A32.5-kg rock is traveling at a constant velocity through space. then a force of 140 n is exerted on the rock. what acceleration does the force produce? 3.31 m/s^2 2.32m/s^2 4.31 m/s^2 45.5 m/s^2 10.7 m/s^2

As per Newton's II law we can say force applied on an object is product of mass and acceleration

given that

Force = 140 N

mass = 32.5 kg

now we can use above formula

so its acceleration must be 4.31 m/s^2

an energy transformation flow diagram is shown

where is it ?

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
