The position of a car as a function of time is given by x= (50m) + (-5.0 m/s)t + (-10 m/s2)t2(a) What are the initial position, initial velocity, and acceleration of the car? (b) plot x versus t for t=0 to t=2 s (c) What distance does the car travel during the first 1.0 s? (d) What is the average velocity of the car between t=1.0 s and t=2.0 s?

Which statement is true for light passing into a medium that is more optically dense than the first medium through which it past

What happens in a global convection cell

The solar panels used by mark function because of the photoelectric effect. light shines on the cells causing electrons to be ejected from the metal, which produces an electric current. at night on mars, no light will fall on the solar cells and no electric current will be generated. according to your notes, what type of light is typically needed to cause the photoelectric effect? a)visible b)ultraviolet c)infrared
