An electrical generator and motor are two machines that operate oppositely.


An electrical generator uses mechanical energy, converting it to produce electrical energy. This mechanical energy is provided in most cases from a spinning/rotating action in which a wire or loop of wire spins in a magnetic field. This causes the wire to move sharply through the magnetic field, causing current to flow, and in turn, creating electricity.


An electrical motor does the opposite, but uses the same principles, converting electrical energy to produce mechanical energy. The motor will have an alternating current (AC) moving through pairs of magnets, producing a rotating magnetic field. This causes the motor's central rotor to spin, powering whatever machinery it is hooked up to.

mojhsa [17]

Answer:

Isabella will not be able to spray Ferdinand.

Explanation:

We'll begin by calculating the time taken for the water to get to the ground from the hose held at 1 m above the ground. This can be obtained as follow:

Height (h) = 1 m

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =.?

h = ½gt²

1 = ½ × 9.8 × t²

1 = 4.9 × t²

Divide both side by 4.9

t² = 1/4.9

Take the square root of both side

t = √(1/4.9)

t = 0.45 s

Next, we shall determine the horizontal distance travelled by the water. This can be obtained as follow:

Horizontal velocity (u) = 3.5 m/s

Time (t) = 0.45 s

Horizontal distance (s) =?

s = ut

s = 3.5 × 0.45

s = 1.58 m

Finally, we shall compare the distance travelled by the water and the position to which Ferdinand is located to see if they are the same or not. This is illustrated below:

Ferdinand's position = 10 m

Distance travelled by the water = 1.58 m

From the above, we can see that the position of the water (i.e 1.58 m) and that of Ferdinand (i.e 10 m) are not the same. Thus, Isabella will not be able to spray Ferdinand.
