Three resistors of 5 ohms, 10 ohms and 20 ohms are connected in parallel across a 12-v supply. Calculate, i) the combined resistance (ii) the current flowing through each resistor (iii) the total current in the circuit (iv) the electrical power dissipated in through each resistor

Ablue car pulls away from a red stop-light just after it has turned green with a constant acceleration of 0.5 m/s 2 . a green car arrives at the position of the stop-light 6.5 s after the light had turned green. if t = 0 when the light turns green, at what time does the green car catch the blue car if the green car maintains the slowest constant speed necessary to catch up to the blue car? answer in units of s.
