Like my MS Paint skills? :)
The image shows a section of an alpine cable-car system. The maximum permissible mass of each car with occupants is 2800 kg. The cars, riding on a support cable, are pulled by a second cable attached to each pylon (support tower); assume the cables are straight. What is the difference in tension between adjacent sections of pull cable if the cars are at the maximum permissible mass and are being accelerated up the 35 degree incline at 0.81 m/s^2 ? Could you explain?

Two separate but similar oils of wire are mounted close to each other. The first is connected to a battery and has a direct current flowing through it. The second is connected to a galvanometer. How does the galvanometer respond when the switch in the first circuit is closed? How about after being closed when the current is steady? And what about when the switch is opened?


*This is for my physics class.....I'm SO confused! If someone could explain it in easily-understandable terms, i would greatly appreciate it!

i dont want the answer obviously, just a step in the right direction! because my friend has NO IDEA how to do it (and either do i because i havent taken physics yet lol)

Thank u!!!!

A tennis ball with a speed of +11.3 m/s is thrown perpendicularly at a wall. After striking the wall, the ball rebounds in the opposite direction with a speed of 8.99 m/s. If the ball is in contact with the wall for 0.0124 s, what is the average acceleration of the ball while it is in contact with the wall?
