Aperson weighing 900 n is standing on snowshoes. each snowshoe has area 2500 cm^2. what is the pressure exerted by each individual snow shoe on the snow?

a) 0.18 n/m^2
b) 0.36 n/m^2
c) 1800 n/m^2
d) 3600 n/m^2

is it 3600 n/m^2?

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e

Light from two different sources are incident upon the same side of a polarizing filter. light from one source is polarized with total intensity ip, while light from the other source is unpolarized with total intensity iu. as you rotate the polarizing filter through 360 degrees, the intensity of the transmitted light on the other side varies by a factor of 9. what is the relative intensity of the initial polarized source to the unpolarized source, or ip/iu?
