1. Right A stationary object lies along the
line connecting two spheres. The
object is exactly in between the
two spheres (the distances from
the centers of each sphere to the
object are identical).
2. Left
3. Does not mov
4. Down
The left sphere is a hollow
spherical shell of mass M and the
right sphere is a solid sphere of
mass M. Which direction will the
object move?? Note the object is
outside of both the spheres.
5. Up

Arock is dropped from a cliff and reaches the ground in 2.70s. at the same time another rock is thrown horizontally from the same height with initial x velocity of 0.95 m/s. what distance will in x will the second rock cover?

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?

Why does gravity have a lesser than grater effect on higher altitudes?
