I’m pretty sure it c hope that helped

Answer:

E. A conductor is needed for electricity to flow in a circuit.

Explanation:

Electric current can flow without a resistor, as in short circuit.

A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance.

Without a switch, electricity can flow in a circuit, switch is only used to close or open the circuit.

Thus, the only correct option is  E

E. A conductor is needed for electricity to flow in a circuit.

Answer:

Informercials, like the class Shamwow Informercial are an example of how structure and technique can have a huge effect on how a user or prospect is driven towards taking a specific action like clicking a buy button.

Informercials follow a specific structure that any small business can use to drive action but few businesses ever consider using it when they pitch their product or service. In this post, we'll describe the structure and give you examples of how you can use it in your business.

The question above wants to test your ability to create an infomercial using your creativity. For that reason, I can't create an infomercial for you, but I'll show you how to create one.

First, you need to know that an infomercial is an advertisement made to be played on television, usually associated with sales, but can be used to present information.

Based on this, you should create your newsletter as follows:

Establish the element that your infomercial wants to present.Show what are the issues related to this element.Show the solutions you want to present to these problems.Show how these solutions are truthful and reliable.

In the image below, you can see a tutorial on how to make an infomercial.

a sample of alcohol has a density 0.82 g/ml.what is the mass of 5500 mL of the alcohol

Answers

Answer:

The answer is 4510 g

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

mass = Density × volume

From the question

density = 0.82 g/mL

volume = 5500 mL

We have

mass = 0.82 × 5500

We have the final answer as

4510 g

Sentence Starters

"Potential Energy is. . "

"Kinetic Energy is. . "

"The difference between potential energy and kinetic energy is. . ."

Answers

Answer:

Potential energy is the stored energy in an object or thing, while kinetic energy is the energy which an object contains because of a particular motion.

Explanation:

Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.

The difference is that potential is stored and kinetic is moving energy.
