Ответ:
A) Independent
B) Dependent
C) Mass
Explanation:
The speed applied to the physics cart is manipulated. This doesn't depend on another variable. Thus, speed is the (independent) variable.
The cart accelerates due to the speed applied to the cart. Acceleration depends on the speed applied. Thus, acceleration is therefore the (dependent) variable.
A “constant” is a parameter that remains the same regardless of the variables.
One parameter of the cart that is held constant is the (mass).
