Answer:
c) There are sharp emission lines demonstrating discrete energy levels.
Explanation:
When an element emits energy in the form of radiation, it produces a spectrum of colors on a photographic plate. This spectrum can either be continuous or discrete. In continuous spectrum the spectrum continues without any discrimination between two regions. This represents the continuous emission of radiation, and thus the continuous emission of energy without any break.
On the other hand, the line spectrum consists of discrete and sharp lines, which shows the emission of radiation in a certain amount in a certain time, with a break between emission. Hence, the line spectra supports the quantization of energy.
The correct option is:
c) There are sharp emission lines demonstrating discrete energy levels.
Create a sort of infomercial featuring a solution you created or designed.
Say a few statements about it.
please help
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.

Mr. Bullis wants to know if he gives teachers candy, it will make them smile more. He gives half the teachers candy and the other half get nothing. He then records the number of times the teachers smiled.
Experimental Group:
Control Group:
Answer:
the experimental group would be the teachers who recieved the candy
control group would be the teachers who dont get any candy
Explanation:
experimental group is the group that receives the test variable being tested in this case the variable being the candy
and the control group is the group who doesn't receive the variable
purpose of having a control is to rule out other factors which may influence the results of an experiment.

Why do acids and bases neutralize eachother?
Answer:
Explanation:
When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water. The compound formed by the cation of the base and the anion of the acid is called a salt.
Luciana explains to Eric how electricity flows in a circuit. Which sentences are a part of her explanation? Select all that apply.
A. Without a resistor, electricity cannot flow in a circuit.
B. Without a switch, electricity cannot flow in a circuit.
C. For electricity to flow in a circuit, the circuit must be complete.
D. An insulator such as plastic is needed for electricity to flow in a circuit.
E. A conductor is needed for electricity to flow in a circuit.
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.
A dark blue beaker labeled 100 millimeters Y has an arrow leading to a pale blue beaker labeled 99 millimeters H subscript 2 O. This has an arrow leading to a white beaker labeled 99 millimeters H subscript 2 O. Each arrow has a label 1 milliliter over it. The dark blue beaker has a box below it labeled Beaker number 1. The pale blue beaker has a box below it labeled Beaker number 2. The white beaker has a box below it labeled beaker number 3.

Explain the difference between potential energy and kinetic energy.
Sentence Starters
"Potential Energy is. . "
"Kinetic Energy is. . "
"The difference between potential energy and kinetic energy is. . ."
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.
a sample of alcohol has a density 0.82 g/ml.what is the mass of 5500 mL of the alcohol
Answer:
The answer is 4510 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density = 0.82 g/mL
volume = 5500 mL
We have
mass = 0.82 × 5500
We have the final answer as
4510 gHope this helps you
