A worker is holding a filled gas cylinder Weil which two sentences are true about the energy of the filled gas cylinder 1. It has no energy because it’s being held still.
2. It has gravitational potential energy because of its height.
3. It’s atoms and molecules have thermal energy.
4. It has motion cause it will fall if let go.
5. It’s kinetic energy is being converted to potential energy.

In the circuit, the switch s has been open for a long time and r = 125 kohm. it is then suddenly closed. (a) determine the time constant before the switch is closed. s (b) determine the time constant after the switch is closed. _ s (c) let the switch be closed at t = 0. find the current in the switch as a function of time. (use t for time. express your answer in milliamps and seconds.) i(t) =_

If a rock is thrown upward on the planet mars with a velocity of 10 mys, its height in meters t seconds later is given by y − 10t 2 1.86t 2 . (a) find the average velocity over the given time intervals: (i) [1, 2] (ii) [1, 1.5] (iii) [1, 1.1] (iv) [1, 1.01] (v) [1, 1.001] (b) estimate the instantaneous velocity when t − 1.
