A student designs an experiment to test the effect of forces on an object. The student compares pulling a block up a ramp with friction to pulling it up a ramp with less friction. What does the student conclude about the force required to pull the blocks up the ramps?

• The amount of force required to pull the blocks up is the same for both ramps.

• The ramp with less friction required less force to pull the block up the ramp.

• The ramp with less friction required more force to pull the block up with ramp.

• The ramp with more friction required less force to pull the block up the ramp.

What is happening to the straw and why does the lower part appear slightly different in size from the upper part?

• The rays of light that travel through water and then into air are refracted

• the rays of light that travel through water and then into air are englarged

• the rays of light that travel through air and then into water are reflected

• the rays of light that travel through air and then into water are reduced
