The net force on a 925 kg car is 125 n as it pulls away from a stop sign. find the car’s acceleration.

0.135 ms⁻²

Explanation:

By Newton's 2nd law,

The rate of change of momentum is directly proportional to the unbalance force applied on the object,

By that you can get the equation,

F = ma ⇒ a = F/m

where terms are in usual meaning

a = 125/925 = 0.135 ms⁻²

wire in brush may conduct electricity from cell to drill and vice versa electrc shock possible

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
