Which best explains why a firework being ignited is an example of an exothermic reaction and not an endothermic reaction?
The fireworks produce colors.
The fireworks give off heat.
Igniting the fireworks requires energy.
Igniting the fireworks makes an odor.
Answer:
B. Fireworks give off heat.
As the firework releases heat, it is considered as exothermic reaction. The correct option is B.
What is exothermic reaction?An exothermic reaction has been one in which the energy has been required to break bonds in the reactants has less than the energy released when the new bonds form in the products. Energy has been constantly released during an exothermic reaction, often in the form of heat. Exothermic reactions has been characterize all the combustion reactions.
Endothermic reactions has been known as the chemical reactions that produce products by absorbing heat energy from their surroundings. Exothermic reactions has been important in the forensic science, particularly in the investigation of the fires and explosions.
Endothermic has been refers to the chemical reaction that it requires heat and results in the cooling of the surroundings. As fireworks are the releasing energy in the form of the heat, it can be called as an exothermic reaction.
Therefore, As the firework releases heat, it is considered as exothermic reaction. The correct option is B.

What is the measurement of this square?
A.075
B. 1.75
C. 0.34
Answer:
0.75 in
Explanation:
The 1 inch measure has 16 divisions.
Find the measure of 1 division as: 1/16 = 0.0625 in
The side length of the square has 12 divisions
1 division = 0.0625 in
12 divisions = 0.0625*12 = 0.75 in
The correct answer choice is A. 0.75.
Answer choices B is incorrect because from the diagram, it is clear that the side length of this square is less that 1 inch.
Answer choice C is incorrect because 0.34 in will mean 0.34/0.0625 divisions. This is 5 divisions, yet the square side length covers 12 divisions.

I NEED THIS DONE ASAP!!!!!! List 4 materials that would light up this light bulb when dropped onto the crocodile clips. In 1-2 sentences, describe why it caused the light to turn on using these 4 key terms: conductor, circuit, electrons, flow.
Answer:
The four items are;
1) Nail, 2) Screw, 3) Key, 4) Scissors
Explanation:
The given electric circuit consist of two batteries that provides electromotive force to help transfer electrons and result in the flow of an electric current when the circuit is completed by providing a conducting path through the crocodile clips. By dropping either of the nail, screw, key or scissors, onto the crocodile clip, the circuit is completed and current is allowed to flow through the circuit, passing through the light, causing it to turn on.

After reading the following paragraph, what conclusion most accurately characterizes a police officer’s career?
After graduation from the police academy, some police agencies provide police training officer, or PTO, programs. PTO programs focus on many phases of training, each focusing on some aspect of the policing process. Problem-based learning, critical thinking, problem solving, and teamwork are also emphasized. Throughout a police officer’s career, training continues to occur. Called in-service training, this training helps to sharpen the officer’s skills and improve the quality of police work that an officer can provide to the community. Some of this training covers skills like firearms training or self-defense, but a wide choice of electives can be chosen, as well. These electives include computer and equipment skills, interview and interrogation skills, domestic violence, problem-solving skills. Most police agencies require that their officers participate in in-service training every year. Training can be tailored to the particular needs of the department’s officers, so that the skill set of each officer is developed to meet needs of the community.
A police officer will be given more legal jurisdiction over time
A police officer will be given more authority over time
A police officer will repeat many stages of training
A police officer will be engaged in lifelong learning and training

Scroll saw blades break
O very seldom
O when forcing the wood through the blade
O when dull
Answer:
when forcing the wood through the blade
Explanation:
Scroll saw blades are used for making delicate curves through the woods, especially when making edges. These are pedal-operated and are considered as power tools.
Nevertheless, it is also common for some people to break their scroll saw blades. The number one reason behind this is the force or tension caused by forcing the wood through the blade. Thus, it is very important to learn the trick of applying appropriate pressure when using this tool.

Which construction material can workers erect at the fastest rate?
____ is the fastest construction material to erect.
Answer:
Onsite construction can certainly begin more quickly when you are using concrete, stone, or brick. However, total construction time will lag behind that of building with steel. These materials require time to prepare and cure; and they result in more waste to move off site and dispose of.

A refrigerator operates on a average of 10 hours a day. If the power rating
of the fridge is 700 w how much electrical energy does the fridge use in one day
Answer:
60480 kW
Explanation:
The first step in calculating energy consumption is to know how many watts your device consumes per day.
The refrigerator operates on average of 10 hours per day.
The refrigerator ratings is : 700 w , this means 700 joules per second
1 second = 0.000277778 hours
? seconds= 10 hours
Perform cross product as;
( 10 * 1) / 0.000277778 = 36000 seconds
So,
700 joules = 1 second
? = 36000 seconds
Perform cross product as;
( 700 * 36000) /1 = 25,200,000 joules
25,200kW = 10 hours
? = 24 hours -----for 1 day
(25,200 * 24 )/10
=60480 kW
