When you push a door closer to the hinges, why does it open more slowly? because you are closer to the center Now choose from one of the following options Why? a) It opens slowly, because the lever arm is shorter so the torque is large b) It opens slowly because the lever am is longer so the torque is large. c It opens slowly, because the lever asi is shorter so the torque is less. Comes from 9.2 The...

Imagine making a heavy door swing open by giving it a brief hard push. First, you push at its center, "push I " in the diagram Then you push near the edge, "push 2." Both pushes are equally hard akd last the same time. Which push is more effective at making the door swing open? Why? Again, lets compare the effectiveness of two pushes. This time, both pushes are applied to the same spot on the door. But...

Why is the answer E and not
A?
19. When opening a door, you push with a force with magnitude F and which is directed perpendicularly to the door. If you apply the force closer to the hinges of the door.. A. the torque you exert and the angle the door moves through for a given distance which your B. the torque you exert will be larger, but the angle the door moves through for a given distance C. there...

You should feel a slight resistance when you try to push and pull the electromagnet into the coil. Where does this come from and what is the direction of this force? Why did it become harder to move the magnet into the coiled loop of wire as more wires were added, as you moved the magnet faster, or as the area of the loop was bigger?

You are pushing against a door while your body is slanted. The door is made of smooth ice and has zero friction. The floor though, is made of rough sandpaper and has coefficients of friction μs and μk, both of which are non-zero. Model yourself as a uniform one-dimensional rod of mass M and length L. Your body makes angle θ relative to the ground. You know: M, L, θ, μs, μk, g (also remember that there is no friction...

Project 1. Dog Door You are asked to create a dog door for a client. You are programming the remote that will do things such as open and close, etc. You must create both the program and write a white paper explaining your design • It should open (saying "The dog door is open.") and close (saying "The dog door is closed.). • It should take into account a dog going outside and coming back in; it should open when...

Help me ... THANKS You are trying to open a safe. It has a knob that you can turn in small steps. Above the knob is a number which changes as you turn the knob. Experimentation shows that the number increases for each step you turn the knob clockwise, and decreases for anti-clockwise. The numbers go from 0 to 37. There is also a handle to open the door. You are given the following instructions to open the safe: 1....
