Answer:

v = 49.05 m/s^2

Explanation:

Let's use the uniform acceleration equation to find our final velocity.

v = u + at

v = final velocity

u = initial velocity

a = gravitational acceleration

t = time taken

Assuming the rock is at rest initially, u becomes zero.

v = 0 + 9.81(5)

v = 49.05 m/s^2

When a sound source is moving toward the observer, the observer will hear a higher pitch. This is due to
Goryan [66]
Number one a and b are automatically out if you decrease the pitch or frequency you wont hear it louder it does not add up ok?
number 2 the answer would be C the higher the frequency the higher the pitch the lower the frequency the lower the pitch this just comes back to common sense. for example you cant decrease the frequency and than expect a louder pitch its like saying I am going to smash the key on this piano with all my strength and it will make a small very low pitch sound you get what I mean so your answer would indeed be C.

Q.01 When charging a secondary cell, energy is stored within a dielectric material using an electric field. True or False
Nitella [24]

True, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

<h3>Relationship between dielectric material and electric field</h3>

The electric field in a capacitor separates the negative and positive charges in the dielectric material, this causes an attractive force between each plate and the dielectric.

The dielectric material can store electric energy due to its polarization in the presence of external electric field, which causes the positive charge to store on one electrode and negative charge on the other.

Thus, when charging a secondary cell, energy can be stored within a dielectric material using an electric field.

For photons of 50 keV, 500 keV, and 5 MeV, what will be the most likely init interaction with tissue?
love history [14]

Answer:

50 KeV

Explanation:

50 KeV will be the most likely initial interaction with tissue.

Because Higher the energy lesser will the interaction with tissues, Because it will penetrate through tissue more easily in a very lesser time Whereas the photon with least energy will take more time to penetrate through the tissue, hence, higher interaction with tissue.
