Uh.. what's the question..?
It's downward vector from the centre of apple in the direction to the centre of the Earth.
Answer:
The answer is ![1.956 \times 10^7\ m/s](https://tex.z-dn.net/?f=%201.956%20%5Ctimes%2010%5E7%5C%20m%2Fs)
Explanation:
The amount of energy is not enough to apply the relativistic formula of energy
, so the definition of energy in this case is
.
From the last equation,
![v= \sqrt{2E/m}](https://tex.z-dn.net/?f=v%3D%20%5Csqrt%7B2E%2Fm%7D)
where
![E = 2 MeV = 3.204 \times 10^{-13} J](https://tex.z-dn.net/?f=E%20%3D%202%20MeV%20%3D%203.204%20%5Ctimes%2010%5E%7B-13%7D%20J)
and the mass of the neutron is
.
Then
![v = 1.956 \times 10^7\ m/s](https://tex.z-dn.net/?f=v%20%3D%201.956%20%5Ctimes%2010%5E7%5C%20m%2Fs)
the equivalent of
the speed of light.
Answer:
can u send a picture to identify it
Explanation:
sorry I just need point:/
Option (D) is the correct one.
In order to increase the amount of work done, we need to increase the force applied to the object.
