The above free body diagram represents the motion of a toy car across a floor from left to right. the weight of the .5 kg car is about 5 n and it is being pushed with 20 n of pressure. if there is 10 n of friction across the floor, what is the net force acting on the car?

a

since the car is moving to the right, the normal force is balancing the weight and the net force is 10 n, right.

b

friction and the normal force are acting opposite the applied force, so the net force is 5 n, right.

c

the net force is 35 n, the addition of each of the forces acting on the car and causing it to accelerate.

d

net force is equal to mass times acceleration so the net force is .5 kg times 9.8 m/s^2 or roughly 5 n.

Since the investigative question has two variables, you need to focus on each one separately. thinking only about the first part of the question, mass, what might be a hypothesis that would illustrate the relationship between mass and kinetic energy? use the format of "if…then…because…” when writing your hypothesis.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
