Asteel ball has a diameter of 0.125 m. how much do you need to raise its temperature to make it expand by 0.000200 m (unit=c)?

The temperature raise is = 0.14 [C]

Explanation:

In order to find the temperature difference we must use the following equation:

But first we need to find the original volume V:

When the volume is increased the diameter will be larger:

D1 = 0.125[m] + 0.0002[m] = 0.1252[m]

Therefore the new radius will be:

r1=0.0626[m]

The new volume is:

Replacing all the calculated values in the equation:

given data:

determine the horse power (h.p) = ?

force applied to move the box(f) = 10 pounds,

box lifted from a distance         (d) = 3 feet

time taken to lift                         (t) = 10 sec,

the horse power is defined as amount of work required to move a load. the horse power is equal to 550 foot-pound per second

                  1 h.p   = 550 foot-pound/second

it can also be defined as the the load that need to be move a body for certain distance in a certain amount of time.

mathematically,

                      h.p = (force × distance)/ time

                            = (10 × 3)/ 10

                            = 30/10

                            = 3 foot -pound/sec

hence, the horse power is needed to move the box is 3 foot-pound/second

important note: 1 h.p = 550 foot-pound/second = 746 watts
