Light year is the unit of distance. It is the distance that an object travels in one year with the speed of light.
In short, Your Answer would be "Distance"
Hope this helps!
Acceleration =
(change of speed) / (time for the change).
Change of speed = (speed at the end) - (speed at the beginning)
= ( zero ) - (40 m/s)
= -40 m/s .
Acceleration = (-40 m/s) / (5 seconds)
= -8 m/s² .
It is a kinetic type of jump
Question: A ship anchored at sea is rocked by waves that have crests 100 m apart the waves travel at 70m/S, at what frequency do the waves reach the ship?
Answer:
0.7 Hz
Explanation:
Applying,
v = λf............... Equation 1
Where v = velocity of the wave, f = frequency fo the wave, λ = wavelength of the wave
make f the subject of the equation
f = v/λ................. Equation 2
From the question,
Given: v = 70 m/s, λ = 100 m ( distance between successive crest)
Substitute these values into equation 2
f = 70/100
f = 0.7 Hz
Hence the frequency at which the wave reach the ship is 0.7 Hz
