Ahorse began running due east and covered 25km in 4.0hr. what is the average velocity of the hourse?

The correct answer is 6.25 km per hour due east.

Explanation:

We are given that a horse is running due East and covers a distance of 25 kilometers in a time period of 4 hours and we are supposed to find its velocity.

The formula of velocity is similar to speed which is the ration of distance and time.

Velocity = distance / time

So putting in the given values to find the velocity of the horse:

V = 25 / 4

V = 6.25 km / hour

the minimum amperage that the current in this wire would have to have so that its weight is completely supported by the magnetic force due to earth's field, assuming that no other forces except gravity act on it

i really dont know but i will try okay.

so i think u would just add all them up and get your answer..
