Because if I do 0*time you get the answer as 0
Answer:
According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.


f = force
m = mass
a = acceleration
^^^^^^^^^^^^^^^^^^^^^^^^^^^ is correct
Frequency= velocity of light/wave length
Fr= 3×10^8/510×10^-9
Frequwency=5.88×10^14 Hz
