Consider a refrigerator that consumes 320 W of electric power when it is running. If the refrigerator runs only one quarterof th
ryzh [129]

Answer:

$5.184

Explanation:

The cost can be calculated using the formula: Cost = Load \ factor \times Number \ of \ hours \ \\M_{month} = M_{units} \times W\\

Before using this, we require the following conversions:

<em>320 W → kW:</em>

\frac {320}{1000} = 0.32

<em>30 Days → Hours:</em>

30 \times 24 = 720

Using the above stated formula:

M_{month} = 0.09 \times 0.32 \times \frac{1}{4} \times 720 = 5.184

A 10 hp motor is used to raise a 1000 Newton weight at a vertical distance of 5 meters. What is the work the motor performs?
Aleksandr [31]

The work done by a 10 HP motor when it raises a 1000 Newton weight at a vertical distance of 5 meters is <u>5kJ</u>.

Define work. Explain the rate of doing work.

Work is <u>the energy that is moved to or from an item by applying force along a displacement</u> in physics. For a constant force acting in the same direction as the motion, work is <u>easiest expressed as the product of </u><u>force </u><u>magnitude and distance traveled</u>.

Since the <u>force </u><u>transfers one unit of energy for every unit of </u><u>work </u><u>it performs</u>, the rate at which work is done and energy is used are equal.

Solution Explained:

Given,

Weight = 1000N and distance = 5m

A/Q, the work here is done in lifting then

Work = (weight) × (distance moved)

         = 1000 X 5

         = 5000Nm or 5000J = 5kJ

Therefore, the work done in lifting a 1000 Newton weight at a vertical distance of 5 meters is 5kJ.
