Question 1

What is the process by which water vapor cools and changes into liquid water called?

Accepted Answer

Condensation

Answer

Condensation occurs when water vapor loses heat energy and changes into liquid water droplets.

Question 2

If an unbalanced force acts on an object, then the object will begin to accelerate according to:

Accepted Answer

Newton's Second Law

Answer

Newton's Second Law of Motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma). This means that if an unbalanced force acts on an object, it will cause the object to change its velocity, i.e., accelerate. Newton's First Law describes inertia, and Kepler's Laws relate to planetary motion.

Question 3

What is the speed of light in a vacuum, approximately?

Accepted Answer

300,000 km/s

Answer

Light travels at approximately 300,000 kilometers per second (3 × 10⁸ m/s) in a vacuum.

Question 4

If a bowling ball is pushed with 20 Newtons of force and has a mass of 4 kg, what is its initial acceleration?

Accepted Answer

5 m\/s^2

Answer

Newton's Second Law of Motion states that Force (F) equals Mass (m) times Acceleration (a), or F = ma. To find the acceleration, rearrange the formula to a = F/m. Given a force of 20 Newtons and a mass of 4 kg, the acceleration is 20 N / 4 kg = 5 m/s².

Question 5

Which planet in our solar system has the most moons?

Accepted Answer

Saturn

Answer

Saturn has the most confirmed moons of any planet in our solar system, surpassing Jupiter in recent counts.
