Determine the amount of potential energy of a 5.0Kg book that is moved to three shelves on a bookcase. The height of each shelf is 1.0 meters, 1.5 meters, and 2.0 meters.

Answers

Answer:

The potential energy is 50 joules, 75 joules and 100 joules

Explanation:

Potential energy is the energy stored in an object by virtue of its position relative to others objects. For example a heavy ball placed at an elevated position.

The potential energy is given as:

$E_(p)=mgh$

Where $E_(p)$ is the potential energy of the object, m is the mass of the object, h is the height in which the object is placed and g is the acceleration due to gravity.

For 1.0 meters:

m = 5.0 kg g = 10 m/s² h = 1 meters

$E_(p)=mgh= 5.0*10*1=50$

The potential energy is 50 joules

For 1.5 meters:

m = 5.0 kg g = 10 m/s² h = 1.5 meters

$E_(p)=mgh= 5.0*10*1.5=75$

The potential energy is 75 joules

For 2.0 meters:

m = 5.0 kg g = 10 m/s² h = 2 meters

$E_(p)=mgh= 5.0*10*2=100$

The potential energy is 100 joules

Introducing invasive species to an ecosystem results in an increase in biodiversity.true or false ?

Answers

Correct answer: False

Invasive species are those species, which lower the biodiversity to a such an extent that they can create monotypic community.

Invasive species can be any type of living organism like plant, insect, fungus, fish, bacteria or seeds of the organism or eggs that are not native to an ecosystem and can cause a great harm to the ecosystem, economy, health, and the environment too.

This is usually false since invasive species usually cause the extinction of other native species which actually means that biodiversity becomes smaller.

A factor that is necessary for the formation of a new species is
