The moon<span> is 1/4 the size of </span>Earth<span>, so the </span>moon's<span> gravity is much less than the </span>earth's gravity, 83.3% (or 5/6) less to be exact. Finally, "weight<span>" is a measure of the gravitational pull between two objects. So of course you would </span>weigh<span> much less on the </span>moon<span>.</span>
Answer:
The dentist uses X-ray radiography, which takes too short a time to cause those problems.

I took the test on Edg
Answer: ![83.65\times 10^{-27}\ kg.m/s](https://tex.z-dn.net/?f=83.65%5Ctimes%2010%5E%7B-27%7D%5C%20kg.m%2Fs)
Explanation:
Given
The velocities of the protons are 400 m/s and 450 m/s
Mass of the Proton is ![m=1.673\times 10^{-27}\ kg](https://tex.z-dn.net/?f=m%3D1.673%5Ctimes%2010%5E%7B-27%7D%5C%20kg)
Since they travel in the opposite direction, therefore, their momentum cancels out each other.
Momentum is the product of mass and velocity
![\therefore m(450-400)\\\Rightarrow 1.673\times 10^{-27}\times 50\\\Rightarrow 83.65\times 10^{-27}\ kg.m/s](https://tex.z-dn.net/?f=%5Ctherefore%20m%28450-400%29%5C%5C%5CRightarrow%201.673%5Ctimes%2010%5E%7B-27%7D%5Ctimes%2050%5C%5C%5CRightarrow%2083.65%5Ctimes%2010%5E%7B-27%7D%5C%20kg.m%2Fs)
The direction of momentum is in the direction of proton having 450 m/s velocity.
