Answer:
<h2>6.67 m/s²</h2>
Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula

f is the force
m is the mass
From the question we have

We have the final answer as
<h3>6.67 m/s²</h3>
Hope this helps you

Answer:
Explanation:
6 waves in 12 seconds
The period of a wave is defined as the time taken by the wave to complete one oscillations.
Here, 6 waves are completed in 12 seconds
So, one wave is completed in 2 seconds
So, the period of the wave is 2 second.
frequency is defined as the number of waves completed in one second. It is the reciprocal of period of the wave.
frequency = 1 / 2 = 0.5 Hertz
Let the wavelength is λ.
f = 660 kHz = 660000 Hz
the relation for the wave speed and the wavelength and the frequency is given by
v = f λ
where v is the speed of wave = 3 x 10^8 m/s
So, 3 x 10^8 = 660000 x λ
λ = 454.55 m
Answer:
The speed of the kid and the skateboard together is 0.723 m/s
Explanation:
Let the mass of the kid be 
Let the mass of the skateboard be 
The initial speed of the skateboard, 
The initial horizontal speed of the boy as he jumps on the skateboard, 
Let the speed of the kid and the skateboard together be v
According to the principle of conservation of momentum:

Substituting the appropriate values into the given equation

36 = 49.8 v
v = 36/49.8
v = 0.723 m/s
