Jane built a roller coaster. To test it, she used a marble with a mass of .025 kg and a diameter of .019 m. As it passed through the photogate at point B she recorded the time to be .0038 seconds. Using this information above, answer the following questions. Answer each question separately.

A500g object falls off a cliff and losers 100 j from its gravitational potential energy store. if the gravitational field strength g=9.8n/kg, how high is the cliff?

Avery long solenoid of inner radius 2.75 cm creates an oscillating magnetic field of the form = for this solenoid, =0.00425 t and =319 rad/s. (a)what is the maximum value of the induced electric field at a perpendicular distance 1.45 cm from the axis of the solenoid? (b) what is the maximum value of the inducted electric field at a point 5.85 cm perpendicular from the axis of the solenoid?
