Determine the momentum of a 650-kg motorcycle moving eastward at 35 m/s.

  • 22,750 kg m/s east

  • 18.6 kg m/s east

  • 22.8 kg m/s east

  • 2,275 kg m/s east

Correct answer: 22,750 kg m/s east

The motorcycle’s momentum is 22,750 kg m/s east. 

The formula for momentum is mass times velocity. Thus, 650 kg x 35 m/s = 22,750 kg m/s east.

164.

If Object A and Object B are both charged with like charges, which of the following statements is true?

  • Object A and Object B will repel each other

  • Object A and Object B will be attracted to each other

  • Object A has a negative charge and Object B has a positive charge

  • Object A’s force is directed leftward and Object B’s force is directed leftward

Correct answer: Object A and Object B will repel each other

When two objects are charged with like charges, they will repel one another. 

When two objects are charged with opposite charges, they will be attracted to one another. The question states that both objects are charged with like charges; therefore, they would both have a negative charge or they would both have a positive charge.

165.

Forty-five percent of the employees answered that they were not satisfied with the leadership of the organization. If that percentage equals 36 employees, how many employees answered the question?

  • 80 employees

  • 55 employees

  • 64 employees

  • 92 employees

Correct answer: 80 employees

In order to solve the question, convert 45% to a decimal.

45% = 45/100 = 0.45

Then use the following equation with n representing the number of employees that answered the question.

0.45n = 36

n = 36 ÷ 0.45

n = 80

166.

The diameter of a carbon atom is 0.000 000 000 154 m. How is this number expressed in scientific notation?

  • 1.54 x 10⁻¹⁰

  • 1.54 x 10¹²

  • 1.54 x 10⁻¹²

  • 1.54 x 10¹⁰

Correct answer: 1.54 x 10⁻¹⁰

Because the decimal place is moving to the right, the exponent would need to be negative. We see that the decimal has moved ten places, therefore the exponent -10 is correct. 

Positive exponents would move the decimal to the left, thereby increasing the number substantially.

Read the supporting details then correct the sentence below.

Sentence 5: The meters are sometimes met with resistance from citizen groups; vigilantes from Alabama and Texas attempted to destroy the meters en masse.

Which of the following changes should be made to correct sentence 5?

  • Change “are” to “were”

  • Insert a comma after Alabama

  • Change “resistance” to “resistances”

  • Change “to” to “two”

Correct answer: Change “are” to “were”

In order to correct sentence 5, you would need to change “are” to “were.” The sentence is written in the past tense; therefore, the verb needs to also be written in the past tense. “Are” is a present tense verb and “were” is a past tense verb. 

When there are only two items in a list, you should not use a comma after the first item. The other answer options are not options that would make the sentence grammatically correct.

168.

Kristina travels 25 miles to work. In the mornings, it takes her 38 minutes to get to work, but in the evenings, it only takes her 32 minutes to get home. What is Kristina’s average speed for the entire journey to work and back home?

  • 42.9 mph

  • 91.2 mph

  • 46.9 mph

  • 21.4 mph

Correct answer: 42.9 mph

Kristina’s average speed is 42.9 mph. The formula to find speed is distance over time. 

Average speed = [(25 miles * 2) ÷ (38 min + 32 min)] * (60 min / 1 hr) = 42.9 mph.

169.

Read the supporting details then correct the sentence below.

Sentence 1: In the United States most jobs are now located in the suburbs than in central cities as a result of the movement of commercial and industrial parks from the inside to the outside of the city.

Which of the following changes should be made to correct sentence 1?

  • Change “most” to “more”

  • Change “commercial” to “commercials”

  • Change “than” to “then”

  • Change “are” to “is”

Correct answer: Change “most” to “more”

In order to correct sentence 1, you should change “most” to “more.” The sentence is referring to jobs that are located in either a suburb or a city (two objects); therefore, you would want to use “more,” as “most” would be used to refer to three or more objects. 

You would use “than” in a comparative sentence (i.e., suburbs versus cities) and you would use “then” as a time marker or with a sequence of events; therefore, “than” is used correctly in this sentence. The other answer options are not options that would make the sentence grammatically correct.

170.

If Craig can walk 2 miles in 26 minutes, how long will it take him to walk 5 miles?

  • 1 hour 5 minutes

  • 52 minutes

  • 1 hour 26 minutes

  • 1 hour 35 minutes

Correct answer: 1 hour 5 minutes

Set up a proportion to find the answer.

