Question 1

What statement regarding levers is TRUE?

Accepted Answer

A lever is a kind of simple machine

Answer

Levers are fundamental mechanical devices that are classified as one of the six simple machines, alongside inclined planes, wedges, screws, pulleys, and wheels and axles. They are used to gain mechanical advantage, change the direction of force, or increase the range of motion. The other statements are incorrect; for example, a crowbar is typically a first-class lever, and levers have varying mechanical advantages.

Question 2

Even if an electric iron heats up, the cable that sends the current to it remains cool because of the?

Accepted Answer

Electric iron converts electricity into heat

Answer

An electric iron is specifically designed with a high-resistance heating element to efficiently convert electrical energy into thermal energy, which is its primary function. Conversely, the power cable is designed with very low resistance to minimize energy loss as heat during transmission. This difference in resistance explains why the iron gets hot while the cable remains relatively cool.

Question 3

What quantity maintains constant through a ballistic trajectory?

Accepted Answer

Acceleration

Answer

In a ballistic trajectory, assuming air resistance is negligible, the only force acting on the projectile is gravity. Gravity causes a constant downward acceleration of approximately 9.8 m/s² near the Earth's surface. Therefore, the acceleration remains constant in both magnitude and direction throughout the entire flight path of the projectile.

Question 4

Which one of the following DOES NOT function through magnetism?

Accepted Answer

Vehicle

Answer

A typical vehicle, especially one powered by an internal combustion engine, primarily functions through mechanical forces generated by burning fuel, not magnetism. In contrast, a compass relies entirely on the Earth's magnetic field for orientation, and an NMR (Nuclear Magnetic Resonance) apparatus uses powerful magnetic fields to analyze materials.

Question 5

Which of the materials listed below may function as a magnet?

Accepted Answer

None of the above

Answer

Zinc, copper, and aluminum are all non-ferromagnetic materials, meaning they are not strongly attracted to magnets and cannot be easily magnetized themselves. Only ferromagnetic materials, such as iron, nickel, cobalt, and their alloys, possess the properties necessary to function as magnets or be strongly attracted to them.
