Answer 1

Answer:

Acceleration depends on slope and angle of incline

day and night are relative

Answer 2

Acceleration depends on both the slope of the incline and the angle of the incline; c) day and night are relative.

Explanation:

• Acceleration is the rate at which velocity changes with time, in terms of both speed and direction.
• A point or an object moving in a straight line is accelerated if its speed ups or slows down.
• As the angle increases, the force parallel to the incline also increases and the component of force perpendicular to the incline decreases.
• It is the parallel component of the weight vector which is responsible for the acceleration.
• So, accelerations are greater at greater angles of incline.
• Hence, the correct answer among all the options is option d) both a and b.
• Also, c) day and night are relative.