2 miles / 26 minutes = 5 miles/ x minutes

2/26 = 5/x

Cross multiply to solve.

2x = 130

x = 65 minutes

There are 60 minutes in an hour, so 65 minutes is equivalent to 1 hour 5 minutes.

171.

Which of the following represents the correct electron configuration for beryllium (Be – 4)?

  • 1s² 2s²

  • 2s¹ 2s²

  • 2s² 1s¹

  • 1s¹ 1s¹ 2p¹

Correct answer: 1s² 2s²

Beryllium has an atomic number of 4, which means that it has 4 protons and, when balanced, it has 4 electrons. The superscripts of the electron configurations indicate the number of electrons that are in each subshell. Therefore, 1s² 2s² is the only option that has superscripts totaling 4.

172.

How did railroads contribute to changes in the American West?

  • It allowed the movement of people, goods, and raw materials

  • Native Americans could keep their land and culture

  • The land became too crowded

  • Most Americans didn't benefit from the railroad

Correct answer: It allowed the movement of people, goods, and raw materials

The Transcontinental Railroad made it possible for people and goods from the east to travel west. Raw materials could be shipped from the east or west and benefit businesses and factories.

The following is a price list for Matt's Pizzeria:

  • Small Pizza - $6.99
  • Medium Pizza - $7.99
  • Large Pizza - $9.99

What is the total cost if Alex orders two large pizzas, and a small pizza?

  • $26.97

  • $27.97

  • $13.98

  • $20.97

Correct answer: $26.97

Two large pizzas cost twice as much as one:

$9.99 * 2 = $19.98

A small pizza costs $6.99

The total cost is $19.98 + $6.99 = $26.97

Read the supporting details then answer the following question.

Which of the following options best describes the Arctic culture area?

  • A frozen desert

  • A sandy beach

  • A rainforest

  • A frozen forest

Correct answer: A frozen desert

The option that best describes the Arctic culture area is a frozen desert. The passage’s first sentence describes the Arctic’s culture area. 

You may have thought that the correct option was “a sandy beach” due to the Aleut living along the shoreline or the fact that the natives used seal and otter skins, but the passage did not imply that the Arctic culture had any sandy areas.

176.

Sheila borrows $18,000 to make improvements to her kitchen. If the simple interest rate is 9% and she has the loan for a period of seven years, how much will she pay in interest?

  • $11,340

  • $10,720

  • $8,920

  • $9,840

Correct answer: $11,340

The question asks for the total amount of interest, so multiply the amount of the loan by the interest rate by the number of years: $18,000 × 0.09 × 7 = $11,340.

Read the supporting details then correct the sentence below.

Sentence 6: Our volunteers say they feel rewarded many times over for the help they provide in making a difference in the live’s of others.

Which of the following changes should be made to correct sentence 6?

  • Change “live’s” to “lives”

  • Change “Our” to “Are”

  • Change “rewarded” to “rewards”

  • Change “provide” to “provided”

Correct answer: Change “live’s” to “lives”

In order to correct sentence 6, you will need to change “live’s” to “lives.” The word “live’s” is not showing possession of something; therefore, it should be changed to the plural noun “lives” to match the plural noun “others.” 

The other answer options are not options that would make the sentence grammatically correct.

178.

Tiffany is looking at a right triangle, where angle B is identified as being 42 degrees. How many degrees would angle C be, if angle A is the 90 degree angle?

  • 48

  • 228

  • 52

  • 42

Correct answer: 48

Every triangle contains 180 degrees. You will need to subtract the degrees of angles A and B to find the degrees of angle C: 180 - 90 - 42 = 48.

In 6 hours, Laura can bake 12 cakes. If she continues to work at that rate, how many cakes can she bake in 9 hours?

  • 18

  • 24

  • 27

  • 32

Correct answer: 18

Let x = the number of cakes Laura can bake in 9 hours, and then set up a proportion.

6 / 12 = 9 / x

6x = 12(9)

6x = 108

x = 18

Repulsive force is strongest when _______.

  • Two charged objects are close together

  • Two charged objects are spread apart

  • Two objects have the least amount of charge

  • One object is charged and the other object is not

Correct answer: Two charged objects are close together

Repulsive force is strongest when two charged objects are close together. 

The more charged an object is, the greater force it has. The less distance between two objects, the greater repulsive force it has.
