Gravitational potential energy -> Kinetic energy -> Mechanical energy -> Electrical energy.

The water starts up (potential) and flows down (kinetic), the flowing water turns a big wheel (mechanical) which creates electricity (electrical).

Answer:

gravitational potential energy into kinetic energy into mechanical energy into electrical energy

Explanation:

Hydroelectric dam is used to convert gravitational potential energy stored in water to electrical energy. The water is stored at a height. As the water is releases, the gravitational potential energy converts to kinetic energy. The water is allowed to strike the turbine which starts rotating. Thus, kinetic energy is converted to mechanical energy. The turbine is connected to generator where mechanical energy is converted to electrical energy.

Thus, the correct sequence of energy transformation is: gravitational potential energy into kinetic energy into mechanical energy into electrical energy

A boy starts from point A and walks 3 meters toward the north, then turns around and walks 6 meters toward the south.

docker41 [41]

Answer:

Total distance traveled = 9 m

Explanation:

Given:

Distance travel towards north = 3 meter

Distance travel towards south = 6 meter

Find:

Total distance traveled

Computation:

Total distance traveled = Sum of total distance

Total distance traveled = Distance travel towards north + Distance travel towards south

Total distance traveled = 3 m + 6 m

Total distance traveled = 9 m

There is a species of bamboo that can grow 36 inches per day. If a plant grew at this rate and was measured at 40 inches initial

LekaFEV [45]

Answer:

It will take the plant $4\frac{4}{9}$ days or 4.44 days to grow to a height of 200 inches tall.

Explanation:

From the question, the rate at which the species of the bamboo tree grows is 36 inches per day.

To determine how long it would take a plant 40 inches tall initially to grow at this rate (that is, 36 inches per day) to a height of 200 inches.

This means we will calculate the number of days it will take the plant to grow additional 160 inches ( 200 inches - 40 inches) at this rate.

Now,

If the plant grows 36 inches in 1 day

then it will grow 160 inches in x days

x = (160 inches × 1 day) / 36 inches

x = 160 / 36

x = $4\frac{4}{9}$ days or 4.44 days

Hence, it will take the plant $4\frac{4}{9}$ days or 4.44 days to grow to a height of 200 inches tall.
