Here's what the diagram looks like.

Homework Statement A ping pong ball of mass 3.0 x 10^-4 kg hangs from a light thread 1.0m long, between 2 vertical parallel plates 10.0cm apart. When the potential difference across the plates is 420 V, the ball comes to equilibrium 1.0 cm to one side of its original position. a) Calculate...

Oh I forgot to put that the new antenna is 8.12km from the house. So if d = m(lambda) its constructive interference and if d just doesn't = m(lambda) then its destructive interference?

Homework Statement The transmitting antenna for a radio station is 7.00km from your house. The frequency of the electromagnetic wave broadcast is 536kHz. The station builds a 2nd transmitting antenna that broadcasts an identical em wave in phase with the 1st one. The new antenna is 8.12km from...

Homework Statement A bullet is shot horizontally into a block suspended by two strings. The bullet remains embedded in the wood and the wood and bullet together suspend upward. a) Explain why the horizontal momentum of the bullet-wood system is conserved during the collision even though the...

Newton's third law says that for every action force there's a simultaneous reaction force equal in magnitude to the action force, but in the opposite direction. So doesn't that make the net force zero? If that's true how does anything move?

There's something else I'm confused about though with Newton's laws. Newton's third law says that for every action force there's a simultaneous reaction force equal in magnitude to the action force, but in the opposite direction. If that is true, then doesn't that make the net force zero? If...

Yeah they're right and I get it now thanks!

Ya that's what I meant, I just messed up typing it >_>

So T(right) - 12N = 9.8208N T(right) = 21.8 Because the net force i just T(right) = T(left) right?

The force on the left is 12.0N the force on the right is 32.955N so the net force is 32.955N - 12N = 23.13N?

The mass of the 2nd cart is 13.2kg and its acceleration is 0.744m/s squared.

F = (16.1 + 13.2) (0.744) = 11.98N Is that how you do it?

Yeah
