When a charged capacitor is connected to earth, it discharges and the voltage v across it will decrease according to the equation:
dv/dt=−v/rc
where r (the resistance) and c (the capacitance) are constants. if the voltage v across a certain capacitor with capacitance c = 3×10−6 farads
drops from 10 volts to 1 volt in two seconds, determine the resistance r.

Will give brainliest! jay rides his 2.0-kg skateboard. he is moving at speed 5.8 m/s when he pushes off the board and continues to move forward in the air at 5.4 m/s. the board now goes forward at 13 m/s.a. determine jay’s mass.b. determine the change in the internal energy of the system during this process.(express your answer to two significant figures and include the appropriate units.)

Use the ratio form of kepler’s third law, = , and the data provided to determine the time it takes mars to orbit the sun. round your answer to the nearest tenth. earth’s orbital period = 1.0 earth year earth’s distance from the sun = 1.0 au mars’s distance from the sun = 1.5 au it takes mars about ⇒ 1.8 earth years to orbit the sun.
