A block slides down a frictionless inclined ramp. If the ramp angle is 17. 0° and its length is 30. 0m find the speed of the block as it reaches the bottom of the ramp, assuming it started sliding from rest at the top.

Layer r contains a well-known index fossil that is 100 million years old. based on this information and the principle of superposition, a. layers t and m are older than 100 million years, and layers x and g are younger than 100 million years. b. layers t, m, x, and g are all older than 100 million years. c. layers t and m are younger than 100 million years, and layers x and g are older than 100 million years.
