Eeg voltage is: select one: a. flow of electrons through a pathway and the unit is the ampere b. a measure of the opposition to the flow of alternating current and the unit is the ohm c. a measure of the resistance of a material to the flow of direct current and the unit is the ohm d. the potential charge difference between two points and the unit is the volt

The answer is d. The potential charge difference between two points and the unit is the Volt

Explanation:

The voltage is the difference in electric charge between two points that pushes electrons along the circuit from the highest charged (positive) pole to the lowest charged (negative) .

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
