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. Having read the above passage, choose the right answer to the following question (choices are faster or slower ): Tina is speeding on the highway, and a cop is sat on the road with a radar gun to see who to pull over. The cop's gun begins to detect a low frequency, with waves reflected being bunched up. The car was going faster or slower?
slower

(Question)
Alkanes with more carbon atoms have higher boiling and melting points, so some of them are solids at room temperature. Having read the above passage, choose the right answer to the following question (choices are alkane with fewer carbon atoms or alkane with more carbon atoms? ): Kathy did some experiments on two different alkanes and one of the alkanes had twice as many carbon atoms than the other. She would notice that which alkane would require a higher temperature to melt alkane with fewer carbon atoms or alkane with more carbon atoms??
(Answer)
alkane with more carbon atoms?

Ques: Shorter wavelengths (higher frequencies) correspond to higher energies and thus hotter star temperatures. Having read the above passage, choose the right answer to the following question (choices are longer or shorter ): Don is sending out wavelengths, and wants them to correspond to lower energies. In order to best do this, Don will send out wavelengths that are longer or shorter?
Ans: longer

(Q).
When a person smokes there are chemicals released by the tobacco that enter the lungs. Because the lungs have to work harder to remove the chemicals, the body has to work harder to get the air needed to survive. Having read the above passage, choose the right answer to the following question (choices are increase or decrease ): If the amount of chemicals inside of Jim's lungs increases, what will happen to the amount of air his lungs can process increase or decrease?
(A).
decrease

Ques:The thinner the wire, the more resistance it offers. Having read the above passage, choose the right answer to the following question (choices are a bridge suspension cable or a paper clip ): Which wire likely has the lowest amount of resistance a bridge suspension cable or a paper clip?

Ans:a bridge suspension cable

Ques: Many observatories are built on high mountains. There is less air above the telescope, so there is less interference from the atmosphere. Having read the above passage, choose the right answer to the following question (choices are less or more ): Carter is at sea level and looks through a telescope. There is a lot of interference from the atmosphere, so Carter knows that above the telescope, there is less or more air than up on a mountain?
Ans:
more
