Measure the mass of the Aluminum "unknown" using the torque apparatus, and the volume using the vernier caliper. Then determine its density and quantitatively compare that density to the Aluminum density value listed in Appendix II of the lab manual (show all work). Your result should be a little bit high; what would be the primary cause of such an error? Explain

True or false graphs must include scales that increase by the same amount

Asled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slidesa distance d1 down the slope and then covers the distance d2 alongthe horizontal terrain before stopping. find the coefficient ofkinetic friction μk between the sled and the ground, assumingthat it is constant throughout the trip. find the coefficient of kinetic frictionμk. express your answer in terms of someor all of the variables d1, d2, and θ.
