the Sun at an angle of 17 degrees. This indicates that Pluto occasionally orbits above the other planets and occasionally orbits below them.

Explanation:

An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level but liquid pressure is exerted on the surface of an object in a liquid.

And they also differ in formulas. We can calculate atmospheric pressure in two ways. First we can get the atmospheric pressure by an instrument called barometer. And the second one is by usin this formula, atmospheric pressure = density of mercury x acceleration due to gravity x height of column of mercury. But this equation will only work if the atmospheric pressure is being measured by mercury.

But the formula for liquid pressure is defferent and the instrument used to measure the liquid pressure is also defferent.

The instrument used to measure the liquid pressure is pressure gauge. And the formula for the liquid pressure is density x height x gravity. Please give me a like and thank me.

When a substance changes from a liquid to a solid, they move more slowly and become fixed in position. Option A is correct.

When a substance changes from a liquid to a solid, its particles lose energy and move more slowly. As the temperature decreases, the particles lose kinetic energy and start to arrange themselves into a fixed, ordered pattern. This causes the substance to solidify and the particles become fixed in position.

The transition from a liquid to a solid state is called freezing or solidification. During this process, the particles lose energy and their motion becomes more restricted, causing them to move more slowly and eventually become fixed in position. Option A is correct.

h ⇒ height ⇒ 4.5 cm

Let us find it now.

V = [tex]\frac{1}{3}[/tex] × π r² h

V = [tex]\frac{1}{3}[/tex] × π × 3 × 3 × 4.5

V = [tex]\frac{1}{3}[/tex] × π × 9 × 4.5

V = [tex]\frac{1}{3}[/tex] × π × 9 × 4.5

V = [tex]\frac{1}{3}[/tex] × π × 40.5
