Turner’s treadmill starts with a velocity of −3.0 m/s and speeds up at regular intervals during a half-hour workout. After 33 min, the treadmill has a velocity of −6.7 m/s. What is the average acceleration of the treadmill during this period? Answer in units of m/s^2

Explanation:

Acceleration is change in velocity over change in time.

a = Δv / Δt

a = (-6.8 m/s − (-3.0 m/s)) / (33 min × 60 s/min)

a = (-3.8 m/s) / (1980 s)

a = -0.0019 m/s²

i don't understand is there any other way you can rephrase it plz let me know in the comments and i will do it.

explanation:

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
