A 120 W lightbulb and a 90.0 W lightbulb are connected in a series. If the voltage applied across the combination is 100 V, what is the current through the two bulbs?
As a result of the distribution illustrate what is scotts basis in the a/r and land, and explain how much gain or loss does he recognize?
A skateboarder shoots off a ramp with a velocity of 6.80m/s, directed at an angle of 59° above the horizontal. The end of the ramp is 1.10 m above the ground.
A +3.07 nC point charge is placed at one corner of a square (1.90 m on a side), and a -6.51 nC charge is placed on the corner diagonally opposite. What is the magnitude of the electric field at either of the other two corners?
