Answer:
Acceleration of proton will be 
Explanation:
We have given a proton is placed in an electric field of intensity of 700 N/C
So electric field E = 700 N/C
Mass of proton 
Charge on proton 
So electric force on the proton 
This force will be equal to force due to acceleration of the proton
According to newton's law force is given by F = ma
So 

So acceleration of proton will be 
We can make pretty good guesses for their masses, but kinetic energy also depends on their speeds, which we don't know, and may change.
As an example ... If the truck, the van, the car, and the bike are all parked at the mall, then a scampering mouse has more kinetic energy than all of them combined.
As the question stands, no answer is possible.
Answer:
yes it is
Explanation:
when the speed increases the car will vibration than egg will breaks
Answer:
I think D
Explanation:
if energy is added,it wont stay the same,I beleive D is the only one that makes since,sorry if wrong
