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.
Ingredients in Kool-Aid solution include water, flavoring, and sugar. How do the physical properties of the sugar change when the solution's ingredients are combined?
The sugar particles maintain their physical state, size, and mass as they mix evenly with the water and flavoring
The sugar particles change in mass as they mix evenly with the water and flavoring
The sugar particles change to water particles as they mix evenly with the water and flavoring
The sugar particles change in size as they mix evenly with the water and flavoring

A student made a mixture using equal amounts of sugar and small grains of rice. The sugar grains were the same size as the pepper. What should the student do to most easily separate the pepper from the salt?
Use a strainer with a fine wire screen to remove the pepper
Put the mixture in water and filter the pepper out of the water
run a small magnet through the mixture to attract the pepper
use a pair of tweezers to remove each grain of pepper
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 air and then into water are reflected
the rays of light that travel through air and then into water are reduced
