Answer:
Momentum = 150 000 kgm/s
Explanation:
Momentum = mass × velocity
Given that,
Therefore, momentum = (10 000 × 15)kgm/s
Momentum can be found by multiplying the mass by the velocity.
The mass of the space ship is 10,000 kilograms and its velocity is 15 meters per second.
Substitute the values into the formula.
Multiply
The momentum of the space ship is 150,000 kilograms meters per second
The amplitude ( ) of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom of a trough . Be careful with this quantity - the centre line is not always given in a diagram.
I think it is transpiration
21.6m
Distance=speed×time
=1.2m/s×18min
=21.6m
