A scientist wants to figure out the coefficient of friction between a wooden box and a brick walkway outside of his house. He determines that the box weighs 20 kg and that the force of friction when he slides it is 163 N. What is the coefficient of friction between the box and the walkway?

To run the physics cart, the fan speed of the cart is manipulated. this is the (blank) variable. the cart accelerates due to the speed of the fan. acceleration is therefore the (blank) variable. a “constant” is a parameter that stays the same regardless of the variables. one parameter of the cart that is held constant is the (blank) .
