If we know the total energy in a system is 30 j, and we know the PE is 20 j, what is the KE?

Answers

Answer 1

Answer: 30j-20j= 10j

The kinetic energy is 10 joules

The total energy is equivalent to PE+KE. Therefore the answer is 10 joules.

Explain how scientific advancements have lessened the effects of hazardous events on society.

Answers

Answer:

Scientific advancements can detect some harmful events before they occur and it allows the society to plan for them, thereby reducing the risk of damage that occurs.

Explanation:

Scientific advancements reduce the natural disasters level in a region by evaluating the physical and chemical characteristics of the land.

Also, it develops new medical terminology and concepts that reduce the spread of hazardous diseases in society.

Satellites are used to predict the weather report and by using this report proper precautions can be taken at the time of floods and storms.

Construction of dams and canals highly reduced the risk of water overflowing in the lands.

Answer: Scientists are able to detect and predict some hazardous events through scientific advancements. By detecting these events early, society can prepare for the events, thereby reducing the amount of damage to people and property caused by the hazardous event.

Describe three properties of a frozen fruit bar including its state of matter.

Answers

The state of matter of a frozen fruit bar is solid. One property of solids is that they have a fixed shape, because the particles are tightly compressed and cannot move about. Another property is that solids can’t be compressed, because the particles have no space to move as a result of the compression. The frozen fruit bar has no free electrons so, like most other solids, it cannot conduct electricity.
