Kennedy measured the daily high temperature outside her home for four days. She compared these measurements to the average high temperature for her region using the table below.

• The recent temperatures are lower than the normal average for her region.

• The recent temperatures are higher than the normal average for her region.

• The season is changing because there is a large difference between recent temperatures and average high temperatures.

• The season is changing because there is a small difference between recent temperatures and average high temperatures.

Answer explanation

Kennedy's recent temperature measurements were lower than the normal average for her region, indicating that the correct choice is that the recent temperatures are lower than the normal average.

A meteorologist reads a barometer at 9:00 a.m. He reads it again in the afternoon and notices a significant drop in pressure. Which choice describes the most likely weather in the evening for that location?

• It will be a sunny, clear evening.

• It will be a hot and humid evening.

• There will be many storms.

• There will be a light breeze.

Answer explanation

A significant drop in barometric pressure typically indicates an approaching storm system. Therefore, the most likely weather in the evening will be storms.

According to Figure 2, how far did the truck travel in 3 seconds while carrying two blocks?

• 12 inches

• 18 inches

• 24 inches

• 30 inches

Answer explanation

The truck traveled 8 inches per second while carrying two blocks. In 3 seconds, it covered 8 inches/second x 3 seconds = 24 inches, making 24 inches the correct answer.

At what time did the truck reach the 12-inch mark?

Answer explanation

The truck reached the 12-inch mark at 0:00, which is the starting point. Therefore, the correct answer is 0, indicating it reached the mark immediately.

Ziba pushed the truck in each investigation with equal force. Select (click) two choices that explain the difference in motion shown in Figure 1 and Figure 2.

• Putting blocks in the truck increased the truck’s total mass.

• Putting blocks in the truck decreased the truck’s total mass.

• Ziba’s push produced a greater change in motion when the truck carried no blocks.

• Ziba’s push produced the same change in motion when the truck was empty and when it carried two blocks.

• Ziba’s push produced a greater change in motion when the truck carried two blocks.

Answer explanation

Putting blocks in the truck increased its total mass, making it harder to move. Ziba's push had a greater effect on motion when the truck was empty, as less mass allows for greater acceleration.

Ziba determines the truck weighs 35 ounces when holding two blocks. She removes the blocks and weighs the truck again; the truck weighs 29 ounces. Which choice best explains the change in weight?

• A. Each block added 6 ounces of weight to the truck.

• B. Each block added 3 ounces of weight to the truck.

• C. Each block added to the weight of the truck by decreasing friction.

• D. Each block added to the weight of the truck by increasing friction.

Answer explanation

The truck weighs 35 ounces with two blocks and 29 ounces without them. The difference is 6 ounces, so each block must weigh 3 ounces (6 ounces ÷ 2 blocks = 3 ounces per block). Thus, B is correct.

Ziba then repeated the procedure, but this time placed two blocks into the back of the truck. Figure 2 shows the position and time measurements for the truck that carried two blocks. What was the speed of the truck from Figure 2?

• 2 inches per second

• 6 inches per second

• 8 inches per second

• 24 inches per second

Answer explanation

The speed of the truck is determined from Figure 2, which indicates it is moving at 6 inches per second. This is the only option that matches the data provided in the figure.

Which choice best describes the motion shown in Figure 1 and Figure 2?

• Figure 1 shows that the truck’s speed changed over time.

• Figure 2 shows that the truck’s speed changed over time.

• Figure 1 and Figure 2 show that each truck’s speed remained the same over time, but the truck from Figure 2 moved faster.

• Figure 1 and Figure 2 show that each truck’s speed remained the same over time, but the truck from Figure 1 moved faster.

Answer explanation

Figure 1 and Figure 2 indicate that both trucks maintained constant speeds. However, the truck in Figure 1 is moving faster than the one in Figure 2, confirming the correct choice.

How far will the truck in Figure 1 have travelled after moving for 4 seconds?

• 11 inches

• 36 inches

• 44 inches

• 55 inches

Answer explanation

The truck travels at a speed of 9 inches per second. After 4 seconds, it will have moved 9 inches/second * 4 seconds = 36 inches, making 36 inches the correct answer.

Which statement best explains how the Gulf Stream affects the climate of North Carolina?

• The Gulf Stream pulls warm water from the north, making temperatures warmer during the winter and bringing more precipitation to the state.

• The Gulf Stream brings warm water from the south, making temperatures warmer during the winter and bringing more precipitation to the state.

• The Gulf Stream pushes winds eastward across the United States, preventing precipitation within the state.

• The Gulf Stream pushes wind westward across the ocean, making temperatures much cooler within the state.

Answer explanation

The correct statement explains that the Gulf Stream brings warm water from the south, which raises winter temperatures and increases precipitation in North Carolina, influencing its climate positively.
