Elements that are in period ONE
Has ___ electron shells

1

Explanation:

Theres only one element in period one, and that is hydrogen. it has one proton, meaning it also has only one electron. This is one way to help you find the answer.

you can also find it by looking at the number beside it, that number is the amount of shells on the atom (Arrow pointing at it in the image below)

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

the higher the current the higher the mag field around it the higher the influence on the compass
