To assess whether your calculations are reasonable, we'll analyze a similar situation to the one described in the problem introduction. Suppose the same sled is released from the same height on the same slope. This time, however, assume that the coefficient of kinetic friction between the ground and the sled is a known quantity, μ, and, as before, constant throughout the trip. After the sled is released, it slides the same distance d1 down the slope and then moves a certain (unknown) distance along the horizontal terrain before stopping. Find the distance d traveled by the sled from the end of the slope until it comes to a stop.

Which lists the main components of darwin’s theory of evolution? a. random mutations drive evolution; the evolution of a population happens slowly; organisms have common ancestors; organisms do not change. b. natural selection drives evolution; the evolution of a population happens slowly; organisms have common ancestors; organisms change over time. c. natural selection drives evolution; the evolution of a population happens rapidly; organisms have common ancestors; organisms change over time. d. random mutations drive evolution; the evolution of a population happens rapidly; organisms have common ancestors; organisms do not change.

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b
