Answer:

Divide by 1000

Explanation:

As stated in the name, a Kilowatt is 1000 watts. So let's say you have 200 watts and you need them in kW. Since 1kW=1000W, we need to divide 200/1000 to get 200/1000=0.2kW

GrogVix [38]

Answer: In a battery, voltage determines how strongly electrons are pushed through a circuit, much like pressure determines how strongly water is pushed through a hose. Most AAA, AA, C, and D batteries are around 1.5 volts. Imagine the batteries shown in the diagram are rated at 1.5 volts and 500 milliamp-hours.

Explanation: Today "AA" is frequently used as a size designation, irrespective of the battery's electrochemical system. The main numbers used for the most common NiMH and NiCad battery

A cheetah is known to be the fastest mammal on Earth, at least for short runs. Cheetahs have been observed running a distance of
Arlecino [84]

The cheetah needs 197.8 seconds to complete the 5.50 *100 m distance.

The distance traveled divided by the time taken is the most popular formula for calculating average speed. The average speed is determined by dividing the whole distance by the total time required to complete the distance. The other calculation, provided you have the initial and final speeds, adds them together and divides by 2.20. calculating the time needed for a cheetah to travel 5.50 102 meters.

10 km/h average speed is equal to 10 / 3.6, or 2.78 m/s.

Dist. = 5.50 102

Time =?

average speed = time / distance

time=5.50 x 100/ 2.78

Time = 197.8 s

Therefore, it takes a cheetah 197.8 seconds to travel 5.50 102 meters.

Answer:

The magnitude of force exerted on the handle is 108.73 N

Explanation:

To determine the magnitude of force exerted, we will use the formula relating Power and Force.

Power is the rate at which work is done. Power can be calculated from the formula

Power = Work / Time

But, Work = Force × Distance

Hence,

Power is given by the formula

P = \frac{F \times s}{t}

Where P is the Power

F is the force

s is the distance

and t is the time

From P = \frac{F \times s}{t},

Then we can write that

F = \frac{P \times t}{s}

From the question,

Distance, s = 1.1 m

Time, t = 1.3 s

Power, P = 92 W

Putting these values into the formula, we get

F = \frac{92 \times 1.3}{1.1}

F = \frac{119.6}{1.1}

F = 108.73N

Hence, the magnitude of force exerted on the handle is 108.73 N.
