When a neutron or a proton in the nucleus changes a gamma ray is produced (gamma rays are electromagnetic waves)
When an electron drops from a higher energy level to a lower energy level an electromagnetic wave is give off.
The force required is
(15 kg) x (the acceleration, in m/s²) newtons.
<span>The velocity will be 41.25 m/s2 after 9 seconds. To find velocity after a specific time period, multiply the acceleration (2.75) times the number of seconds (9) to receive 24.75 m/s, then add that to the initial velocity of 16.5 m/s. 24.75 + 16.5 = 41.25 m/s2.</span>
Answer:
Explanation:
As we know that the electrostatic force is a based upon inverse square law
so we have
now since it depends inverse on the square of the distance so we can say
now we know that
also we know that
now from above equation we have
Below is the answer. I hope it help.
T ( t ) = C e k t + T m where Tm is the temperature of the surroundings
T ( t ) = C e k t + T m
T ( 0 ) = 20
T ( 1 ) = T ( 0 ) + 2 = 22
C + T m = 20 C+Tm=20
C e k + T m = 22
