A flashlight bulb is connected to a dry cell of voltage 4.50 V. It draws 15.0 mA (1000 mA = 1 A). Its resistance is (5 points) 2.5 E2 ohm 3.0 E2 ohm 3.5 E2 ohm 4.0 E2 ohm 4.4 E2 ohm

Two polarizers are oriented at 40∘ to each other and plane-polarized light is incident on them. if only 16 percent of the light gets through both of them, what was the initial polarization direction of the incident light?

An open cart is moving along a straight frictionless horizontal track. when rain starts falling vertically into the cart, what happens to the speed of the cart?

Awater slide of length l has a vertical drop of h. abby's mass is m. an average friction force of magnitude f opposes her motion. she starts down the slide at initial speed vi. use work-energy ideas to develop an expression for her speed at the bottom of the slide. then evaluate your result using unit analysis and limiting case analysis. express your answer in terms of the variables h, m, l, vi, f and appropriate constants. vf v f
