A frictionless cart of mass 10kg has a force of 30N applied to it for just 1 minute. How fast will the cart be going at 30 sec

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

The frequencies refer to the sample data collected from a population of interest when performing a hypothesis test comparing two or more population proportions.

A10nc charge sits at a point in space where the magnitude of the electric field is 1500 n/c. what will the magnitude of the field be if the 10 nc charge is replaced by a 20 nc charge? assume the system is big enough to consider the charges as small test charges.
