Atmosphere is one but that’s all I know
Answer:
The change in momentum of the car is 16380.8 kg.m/s
Explanation:
Given;
mass of the car, m = 1600 kg
time of motion, t = 4.20s
force of friction on the car, F = 3900 N
final velocity of the car after the brakes were applied, v = 0
The initial velocity of the car during the motion is calculated as;
The change in momentum of the car is calculated as;
ΔP = mu
ΔP = 1600 x 10.238
ΔP = 16380.8 kg.m/s

Answer:
a) their amplitudes are the same their phase difference is constant their frequencies are the same
Explanation:
Coherent waves are the waves that have constant phase difference, equal frequency, amplitude and waveform.
Frequency denotes the number of cycles a wave completes in one second.
Amplitude is the maximum height that the wave reaches.
Waveform is the two dimensional representation of a wave in graphical form.
Answer: Electron flow / Electric current
