The variables for Part II of this experiment include the force applied to the car and the acceleration of the car. Use the drop-down menus to complete the sentences and identify the independent and dependent variables.

The independent variable, the one that is intentionally manipulated, is .

The dependent variable, the one that you measure the response in, is .

Next a skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 15 with the horizontal. the rope moves parallel to the slope with a constant speed of 0.69 m/s. the force of the rope does 800 3 of work on the skier as the skier moves a distance of 8.4 m up the incline. (a) if the rope moved with a constant speed of 2.2 m/s how much work would the force of the rope do on the skier as the skler moved a distance of 8.4 m up the incline? at what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.69 m/s and (c) 2.2 m/s?

The speed of light in a material is 0.50 c. what is the critical angle of a light ray at the interface between the material and a vacuum?

When you push downward on a book at rest on a table, you feel an upward force. does this force depend on friction? defend your answer.
