Q. A circuit contains six 205 ohm lamps with 60-W bulbs and a 9 ohm heater connected in parallel. the voltage across the circuit is 120 V.what is the current in the circuit when four lamps are turned on?
Q. A particle leaves the origin with an initial velocity v = (4.00 ihat) m/s and a constant acceleration a = (-2.00 ihat - 0.700 jhat) m/s2
What is the velocity of the particle when it reaches its maximum x coordinate?
