Question 1

What color should your automobile not be painted if you don't want it to quickly overheat on a sunny day?

Accepted Answer

Matte black

Answer

Darker colors, especially matte finishes, absorb significantly more solar radiation than lighter or reflective colors. Matte black absorbs the most heat, causing the car's interior and exterior to heat up more quickly and to a higher temperature on a sunny day.

Question 2

How many rotations a second does C make?

Accepted Answer

10

Answer

This question refers to a diagram of interconnected gears. To determine the rotations per second of gear C, one would typically use the gear ratio principle: the product of the number of teeth and rotations per second is constant for meshing gears. By comparing the number of teeth on gear C to a driving gear with a known rotation speed, the rotations per second for C can be calculated based on the specific gear configuration shown in the diagram.

Question 3

Which viewpoint has the most potential for error?

Accepted Answer

C

Answer

This question refers to a diagram, likely illustrating different viewing angles for a measurement. Viewpoint C, often depicted as an oblique or angled perspective, is most prone to parallax error. Parallax occurs when the apparent position of an object changes due to a change in the observer's position, leading to inaccurate readings compared to a direct, perpendicular view.

Question 4

Which line on the graph most accurately depicts the acceleration of a car leaving a stop sign?

Accepted Answer

C

Answer

This question refers to a speed-time graph. A car accelerating from a stop sign starts with zero speed and continuously increases its speed. Line C typically represents a curve that starts at the origin (zero speed, zero time) and shows a progressively increasing slope, indicating positive and possibly increasing acceleration, which accurately depicts a car leaving a stop sign.

Question 5

Which container is depicted in this graph with water inside it?

Accepted Answer

B

Answer

This question refers to a graph showing the relationship between water volume and height for different container shapes. Container B would likely have a specific, non-uniform shape (e.g., wider at the bottom, narrower at the top, or vice versa) that results in a unique, non-linear curve on the graph as it fills with water. The graph for B would visually represent this specific volume-to-height characteristic.
