Answer:
amu is atomic mass unit
All of elements hydrogen is the lightest.
Hydrogen is taken as a basic unit so it happened 1amu
So 1 amu must be hydrogen mass
If I am wrong,Pls tell me the true answer....
Answer:
0.85 c
Explanation:
When the two travel at right angles to each other , their relative velocity is given by the hypotenuse formed by the x and y direction velocities.
Relative velocity of the two protons is given as
If v = 3/5 c , then the relative speed = 
(3/5c) =0.85 c
There are two main types of electrical charges.
Answer: pick A moves 10.2 metre
Explanation: since they were given a quick push simultaneously the product of their distance moved and velocity would be equal.
Let the distance moved by puck B x then that of puck A would be 18-x.
So therefore we have that,
1.3*(18-x) = 1.7*x
23.4 - 1.3x = 1.7x
23.4=3x
Making x subject of formula we have
x = 23.4/3 = 7.8m
But the distance moved by puck A is 18-x. So therefore,
18-7.8=10.2meter
