Answer:
2.2 x 10-19
Explanation:
Kinetic Energy = 1/2 m v ^2
The force of the air resistance is 4 N.
The given parameters;
- mass of the flower pot, m = 2 kg
- weight of the flower pot, W = 20 N
Let the air resistance = F
Apply Newton's second law of motion to determine the force of the air resistance acting upward to oppose the motion of the pot falling downwards.

Thus, the force of the air resistance is 4 N.

Work done = force x distance
work done = 15 x 3
work done = 45J
Answer:

Explanation:
Given data
Frequency f=90 Hz
To find
First three overtones of bassoon
Solution
The fundamental frequency of bassoon is found by substituting n=1 in below equation
f=v/λ=nv/2L

The first overtone of bassoon is found by substituting n=2
So
The second overtone of bassoon is found by substituting n=3
So

The third overtone of bassoon is found by substituting n=4
So
