The change in momentum of the ball is 0.6Kgm/s.
To find the answer, we need to know about the momentum.
<h3>What's the expression of change in momentum during collision?</h3>
- The change in momentum= final momentum - initial momentum of the objects
- And momentum= mass × velocity
<h3>What's the change in momentum here?</h3>
- Here the initial momentum= 0.10×30=3Kgm/s
- Final momentum= 0.10×24= 2.4Kgm/s
- Change in momentum= 3-2.4= 0.6Kgm/s
Thus, we can conclude that the change in momentum is 0.6Kgm/s.

Answer:
Explanation:
a = F/m = 7500/2000 = 3.75 m/s²
v² = u² + 2as
s = (v² - u²) / 2a
s = (0² - 45²) / (2(-3.75))
s = 270 m
The wavelength of the wave that you are tuning in decreases.
Explanation:
The relation that relates with the speed of wave, frequency of wave and wavelength is given as
Wavelength =
The speed of the wave in a medium remains constant and therefore the wavelength is inversely proportional to the frequency of wave.
That is if the frequency is increased, the wavelength decreases and the wavelength is increased as the frequency is decreased.
Hence, as you tune your radio to a higher frequency, from 88.5 FM to 103,3 FM, the wavelength of the wave that you are tuning in decreases.
