Answer:
2.1406 ×
m/sec
Explanation:
we know that energy is always conserved
so from the law of energy conservation

here V is the potential difference
we know that mass of proton = 1.67×
kg
we have given speed =50000m/sec
so potential difference 
now mass of electron =9.11×
so for electron

so the velocity of electron will be 2.1406×
m/sec
Answer:
Radiation
Explanation:
The sun radiates energy to the earth to make it warmer near the equator.
Answer:
the change in momentum = Force x change in time
Y, bc the height of the bounce back is higher than x
