Answer: The Propellant fraction is 0.87.
The payload fraction is 0.04.
Δv = 8991.81 m/s
Explanation: To determine the fractions, first, calculate the total mass of the rocket:
The Propellant Fraction will be
0.87
The Payload Fraction is:
0.04
The value of Δv is calculated by the formula:
Δv =
The exhaust velocity () is:
9.81*450
4414.5
is the total mass after the rocket consume all the propellant and
is the total mass before the action.
Δv =
Δv =
Δv = - 4414.5.ln(0.13)
Δv = 8991.81
Δv will be 8991.81 m/s.
Answer:
hydropower
Explanation:
hydroelectric power is a domestic source of energy. This automatically allows each state to produce their own energy without being reliant on international fuel sources. It also won't pollute the air like power plants that burn fossil fuels, such as coal or natural gas. This is because it is powered by water.
