F - False.
The law of conservation of momentum states that the total momentum is conserved.
Answer:
a)1500N
b)153.06kg
Explanation:
F = ma
g(moon) = is the acceleration due to gravity on the moon
g(earth) is the acceleration due to gravity on the earth
g(moon) = 1/6g(earth)
g(earth) =6g(moon)
F(gearth) = mg(earth)
= m 6g(moon)
= 6 × 250
= 1500N
b) F(gearth) = mg(earth)
m = F /g
= 1500/9.8
= 153.06kg
A. W
Explanation:
The wave that would be produced by the interaction of the two waves shown in the diagram is wave W.
There is no wave in the diagram W.
This type of interference is known as destructive interference.
- Destructive interference occurs when two waves out of phase comes together.
- In this way, they cancel out each other and are terminated.
- If the two waves are in phase, they will reinforce one another.
- When waves reinforce one another, a constructive interference has occurred.

Answer:
v = 3200 m/s
Explanation:
As we know that the frequency of the sound wave is given as
![f = 400 Hz](https://tex.z-dn.net/?f=f%20%3D%20400%20Hz)
wavelength of the sound wave is given as
![\lambda = 8 m](https://tex.z-dn.net/?f=%5Clambda%20%3D%208%20m)
so now we have
![speed = wavelength \times frequency](https://tex.z-dn.net/?f=speed%20%3D%20wavelength%20%5Ctimes%20frequency)
so we will have
![v = (8m) \times (400 Hz)](https://tex.z-dn.net/?f=v%20%3D%20%288m%29%20%5Ctimes%20%28400%20Hz%29)
![v = 3200 m/s](https://tex.z-dn.net/?f=v%20%3D%203200%20m%2Fs)
