consider the picture of slinky. the transverse wave is transporting energy from left to right. the particles of the medium will

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^.

Suppose you hit your hand against the edge of table. using newton’s third law of motion why does my hand hurt? explain

The energy of a photon is equal to (what) times (what) of the photon.
