Scaling Objects and Temperature Changes

If an object is scaled down to 1/4 of its original size in all dimensions (length, width, and height), how much of its original weight will it have, assuming it's made of the same material?

• 1/4 of its original weight

• 1/16 of its original weight

• 1/64 of its original weight

• 1/256 of its original weight

If you divide 352 by 4, and then divide the result by 4 again, what number do you get?

• 88

• 22

• 11

• 5.5

A 2-inch cube of aluminum weighs 352 grams. If a smaller cube of the same material is exactly 1/4 the size in each dimension, what would its weight be?

• 88 grams

• 22 grams

• 5.5 grams

• 1.375 grams

When scaling an object, why is the weight reduced by dividing by the scaling factor three times (or cubing the scaling factor in the denominator)?

• Because weight is measured in three units.

• Because there are three main types of materials.

• Because objects have three dimensions: length, width, and height.

• Because it's a common mathematical rule.

The water temperature in the hypothermia test was 29 degrees Fahrenheit. What is this temperature in degrees Celsius? (Use the formula: C = (F - 32) * 5/9)

• -1.67°C

• -0.56°C

• 1.67°C

• 2.78°C

What was the difference in temperature between the air and the water when the Titanic hit the iceberg?

• 2 degrees

• 4 degrees

• 6 degrees

• 8 degrees

If a person's temperature is checked every 30 seconds, how many times would their temperature be checked in 5 minutes?

• 5 times

• 10 times

• 15 times

• 20 times

A dummy started at 98.6°F. After 10 minutes in cold water, its temperature dropped to 94.6°F. How many degrees did its temperature drop in those 10 minutes?

• 2 degrees

• 8 degrees

At what body temperature does shivering stop?

• Below 96°F

• Below 91°F

• Below 85°F

• Below 82°F

After 49 minutes, a dummy in the air had a temperature of 85.3°F, while a dummy in the water had a temperature of 84.5°F. Which environment caused more heat loss from the dummy?

• Air

• Water

• Both caused the same amount of heat loss

• It cannot be determined from the given information
