Worried that your cat may be ambushed by a mountain lion, you build a fence around your backyard that is 4 m tall. If a mountain lion approaches the fence and leaps at an
angle of 45°, what must its initial speed be to reach the top of the fence?

Picture a all traveling at a constant speed around the inside of a circular structure. is the ball accelerating? explain your answer

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

In the circuit shown below, with each bulb holding a resistance of 60 ohms, how many amps of current are flowing? express your number as a decimal.
