Use information from the paragraph to answer the question. Paragraph : This means that as wavelengths get shorter, more waves move past a particular spot in the same amount of time. Question: What happens to the rate at which waves move past a particular spot if Jim decreases the wavelength of a sound wave increases or decreases?
increases

Use information from the paragraph to answer the question. Paragraph : A: As the car approaches the radar gun, the reflected microwaves get bunched up in front of the car. Therefore, the waves the receiver detects have a higher frequency than they would if they were being reflected from a stationary object. The faster the car is moving, the greater the increase in the frequency of the waves. Question: If Mona is bouncing radar waves off a test car when training to be a policewoman and she notices the frequency of the waves returning to her radar gun is higher then it was before, what is happening to the car she is pointing the gun at decreasing in speed or increasing in speed?
increasing in speed

Use information from the paragraph to answer the question. Paragraph : Inhaling, or breathing in, increases the size of the chest, which decreases air pressure inside the lungs. Question: If Mona is running a race and her chest expands, what happens to the amount of air pressure in her lungs increases or decreases?
decreases

Use information from the paragraph to answer the question. Paragraph : Wave frequency can be measured by counting the number of crests or compressions that pass the point in 1 second or other time period. The higher the number is, the greater is the frequency of the wave. Question: As waves get larger the frequency of them increases or decreases?
decreases
