8. The velocity of waves on an ocean of density p is written as v = Ag* pº 22,
where A, x, y,z are constant, g is the
acceleration due to gravity and á is the
wavelength of
the wave. Using
dimensional analysis, find the exact value
of x, y, and z [JUPEB]

Modify the equation fδt=δ (mv) to find the force of friction.

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

Unpolarized light whose intensity is 1.19 w/ is incident on a polarizer. (a) what is the intensity of the light leaving the polarizer? (b) if the analyzer is set at an angle of = 41.0∘ with respect to the polarizer, what is the intensity of the light that reaches the photocell?
