Starting from rest, a 75.0-kg snowboarder slides straight down a 115-m slope in 6.6 s. if the slope is a 35°
incline, find the following:
(a) the acceleration of the snowboarder.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

An ideal gas is held in a container at constant volume. initially, its temperature is 5 degrees c and its pressure is 1.2 atm. what is its pressure when its temperature is 43 degrees c? answer in units of atm

Which accounts for an increase in the temperature of a gas that is kept a constant volume
