What are some ways to increase gravitational potential energy?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.

Are apples renewable or nonrenewable?
Let’s take a look at Apple’s flagship data center in Maiden, NC. Apple claims that it is 100% renewable, running predominantly on its own solar capacity and fuel cells.
Is the fruit Apple renewable or nonrenewable?
The fact that more apples can be grown, even after previous apples are consumed, makes the delectable fruit a renewable resource.
Do apple trees produce oxygen?
In the process of living and growing, apple trees take up carbon dioxide and release oxygen during photosynthesis, and in the process, they release moisture and evaporatively cool the air. The trees and grass take up about 20 tons of carbon dioxide and release 15 tons of oxygen.
Is a cow renewable or nonrenewable?
They are renewable natural resources. They move round and round in cycles and never run out. When an animal like this cow eats a plant, it takes in nutrients. The nutrients are used in the animal’s body and then many come out as waste, which returns the nutrients to the soil.
How much CO2 does an apple tree absorb?
A typical tree can absorb around 21 kilograms of carbon dioxide (CO2) per year, however this figure is only achieved when the tree is fully grown – saplings will absorb significantly less than this. Over a lifetime of 100 years, one tree could absorb around a tonne of CO2.
How many trees does it take to offset a ton of CO2?
6 trees
Which trees absorb the most carbon dioxide?
While oak is the genus with the most carbon-absorbing species, there are other notable deciduous trees that sequester carbon as well. The common horse-chestnut (Aesculus spp.), with its white spike of flowers and spiny fruits, is a good carbon absorber. The black walnut (Juglans spp.)
