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
M=mv
=0.30x5.6
=2.016kgm/s
nanometers
to measure a virus you use nanometers
Answer:
It is because it cannot be used time again and again.
