An airplane increases its speed at the average rate of 15 m/s2. How much time does it take to increase its speed from 100 m/s to 160 m/s

4 s

Explanation:

We are asked to calculate time taken (t).

By using the first equation of motion,

v = u + at

160 = 100 + 15t

160 - 100 = 15t

60 = 15t

60 ÷ 15 = t

4 s = t

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge
