Answer:
Explanation:
The mass of the man can be found by using the formula
f is the force
a is the acceleration
From the question we have
We have the final answer as
<h3>50 kg</h3>
Hope this helps you
1. friction between water molecules
2. the wave spreads out onto a larger and larger area, so per unit area, the energy of the wave goes down
I think its all four of them could be wrong but try all four !!!!!!
It's hard to tell exactly what's happening in that 110 cm that you marked over the wave. What is under the ends of the long arrow ? How many complete waves ? I counted 4.5 complete waves ... maybe ?
If there are 4.5 complete waves in 110cm, then the length of 1 wave is (110/4.5)=24.44cm.
Frequency = speed/wavelength
Frequency = 2m/s /0.2444m
Frequency = 8.18 Hz
