Answer:
D) accelerate but will not spin.
Explanation:
On the off chance that there is no air resistance the object will accelerate yet won't turn, this is on the grounds that without air resistance same force is applied on each bit of the object. Force on each segment is coordinated descending i.e parallel force. So there is no force to deliver spin movement in it.
It will accelerate because of gravity
Answer: Velocity = v = 35 m/s
Explanation:
Kinetic energy of an object is defined as the energy possess by an object due to its motion. Kinetic energy K.E of an object is equal to the half of the mass of that object multiplied by square of the object's velocity.
Mathematically,
v = 35 m/s
Answer:
Yes, correct
Explanation:
velocity, v = 470 m/s
radius, r = 0.15 m
The radial acceleration is the centripetal acceleration which always acts towards the centre of the circular centrifuge.
The formula for the centripetal acceleration is given by


a = 1472666.667
a = 150272.1 g
According to the question, we can get the acceleration as mentioned. So the claim is correct.
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.
Both c and a could be right but I am steering more towards a.
