Answer:
2:5
Explanation:
We have the initial mass of the fish = 4.5kg
The mass of water intake = 40%of 4.5kg
= 0.40x4.5kg
= 1.8kg
The formula for conserving momentum
M1V1 = M2V2
M1 = mass of the puffer fish = 4.5kg
M2 = mass of the applied water = 1.8kg
V1 = velocity of the puffer fish
V2 = velocity of water
We are then to find v1/v2
V1/V2 = M2/M1
V1/V2 = 1.8/4.5
= 1/2.5
This is also 2/5
Therefore we have the ratio to be 2:5

Answer:
ATP and NADPH
Explanation:
ATP represents the chemical energy that is obtained from light (luminous energy).
NADPH represents the reducing power that will be used to reduce CO2 in the Calvin cycle
The work done by the engine is equal to the gravitational potential energy (GPE) put into it. GPE = mgh
GPE = Work = 1200·9.81·13 = 153,036J
