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) .

Can anybody me with this? ? (picture included.)

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value
