What is a harmful effect of electrical resistance?

Answers

Answer 1
Answer: While voltage does pose a threat, it's mostly the current that causes damage. There must be voltage available to motivate electrons to flow through a victim. Resistance to current causes (in the case of the victim being human or having flesh) burnt tissues, muscles freezes, and fibrillates hearts.
Answer 2
Answer:

Answer:

Resistance resist the flow of current. This means that if 5V go through a resistance, it'll be reduce down to something below or equal to 5V.

If it gets reduce below 5V, lets say it goes down to 3V, the extra 2V must go somewhere. That 2V energy is converted to heat and dissipated through the resistor.

If there's a big current then the energy dissipated will be huge. And more negery = more heat which can cause fire and burn you.

imagine a computer monitor powered by electricity that has been generated by a wind turbine. Describe the types of energy involved

Answers

The computer monitor powered by electricity that has been generated by a wind turbine involves several types of energy.

The types of energy involved are as follows:

1. Kinetic energy:The blades of the wind turbine rotate and move due to the force of the wind. This motion or movement of the blades is referred to as kinetic energy.

2. Mechanical energy:The kinetic energy of the wind is converted into mechanical energy as the blades of the wind turbine rotate. This mechanical energy is then transferred to a generator which converts it into electrical energy.

3. Electrical energy:The mechanical energy from the wind turbine is converted into electrical energy by the generator. This electrical energy is then transferred to the computer monitor via electrical wires.

4. Potential energy:As the wind turbines blades move, they gain potential energy. The potential energy is the energy that an object has due to its position or condition. The blades of the wind turbine gain potential energy as they move higher and higher due to the wind force. This potential energy is converted into kinetic energy as the blades rotate.

Thus, there are 4 types of energy involved in computer monitor powered by electricity that has been generated by a wind turbine.

How can understanding change of state help you to seprate a salt water solution

Answers

Answer: You can apply the fact that water changes from liquid to gas when heated to its boiling point.

Explanation:

Salt solution contains salt dissolved in water. The water can be separated from the salt by evaporation of the solution to dryness. This exploits the fact that water changes from liquid to gas at it's boiling point. This is an example of change of state. When heated strongly, all the water present will be converted to vapour and the solid salt reappears.
Because if you wanted to separate the salt from the solution, you will have to know the boiling point of the water. Since one way is to evaporate water from salt, which means you boil the water and leave all the salt behind, you have a solid left, which is the salt. You had to know that water can be evaporated because it is a liquid.

The three states of matter are:
-Solid
-Liquid
-Gas

What do physical changes do?

Answers


Great question!

Physical changes change the appearance of something or someone.

For example, let's say 2 cats get into a fight. One is left clean in the end of this, with no scratches or bites anywhere, so nothing has happened to it as a physical change.

However, the other cat is left scarred and with bite marks everywhere. All this has left the cat's once-beautiful coat now ragged and torn up. This is an example of a physical change.
