Answer: have a subject and a verb
Explanation:
Answer:
f = 8 %
Explanation:
given,
density of body of fish = 1080 kg/m³
density of air = 1.2 Kg/m³
density of water = 1000 kg/m²
to protect the fish from sinking volume should increased by the factor f
density of fish + density of water x increase factor = volume changes in water
1080 +f x 1.2 =(1 + f ) x 1000
1080 + f x 1.2 = 1000 + 1000 f
998.8 f = 80
f = 0.0800
f = 8 %
the volume increase factor of fish will be equal to f = 8 %

Answer:
The average power is 15.26 W.
Explanation:
Given that,
Force = 29 N
Radius = 0.27 m
Time = 1.9 s
We need to calculate the power
Using formula of power
Here,
Where, F = force
t = time
r = radius
Put the value into the formula
Hence, The average power is 15.26 W.
