Answer 1

Marble D

Step-by-step explanation:

According to this question, a group of four students is participating in a marble race. Each marble is said to have different mass but the same force were applied to each of them.

The relationship between the mass, force and acceleration of an object has been explained with the equation: F (force) = mass (m) × acceleration (a).

F = ma

Hence, a = F/m

Based on this, with a constant force, the acceleration is inversely proportional to the mass of an object. This means that when the mass increases, the acceleration decreases and vice versa. Based on the table showing the value for mass and uniform force for each marble, the marble with the highest mass (90) will have the least acceleration (0.66666). This marble is MARBLE D.
