A group of students wants to measure the effect of mass on the free fall of objects from a constant height. They choose four basketballs filled with different materials. The mass of the basketballs varied from 1 kg to 8 kg. The students decided to drop the basketballs from the top of the gym bleachers (10 m). Which BEST describes the speed of the fall of basketballs when dropped from a constant height, assuming no air resistance?

The speed at which each basketball falls is independent of the mass of the ball; thus, all the balls will fall at the same rate.

The 1 kg basketball will fall 8 times faster than the 8 kg basketball.

The 8 kg basketball will fall twice as fast as the 4 kg basketball but not 8 times faster than the 1 kg basketball.

The speed at which each basketball falls is directly related to the mass of the ball, thus as the mass increases the speed will also increase.

A student constructed a glass jar to study the distribution of electric charge. The inside of a wide-mouthed glass jar was smoothly and tightly lined with a layer of aluminum foil to about an inch from the top. The outside of the jar was coated with aluminum foil in the same way. A wooden top was placed on the jar. A nail with a trail of paper clips attached to it was inserted through the wooden top. The student safely charged the glass jar by touching a charged pie pan to the nail. Which of the following is the BEST explanation for the fully charged glass jar remaining fully charged and behaving like a jar of “stored electricity”?

The glass jar remains charged because the glass serves as an insulator to prevent the movement of the negatively charged particles towards the positively charged particles.

The glass jar remains charged because the glass serves as an insulator to prevent the movement of the positively charged particles towards the negatively charged particles.

The glass jar remains charged because the glass serves as an insulator to prevent the movement of negatively charged particles away from positively charged particles.

The glass jar remains charged because the movement of ions is completely unrestricted, allowing free flow of charges.

gravitational force would increase

gravitational force would remain constant

gravitational force would not be created

gravitational force would decrease

This diagram shows the different types of electromagnetic waves with their range of frequencies. Which explanation correctly compares the energy difference between X-rays and microwaves?

X-rays have more energy than microwaves because the energy of electromagnetic waves increases when their frequency is greater, and X-rays have a greater frequency than microwaves.

Microwaves have more energy than X-rays because the energy of electromagnetic waves increases when their frequency is lower, and microwaves have less frequency than X-rays.

X-rays have more energy than microwaves because the energy of electromagnetic waves increases when their wavelength is longer, and X-rays have a longer wavelength than microwaves.

Microwaves have more energy than X-rays because the energy of electromagnetic waves increases when their wavelength is longer, and microwaves have a longer wavelength than X-rays.

Kevin wants to understand how the velocity of a sound wave changes in different medium. Which of the following conclusions BEST describes the data Kevin collected?

Sound travels faster in the denser medium.

Sound travels slower in the denser medium.

Velocity of the sound wave does not change in the different media.

Velocity of the sound wave does not change in the different media but in the frequency.

How is mass of an object different from the weight of an object?

mass is the amount of matter, while weight is gravitational force

mass changes with gravity, while weight stays same with gravity

mass stays the same with gravity, while weight changes with gravity

Why must x-ray technicians take special precautions that radio technicians do not have to take?

D. X-rays have much shorter wavelengths than radio waves, allowing them to transport more energy.

A. X-rays have much shorter wavelengths than radio waves, and are able to travel over and around more objects.

B. X-rays have the same wavelengths as radio waves, but they are able to transport more energy.

C. X-rays have much longer wavelengths than radio waves, allowing them to transport more energy.

Look at the picture of the two waves. Which of the following statements BEST describes the changes between wave A and wave B and why?

A. The amplitude has increased and that caused the energy to increase.

B. The amplitude has increased and that caused the energy to decrease.

C. The amplitude has decreased and that caused the energy to increase.

D. The amplitude has decreased and that caused the energy to decrease.

Food can be cooked in half the time if it is cooked in a microwave. Which type of wave would need to be used in the microwave to cook food in half the time?

C. low Frequency, electromagnetic waves

A. low Frequency, mechanical waves

B. high Frequency, mechanical waves

D. high Frequency, electromagnetic waves

A speaker produces sound waves in a column of air. The sound waves move from left to right through the air column as shown in the diagram. Using information from the diagram, what is happening to the gas particles as the sound waves move? Explain.

The sound wave produces compressions in the air where the air particles are close together because the air pressure is lower in these regions.

The sound wave pushes the air particles along the column of air as it moves from left to right because the sound wave takes up space.

The sound wave produces compressions and rarefactions in the column of air. In compressions, the air particles are close together. The compressed air particles move with the sound wave.
