The object was moving at constant velocity between the points on the graph that we marked 6 s to 8s.
<h3>
What is acceleration?</h3>
The term acceleration has to do with the change of velocity with time. In this case, we saw that the velocity of the car was not changed between 6 s to 8s.
Now , the object was moving at constant velocity between the points on the graph that we marked 6 s to 8s.

Answer:
11m
Explanation:
Wavelength of a wave is the distance between successive crests and trough of a wave. It is represented mathematically as the ratio of the speed of the wave to its frequency. It can be expressed as;
Wavelength ¶ = wave speed (v) /frequency (f)
Given the speed of light c = 2.9979 10^8 m/s.
frequency of the radio wave = 27.075 MHz = 27.075×10^6Hz
Wavelength = 2.9979 10^8/27.075×10^6
Wavelength = 0.11×10^2
Wavelength = 11m
Therefore, the wavelength of the electromagnetic wave being used is 11m
Answer:
240cm
Explanation:
Speed = 6cm/s
Time = 40 seconds
Speed= distance/time
6cm/s = distance/40seconds
Distance = 6×40
Distance = 240cm
Hence, in 40 seconds, the ball must have rolled the distance of 240cm
Answer:
dam/hydro power
Explanation:
estuary is the place where rivers meet the ocean, there are a lot of currents there (waves...) so it likely means thery use a dam or some sort of way of collecting electricity from the motion of the water there. many birds live in estuaries because of being able to find fish to feed from
