Answer:
4
Explanation:
you have to divide the velocity by time so 40 divided by 10 and the answer should be 4

Answer:
e) 0.099
Explanation:
For an adiabatic expansion:
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
is the adiabatic index (which is 
for an ideal monoatomic gas
In this problem, we have
since the volume increases by a factor 4
We can re-write the equation to find by what factor the pressure changes:
When wind turns the blades of a wind turbine and then this energy is used to power homes, this is an example of an energy transfer from mechanical to electrical energy.
<h3>What is Wind power?</h3>
- In order to produce electricity, wind turbines are mostly used in wind power or wind energy.
- In comparison to burning fossil fuels, wind energy is a well-liked, environmentally friendly, renewable energy source.
- Wind energy, like all other forms of energy production, has the potential to have negative effects on the environment, including the loss, fragmentation, or degradation of habitat for animals, fish, and plants.
- Additionally, flying animals like birds and bats could be harmed by turbine blades that are in motion.
- Wind energy is economical.
- After the production tax credit, land-based utility-scale wind is one of the least expensive energy sources on the market at 1-2 cents per kilowatt-hour.
