Answer:
c. The force exerted by the train on the wall was the same in magnitude as the force exerted by the wall on the train.
Explanation:
Newton's Third Law states that if a body exerts a force on another body, this body exerts a force of equal magnitude but in the opposite direction on the body that produces it. So, one body cannot exert a force on another without experiencing a force in itself.
Answer:
if you mean the regions during slavery, North, but if in general, East. (think East Coast)
Answer:
The ratio of moment of inertia of larger sphere to that of smaller sphere = 4
Explanation:
The moment of inertia of solid sphere is given by I = 2/5MR² where M = mass of sphere and R = radius of sphere.
Radius of smaller sphere = D/2
Radius of larger sphere = 2D/2 = D.
Moment of inertia of smaller sphere I₁ = 2/5M × D²/4 = MD²/10
Moment of inertia of larger sphere I₂ = 2/5M × D² = 2MD²/5
The ratio of moment of inertia of larger sphere to that of smaller sphere = I₂/I₁ = 2MD²/5 ÷ MD²/10 = 10 × 2/5 = 4
Answer:
decreases
Explanation:
Remeber:
There is always inverse relation between frequency and wavelength.
So if one of them increases, other decreases and vice-versa.
f ∝ 1 / λ
Answer:
This is the information I can provide. I hope it helps
Explanation:
Frequency is measured in units of hertz (Hz) which is equal to one occurrence of a repeating event per second. The period is the duration of time of one cycle in a repeating event, so the period is the reciprocal of the frequency.
