Use the drop down menus to complete each sentence the force applied to the physics cart is manipulated. this is the blank variable. the cart accelerated due to the force applied to the cart. acceleration is therefore blank variables the concert is a parameter that stays the same regardless of the variables. one parameter of a car that is held constant is the blank.

Aperson stands on a platform, initially at rest, that can rotate freely without friction. the moment of inertia of the person plus the platform is ip. the person holds a spinning bicycle wheel with its axis horizontal. the wheel has moment of inertia iw and angular velocity ωw. take the ωw direction counterclockwise when viewed from above. part a what will be the angular velocity ωp of the platform if the person moves the axis of the wheel so that it points vertically upward?

Aperson walks first at a constant speed of 4.89 m/s along a straight line from point a to point b and then back along the line from b to a at a constant speed of 2.95 m/s. what is the average speed over the entire trip?

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.
