The distance between two successive crests or two successive troughs is the wavelength for a transverse wave. The height of the crest from the undisturbed water position or the depth of the trough from the undisturbed water position is the amplitude of the wave.
4 blocks north because he is it not asking for north east
Answer: The gravitational
Explanation: The student is pushing the box so u have to have gravitational force so it could move
Answer:
The velocity of other mass is 3.60 m/s.
Explanation:
Given that,
Mass of first block = 8 kg
mass of second block = 4.3 kg
Speed = 6.7 m/s
We need to calculate the speed of first mass
Using conservation of momentum

where, m₁ =mass of first block
m₂ =mass of second block
m₁ =mass of first block
v₂ =speed of second block
Put the value into the formula



Negative sign represent the opposite direction of initial value.
Hence, The velocity of other mass is 3.60 m/s.
