A truck is travelling at 30km/hr with engine delivering a driving force of 800n to the road Calculate the power developed and the work done in 25 seconds

Alex needs to determine the power dissipated in a resistor. She measures the current through the resistor to be I=10.0±0.6 A, and its resistance to be R=45.0±2.0 Ω.

Describe each type of item tested in terms of its V vs I being "Ohmic" or not. Use one sentence per item-type tested. Item types tested are Resistors, Coil, Diode, Capacitors, and Light Bulb.

If you place 0◦C ice into 0◦C water in an insulated container, what will the net resultbe? Will there be less ice and more liquid water, or more ice and less liquid water, orwill the amounts stay the same? Explain.

At what speed would a car have to move in order to travel 20 kilometers in two hours?

Find the equivalent resistance Req between terminals a and b if terminals c and d are open and again if terminals c and d are shorted together. (Round the final answers to two decimal places.) With terminals c-d open, Req = Ω.
