Answer:
a. s = 0.96 m
b. s = 2.15 m
Explanation:
a.
The relationship between the linear displacement and the angular displacement is given as follows:

where,
s = linear distance covered = ?
r = radius of wheel = (6 in)(0.0254 m/1 in) = 0.1524 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,

<u>s = 0.96 m</u>
<u></u>
b.
Assuming, we have to find linear displacement here, as well:

where,
s = linear distance covered = ?
r = radius of wheel = (13.5 in)(0.0254 m/1 in) = 0.3429 m
θ = angular displacement = (1 rev)(2π rad/1 rev) = 2π rad
Therefore,

<u>s = 2.15 m</u>
I believe the answer would be A that you move the lever away from you to load the rifle (I know since I had such a rifle). This action places a shell into the firing chamber so that it is ready to fire so makes it convenient to re-load unlike where a shell must be placed in the chamber by hand each time such as is the case with many 0.22 rifles.
Answer:
D
Explanation:
At the other end of the spectrum toward red, the wavelengths are longer and have lower energy.
Answer:
The galaxy is moving away from us
Explanation:
Galaxy refers to a system of millions or billions of stars accompanied by gas and dust such that they are held together as a result of gravitational attraction.
When we observe a distant galaxy, we find that a spectral line of hydrogen that is shifted from its normal location in the visible part of the spectrum into the infrared part of the spectrum.
It means that the galaxy is moving away from us.
