The greenhouse effect can be explained easily if you understand the laws of blackbody radiation. a greenhouse gas blocks the transmission of infrared light. given that the incoming light to earth is sunlight with a characteristic temperature of 5800 k (which peaks in the visible part of the spectrum) and the outgoing light from earth has a characteristic temperature of about 300 k (which peaks in the infrared part of the spectrum), explain how greenhouse gases cause earth to warm up. as part of your answer, discuss that greenhouse gases block both incoming and outgoing infrared light. explain why these two effects don’t simply cancel each other, leading to no net temperature change.

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

f=ma a/f/m a= 480/60 a = 8m/s/s that is quick wow
