Because the waves in the water with the fan like system.
Answer:
a) 6.4 x 10^-12 cm^3
b) 17 x 10^-6 mm^2
Explanation
a). The shape is assumed to be spherical The volume = volume of a sphere = \frac{4}{3} \pi r^3

= 6.3715 μm^3
1 μm^3 = 10^-12 cm^3
6.3715 μm^3 = 6.3715 x 10^-12 cm^3
==> 6.4 x 10^-12 cm^3
- Displacement = 10 m
- Time = 5 s
- We know,

- Therefore, the car's velocity

<h3>Answer:</h3>
The car's velocity is 2 m/s.
Hope you could get an idea from here.

Answer:
0.26seconds
Explanation:
Impulse is the product of force and time
Impulse =Force * Time
Given
Impulse = 67Ns
Force = 257N
Required
Time
From the formula;
Time = Impulse/Force
Time = 67/257
Time = 0.26s
Hence the amount of time is 0.26seconds
