Compare the amount of work done when one man uses an ideal pulley to lift a 500 newton weight 2 meters and one man lifts a 500 n
Liono4ka [1.6K]

More work is done when one man lifts the weight using a pulley. Option C is correct.

<h3>What is mechanical advantage ?</h3>

Mechanical advantage is a measure of the ratio of output force to input force in a system, it is used to obtained efficiency of  forces in levers and pulley.

It is an effective way of amplify the force in simple machines like lever  The theoretical mechanical advantage is defined as the ratio of the force responsible for the useful work in the system  to the applied force.

More work is done when one man lifts the weight using a pulley. With the pulley, the mechanical advantage is increasing.

Hence, option C is correct.

A student stretches an elastic band by 0.8 m in 0.5 seconds. The spring constant of the elastic band is 40 N/m. What was the pow
miv72 [106K]

Answer:

The power exerted by the student is 51.2 W

Explanation:

Given;

extension of the elastic band, x = 0.8 m

time taken to stretch this distance, t = 0.5 seconds

the spring constant, k = 40 N/m

Apply Hook's law;

F = kx

where;

F is the force applied to the elastic band

k is the spring constant

x is the extension of the elastic band

F = 40 x 0.8

F = 32 N

The power exerted by the student is calculated as;

P = Fv

where;

F is the applied force

v is velocity = d/t

P = F x (d/t)

P = 32 x (0.8 /0.5)

P = 32 x 1.6

P = 51.2 W

Therefore, the power exerted by the student is 51.2 W

Convert the Celsius temperature of the surface of the sun, which is
Ghella [55]
So,

The conversion factor is:

F = C *  \frac{9}{5} + 32

So, if we plug in the numbers, we get:
F = 5500 *  \frac{9}{5} +32

Multiply
\frac{5500}{1} * \frac{9}{5} = 9900

Add 32
9900 + 32 = 9932

5500 degrees Celsius = 9932 degrees Farenheit.
