Technician a says that the purpose of the starter relay is to complete the circuit from the battery to the starter motor. technician b says that the purpose of the solenoid is to complete the circuit from the battery to the starter motor. who is correct?

What is the force that opposes motion and works against the downward pull? a) friction b) gravity c) weight d) acceleration

What does si stand for,when referring to a system of measurement

Visualize the problem and identify special cases first examine the problem by drawing a picture and visualizing the motion. apply newton's 2nd law, ∑f⃗ =ma⃗ , to each body in your mind. don't worry about which quantities are given. think about the forces on each body: how are these consistent with the direction of the acceleration for that body? can you think of any special cases that you can solve quickly now and use to test your understanding later? one special case in this problem is if m2=0, in which case block 1 would simply fall freely under the acceleration of gravity: a⃗ 1=−gj^.
