Popular culture tells us that it’s very cold in space, but is that really true? on earth, most everyday objects cooldown by losing energy through conduction and convection. but in the vacuum of space, conduction and convection can’t happen, so the only way the international space station can lose heat is through radiation. exposure to rays from the sun, energy transfers from the machinery and the body heat from the astronauts themselves are continually heating up the space station, so how do they cool it down?
research the international space station and how its cooling system works.
how is waste heat removed from the space station? can you think of another way that this could be accomplished?
would you want to live and work aboard the international space station? why or why not?
what do you think would be the best thing about being on the international space station? what do you think would be the worst thing?

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
