문제 #1

The figure below illustrates a workman pushing a box up an inclined plane (ramp). The ramp gives the workman a mechanical advantage (MA) and requires less effort. This setup provides an MA, which represents the length of the ramp's slope (4 meters) divided by its height (1 meter).
Exhibit:

How would you increase the MA of the ramp for this worker?

A. Increase the height of the box.
B. Pull the box.
C. Increase the length of the cart.
D. Increase the height of the ramp.
E. Increase the length of the ramp.

문제 #2

Almost all food containers and packages have nutrition labels such as the one below, which might appear on the container of a soft drink. These labels indicate the number of servings in the container and the ingredients of its contents. They will usually list the amount of fat, sodium, sugars, carbohydrates, and protein that are in the contents. People who are diabetic can not consume a large amount of sugar in their diet.
Which statement best describes the expected and MOST sensible reaction of a person who is diabetic when he or she reads the label on this container of soft drink?
Exhibit:

A. it contains no fat
B. it has a high glucose (sugar) content
C. it has 8 oz per serving
D. it contains more protein than you should consume in a day
E. it contains no calories

-- Exhibit -
Radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X rays, and gamma rays are forms of radiant energy that make up the electromagnetic spectrum. Each portion of the electromagnetic spectrum has waves that vary in frequency and wavelength, but all can be used by people. Radio waves can be used to carry music and voices for great distances through air, X rays can be used for diagnostic work in medicine, and infrared radiation can be used for heating and drying.

-- Exhibit -
Most genetic damage is caused by very short wavelengths of the electromagnetic spectrum.
Which of the following statements would support this statement?

A. Short wavelengths may be photographed.
B. Infrared light is used in night photography.
C. Gamma rays penetrate very deeply and are highly energetic.
D. Ultraviolet rays are stopped by the skin.
E. Microwaves may be used to carry telephone conversations.

-- Exhibit -
What appears to be the difference in the waves when moving from radio waves to X rays in the electromagnetic spectrum?

A. increased wavelength and energy
B. decreased frequency
C. decreased energy
D. increased wavelength and frequency
E. decreased wavelength

문제 #5

Uma wanted to test her hypothesis that fescue grass grows best under red light. Independent variables, such as size of fescue grass plants, soil type, number of plants, and length of exposure to light were kept identical for both the experimental and control groups. Uma exposed the experimental group to red, green, and blue light and the control group only to sunlight. She took daily measurements of plant height for the next three weeks.
During the second week, Uma noticed that 8 of the 10 plants that she had exposed to red light looked a little wilted. She increased the daily water amount for these 8 plants. At the end of the experiment, she concluded that fescue grass grows best under red light.
What is a possible flaw in Uma's experiment?

A. monitor the plants in the control group
B. give equal amounts of water to all plants
C. plant an equal number of plants under each treatment
D. keep track of plant growth under each treatment
E. plant all samples in the same type of soil
