Step-by-Step Answer Key

Step-by-Step Answer Key

1. Solve: x + 7 = 19

Subtract 7 from both sides:
x + 7 − 7 = 19 − 7
x = 12

Answer: x = 12

2. Solve: 4x = 28

Divide both sides by 4:
4x ÷ 4 = 28 ÷ 4
x = 7

Answer: x = 7

3. Solve: 3x − 5 = 16

Add 5 to both sides:
3x = 21
Divide by 3:
x = 7

Answer: x = 7

4. Solve: 2(x + 4) = 18

Distribute:
2x + 8 = 18
Subtract 8:
2x = 10
Divide by 2:
x = 5

Answer: x = 5

5. Solve: 5(x − 2) + 3 = 18

Distribute:
5x − 10 + 3 = 18
Combine like terms:
5x − 7 = 18
Add 7:
5x = 25
Divide by 5:
x = 5

Answer: x = 5

6. Solve: 3x + 8 = x + 18

Subtract x from both sides:
2x + 8 = 18
Subtract 8:
2x = 10
Divide by 2:
x = 5

Answer: x = 5

7. Solve: 4x + 2 = 4x − 6

Subtract 4x from both sides:
2 = −6
This statement is false.

Answer: No solution

8. Solve: 2(x + 3) = 2x + 6

Distribute:
2x + 6 = 2x + 6
Subtract 2x from both sides:
6 = 6
This statement is always true.

Answer: Infinitely many solutions (all real numbers)

1. Which of Newton's Laws says that an object at rest stays at rest unless acted on by an unbalanced force?
- Newton's First Law
- Newton's Second Law
- Newton's Third Law
- Law of Gravity
Correct answer: Newton's First Law
Explanation: Newton's First Law is the law of inertia.

2. What is velocity?
- Speed only
- Distance traveled
- Speed with direction
- A force
Correct answer: Speed with direction
Explanation: Velocity includes both speed and direction.

3. A rocket pushes gas downward and moves upward. Which law explains this?
- First Law
- Second Law
- Third Law
- Law of Conservation
Correct answer: Third Law
Explanation: For every action, there is an equal and opposite reaction.

4. What is acceleration?
- A change in velocity over time
- Distance divided by time
- A type of force
- Speed only
Correct answer: A change in velocity over time
Explanation: Acceleration is any change in velocity, including speeding up, slowing down, or changing direction.

5. If the forces on an object are balanced, what is the net force?
- 10 N
- 1 N
- 0 N
- 100 N
Correct answer: 0 N
Explanation: Balanced forces cancel, giving a net force of 0 N.

6. A car travels 120 m in 6 s. What is its speed?
- 20 m/s
- 720 m/s
- 114 m/s
- 14 m/s
Correct answer: 20 m/s
Explanation: Speed = distance ÷ time = 120 m ÷ 6 s = 20 m/s.

7. A force of 15 N acts right and a force of 5 N acts left. What is the net force?
- 20 N right
- 10 N right
- 10 N left
- 75 N
Correct answer: 10 N right
Explanation: 15 N - 5 N = 10 N to the right.

8. A bicycle's velocity changes from 2 m/s to 10 m/s in 4 s. What is its acceleration?
- 2 m/s²
- 4 m/s²
- 8 m/s²
- 40 m/s²
Correct answer: 2 m/s²
Explanation: Acceleration = (10 - 2) ÷ 4 = 2 m/s².

9. According to Newton's Second Law, increasing force while mass stays the same will:
- Decrease acceleration
- Increase acceleration
- Keep acceleration unchanged
- Stop motion
Correct answer: Increase acceleration
Explanation: F = ma, so more force causes more acceleration when mass is constant.

10. Which situation best demonstrates inertia?
- A soccer ball starts rolling after being kicked
- Passengers lurch forward when a car stops suddenly
- A rocket launches
- A magnet attracts a paperclip
Correct answer: Passengers lurch forward when a car stops suddenly
Explanation: Passengers continue moving forward because their bodies resist changes in motion.

Answer Key with Worked Solutions

1. Newton's First Law
Answer: A
Objects remain at rest or in motion unless acted on by an unbalanced force.

2. Speed with direction
Answer: C
Velocity is speed in a specific direction.

3. Newton's Third Law
Answer: C
The rocket pushes gas downward, and the gas pushes the rocket upward with an equal and opposite force.

4. A change in velocity over time
Answer: A
Acceleration measures how quickly velocity changes.

5. 0 N
Answer: C
Balanced forces cancel each other out, so the net force is zero.

6. Speed Calculation

Question: A car travels 120 m in 6 s. What is its speed?

Formula:
Speed = Distance ÷ Time

Work:
Speed = 120 m ÷ 6 s
Speed = 20 m/s

Answer: A. 20 m/s

7. Net Force Calculation

Question: A force of 15 N acts right and a force of 5 N acts left. What is the net force?

Formula:
Net Force = Larger Force − Smaller Force

Work:
15 N − 5 N = 10 N

Direction is toward the larger force (right).

Answer: B. 10 N right

8. Acceleration Calculation

Question: A bicycle's velocity changes from 2 m/s to 10 m/s in 4 s. What is its acceleration?

Formula:
Acceleration = (Final Velocity − Initial Velocity) ÷ Time

Work:
Acceleration = (10 m/s − 2 m/s) ÷ 4 s
Acceleration = 8 m/s ÷ 4 s
Acceleration = 2 m/s²

Answer: A. 2 m/s²

9. Increase acceleration
Answer: B
According to Newton's Second Law (F = ma), increasing force increases acceleration when mass stays the same.

10. Passengers lurch forward when a car stops suddenly
Answer: B
This demonstrates inertia, the tendency of objects to resist changes in motion.

How Honeybees Communicate

Honeybees live in large colonies that depend on teamwork to survive. Because thousands of bees may share one hive, they need ways to communicate important information to one another. Honeybees use movement, scent, and touch to send messages that help the colony find food and stay organized.

One of the most famous forms of honeybee communication is the “waggle dance.” When a worker bee finds a good source of nectar or pollen, it returns to the hive and performs this special dance. During the dance, the bee moves in a figure-eight pattern while waggling its body. The direction of the dance shows other bees where the food is located in relation to the sun. The length of the waggle can also provide information about how far away the food source is.

Honeybees also communicate through chemicals called pheromones. These chemical signals can alert other bees to danger, help workers recognize members of their colony, or guide the activities of the hive. For example, when a bee stings a predator, it releases a pheromone that can attract other bees to defend the colony.

Touch is another important communication tool. Inside the dark hive, bees often use their antennae to touch one another. This contact helps them share information and coordinate tasks. By combining dance, scent, and touch, honeybees can work together efficiently. Their communication system is so effective that it allows thousands of individual insects to function as a single, organized community.
