Answer:
a)1.51*10^-22joules b) 1.89*10^-7m
Explanation:
Work done to stop the proton = the kinetic energy of the proton = 1/2 mv^2 = 1/2* 1.67*10^-27* 425*425 = 1.51* 10 ^ -22 joules
b) net force acting to stop the proton = 8.01*10^-16
Work done needed to stop the proton = net force acting opposite the motion * distance
Distance covered = need work done/ net force
Distance = 1.51*10^-22/8.01*10^-16= 1.89*10^-7m
Answer:
True
Explanation:
Lose of water content in our body through sweating and lose of essential salts such as potassium and sodium causes heat cramps...
Thank you
No, because an atom consists of two main parts and three subatomic particles - protons, neutrons, electrons. Each one is smaller than an atom, therefore they are subatomic particles. An atom only requires protons and electrons to be an atom - Hydrogen has 1 proton and 1 electron. Neutrons DO NOT affect the overall charge of the atom, and only increase the atomic mass.
The change in momentum of an object equals the impulse applied to it
