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.)

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
