Andrew and Maria each collected six rocks, and the masses of the rocks are shown in the table above. The mean of the masses of the rocks Maria collected is 0.1 kilogram greater than the mean of the masses of the rocks Andrew collected. What is the value of x ?

What are the effects of propagation of earthquake waves on the rock mass through which they travel?

A rock of higher mass resting on a cliff has more energy than the one which has less mass at the same height.

Five samples of each of three different rock types were collected on a hiking trip in Colorado. Each sample was analyzed for its gold content. The milligrams of gold found in each sample are presented in the table above. How much larger is the median of the amount of gold in the granite samples than that of the limestone samples?

Five samples of each of three different rock types were collected on a hiking trip in Colorado. Each sample was analyzed for its gold content. The milligrams of gold found in each sample are presented in the table above. What is the percent difference of the average gold content in the granite samples when compared to the average gold content of the gneiss samples?

A rock of mass m is dropped to the ground from a height h . A second rock, with mass 2m , is dropped from the same height. When the second rock strikes the ground, what is its kinetic energy? (a) Twice that of the first rock, (b) four times that of the first rock, (c) same as that of the first rock, (d) half as much as that of the first rock, (e) impossible to determine.

The weight of a rock on the moon is 200.6 N. What is its mass on the earth?

A man drops a 10 kg rock from the top of a 20 m ladder. What will be its kinetic energy when it reaches the ground ? What will be its speed just before it hits the ground ? Does the speed depend on the mass of the rock ?

Select the word which means the same as the group of words given. A mass of snow, ice, and rocks falling rapidly down a mountainside
