Answer:dam D: fall height of 100 feet

dam D: fall height of 100 feet

dam C: fall height of 135 feet

dam A: fall height of 175 feet

dam B: fall height of 75 feet

Explanation:

Four rivers have the same volume of water flow over time but fall from different heights to power hydroelectric dams. The dam would provide the most hydroelectric power that have maximum height that is 175 feet.

What is hydroelectric power?

Using the rise or fall of water, hydroelectric power is generated. For instance, a large, swiftly running river has a lot of moving energy that generates enough water pressure to turn a turbine's blades and power an electric generator. The same water pressure can be produced by letting water fall from a tremendous height. To create water pressure, we store water and raise it to tremendous heights using dams. Dams are among the largest man-made constructions ever constructed.

Power = Water Flow Rate × Acceleration Due to Gravity × Reservoir Height × Coefficient of Efficiency

So if we increase the height than power increases. Maximum height have maximum power.

What is the average speed of a helicopter that flies 50 km in 20 minutes and then 30 km in 10 minutes?

Answers

Answer:

160 km/hour

Explanation:

Average speed = Total distance traveled/Total time taken

Total distance traveled = 50 + 30 = 80 km

Total time taken = 20 + 10 = 30 min

Average speed = 80/30 = 8/3 km/min = 8/3 x 60 km per hour

= 160 km/hour

An object changing its speed from 10 m/s to 3 m/s is undergoing
_____ acceleration.

Answers

Negative acceleration. Deceleration
It is because acceleration formula is final speed subtract initial speed.
The initial speed is more bigger than its final speed.
So, it is negative acceleration or deceleration.

Deceleration because it is decreasing
