What is velocity and acceleration?with examplesplzz and my question
2 answers:
Answer:velocity is defined as the displacement per unit time is called velocity. e. g
Acceleration is defined as the change of velocity of a body is called Acceleration. e. g if car moving with the constant velocity so Acceleration will be zero. If the velocity of car change so Acceleration also change.
The example of velocity is on picture...

Answer:
v= 1.71 m/s
Explanation:
Given that
Distance between two successive crests = 4.0 m
λ = 4 m
T= 7 sec
T is the time between 3 waves.
3 waves = 7 sec
1 wave = 7 /3 sec
So t= 7/3 s
We know that frequency f
f= 1/t= 3/7 Hz
Lets take speed of the wave is v
v= f λ
f=frequency
λ=wavelength
v= 3/7 x 4 = 12 /7
v= 1.71 m/s
