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 1

Answer:

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

A new food source from the crossing of wheat and rye is called

Answers

Triticate is a crop species resulting from a plant breeder's cross between wheat (Triticum) and rye (Secale). It is produced by doubling chromosomes of the sterile hybrid that results when crossing wheat and rye. This doubling produces what is called a polyloid.

SOS:

The answer is triticum!!!

Which method would allow you to study the behavior of a tiger in its native habitat in India?

Answers

They are solitary animals, especially males who do not live in groups, unlike the female which can form small groups of three or four members with their young.

The males are very territorial, so take care of their personal space and the females with whom they mate. To mark their territory, they spray the trees and rocks with a mixture of urine and musk.

Both male and female, they are related only in times of mating and reproduction. There have been cases where the male is responsible for feeding breeding if the mother has died.

The gestation period lasts between 98 and 108 days and give birth to two to four cubs weighing just over a kilo. They have a short life expectancy, as only get to live 10 to 12 years in the wild, but in captivity Natural mortality manage to live up to 26. It is mainly due to the fighting between males

Energy is released to be used by a cell when a phosphate group isremoved from ADP to form ATP
added to ADP to form ATP
removed from ATP to form ADP
added to ATP to form ADP

Answers

Answer:

Energy is released to be used by a cell when a phosphate group is removed from ATP to form ADP.

Explanation:

Hello,

Adenosine diphosphate (ADP) is an important organic compound with a chemical formula C₁₀H₁₅N₅O₁₀P₂. It helps in metabolic activities and facilitates energy flow in living cells. The adenine in ADP combines with sugar molecules to form adenosine that can accept a phosphate group, upto 3 of them.

ATP is adenosine 5' triphosphate. This molecule is primary energy carrier in living organisms as it stores and transfer energy to living cells.Those in living things, both ATP and ADP store and release energy, more energy is in ATP than ADP.

During hydrolysis, a phosphate group is removed through the breakdown of high-energy bonds called phosphoanhydride bonds and energy is given out as ATP coverts to ADP.

So, the correct answer is the third option.

Answer:

The correct answer is the c = removed from ATP to form ADP

Explanation:

Hello ! Let's solve this!

It is a catabolic process where energy is released and formed from a complex molecule, simpler molecules. In this case, to release energy, ATP (adenosine triphosphate) removes a phosphate group to form ADP (adenosine diphosphate).

The correct answer is the c = removed from ATP to form ADP
