Answer:
The crest to trough distance = 8 m
Explanation:
Given that,
The amplitude of a particular wave is 4.0 m.
We need to find the crest to trough distance.
We know that,
Amplitude = The distance from the base line to the crest or the the distance from the baseline to the trough.
It means,
Distance from crest to trough = 2(Amplitude)
= 2(4)
= 8 m
Hence, the crest to trough distance is equal to 8 m.
Which way is it being pulled?
Sound must travel through a medium/body. Space is a vacuum so there is no medium/body for sound to travel through, so there is no sound.
Answer:
m = 327.07 kg
Explanation:
Given that,
Kinetic energy of a motorcycle, E = 57800 J
Velocity of the motorcycle, v = 18.8 m/s
We need to find the mass of the motorcycle. The kinetic energy of an object is given by :

m is mass

So, the mass of the motorcycle is 327.07 kg.
1 kg of water = 1 L = 1 dm³
762 g of water = 762 cm³
