A toy car is traveling down a small ramp. While it is at a height of 0.4 m, it is traveling down the ramp at 2.2 m/s (ignore friction and air resistance, and assume that the bottom of the ramp has a height of 0 m). What is the speed of the car when it reaches the bottom of the ramp? (Correct about 3.5 m/s.)

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

What is the magnitude of the acceleration vector which causes a particle to move from velocity −5i−2j m/s to −6i+ 7j m/s in 8 seconds. answer in m/s.

While standing outdoors one evening, you are exposed to the following four types of electromagnetic radiation: yellow light from a sodium street lamp, radio waves from an am radio station, radio waves from an fm radio station, and microwaves from an antenna of a communications system. rank these type of waves in terms of increasing photon energy.
