(recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm Physics, 22.06.2019 01:30, chandranewlon
Ablock of mass 1.5 kg slides down an inclined plane that has an angle of 15. if the inclined plane has no friction and the block starts at a height of 3 m, how much kinetic energy does the block have when it reaches the bottom? acceleration due to gravity is g = 9.8 m/s2. a. 6.8 j b. 50.9 j c. 0 j d. 44.1 j Physics, 22.06.2019 02:30, ntangpricha

Abeam of partially polarized light can be considered to be a mixture of polarized and unpolarized light. suppose we send such a beam through a polarizing filter and then rotate the filter through 360 degrees while keeping it perpendicular to the beam. if the transmitted intensity varies by a factor of 4.1 during the rotation, what fraction of the intensity of the original beam is associated with the beam's polarized light?
Do you know the correct answer?
