How does the mass of a bowling ball that has been rolled down the lane affect the kinetic energy?
Simora [160]

Answer is: B) The kinetic energy is increasing proportional to the mass of the bowling ball.

Kinetic energy has to do with the speed of an object and how much mass it has; basically how the object is moving.

Ek = 1/2 · m(bowling ball) · v²(bowling ball).

m is mass; v is speed of bowling ball.

The standard unit of kinetic energy is the joule.

Answer:

Change in plate tectonic leads to change in earth surfaces.

Plate tectonics have changed Earth’s surface over time because the earth surface is placed on these plate tectonics. Earth's outer surface is divided into various plates that slowly move over the mantle which changes Earth's surface over time by merging and separating of landmasses that turn into continents.

The movement of tectonic plates is responsible for the creation of landforms such as volcanoes and ridges. Some volcanoes are formed when the tectonic plates pull apart from one another whereas some volcanoes are produced when a tectonic plate slides over one another so we can conclude that change in plate tectonic leads to change in earth land forms.
