A 10 kg box is sliding up a hill at 6 m/s. If it loses 100 Joules of energy because of friction, how high up the hill does the box go before stopping? With how you got the answer please

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?

In order of decreasing light-transmitting capabilities of materials, which is the correct sequence? a. transparent -> translucent -> opaque b. opaque -> transparent -> translucent c. opaque -> translucent -> transparent d. translucent -> transparent -> opaque

Me ! since green bounces off red, this must be collision a.elastic b.explosion c.inelastic
