Two objects, x and y, move toward one another and eventually collide. object x has a mass of 2m and is moving at a speed of 2vo to the right before the collision. object y has a mass of m and is moving at a speed of vo to the left before the collision. which of the following describes the magnitude of the forces f the objects exert on each other when they collide?

a. the force exerted by x on y is 4f to the right, and the force exerted by y on x is f to the left.
b. the force exerted by x on y is 2f to the right, and the force exerted by y on x is f to the left.
c. the force exerted by x on y is f to the right, and the force exerted by yon x is f to the left.
d. the force exerted by x on y is f to the left, and the force exerted by y on x is f to the right.

The intensity of a polarized electromagnetic wave is 12 w/m^2. part a) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=0∘ with the plane of polarization? part b) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=30∘ with the plane of polarization? part c) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=45∘ with the plane of polarization? part d) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=60∘ with the plane of polarization? part e) what will be the intensity after passing through a polarizing filter whose axis makes the angle θ=90∘ with the plane of polarization?

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane

Ahanging spring stretches by 35.0 cm when an object of mass 450 g is hung on it at rest. in this situation, we define its position as x = 0. the object is pulled down an additional 18.0 cm and released from rest to oscillate without friction. what is its position x at a moment 84.4 s later? express your answer in cm.
