Imagine a car crash. A car coming at a high speed has a head on collision with a car at rest. When the car makes impact, it will move the other car with it at a slower speed then it was travelling at. In this case, the velocity decreased since the car slowed down, but the mass increased since there are now two cars moving. Momentum was conserved because the change in mass accounts for the loss of velocity.
Answer:
Wavelength=75 cm.
The wavelength well remain unchanged which is 75 cm.
Explanation:
The formula which will help us to answer the question is:
V=f*λ
Where:
V is the velocity
f is the frequency of wave
λ is the wave length
Now:
λ=V/f Eq (1)
The equation show's that wavelength is independent of the amplitude but it depends on the frequency and the velocity with which wave is moving.
The wavelength well remain unchanged which is 75 cm.
Answer: 1) 17.65 * 10^-12 C/V; 2) 0.68 V
Explanation: In order to calculate the capacitance of one cylinder capacitor we have to use the following expression:
where and b are the inner and outer radius of teh cylinder, respectively. L is length of the cylinder.
Finally we also kwn that C=Q/ΔV
then we have
ΔV =Q/C
ΔV = 12 * 10^-12/17.65*10^-12= 0.68V
Answer:
≈933.3kg/m^3
Explanation:
Density=Mass/Volume
