The correct equation for Ohm’s Law is . I know this is correct because Voltage and current have a (positive/ negative) relationship. In the current vs. voltage graph shown below, it is clear that as voltage (increases/ decreases) it stays constant so does current. When voltage was , the current was only Amps. As voltage moved up to and , current increased to and . As voltage (increases / decreases / stays constant), current (increases / decreases / stays constant) as well. Therefore, voltage must be in the numerator of the equation. Additionally, resistance and current have a (positive / negative) relationship. In the current vs. resistance graph shown below, it is clear that as resistance (increases / decreases / stays constant), current (increases / decreases / stays constant). When resistance was at Ohms, current was Amps. But, as resistance increased to and Ohms, current decreased to A and

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

explanation:

bc its just b

the force on the thing and the distance the force moves the thing

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
