Fan and Medal!! Please check my answers!

The city is thinking about starting a program to add a new chemical to the public pool. Before they do, they want to find out if there are any health risks associated with this type of chemical. Which group would be the best to advise them on this topic?

A a group of concerned citizens who oppose the program
B the company that manufactures the chemical
C the local pest pool companies who would be hired to take care of the pool
D the government agency that regulates these types of chemicals

I think it's C.

Answer 1

The hybrid car uses battery power and gasoline to power the vehicle. This means that less gasoline is burned to power the vehicle. When burned, gasoline emits pollutants into the air. Evaluate the statements and choose the statement that best describes how this technology benefits the environment.

A Electricity is cheaper than gas; hybrid cars use more electricity generated by the battery they carry. Therefore, hybrid cars will save people money in fuel costs.
B Gasoline is a nonrenewable resource that, when burned, produces pollution that can harm the environment; therefore, because hybrid cars emit less pollution than regular cars, they do not cause as much damage to the environment.
C Hybrid cars are becoming more popular all the time. This means that sales of hybrid cars are going up. When sales go up, this creates jobs for people in our country and beyond.
D Hybrid cars run totally on a renewable resource. This means that as these cars become more popular, we will decrease our dependence on oil. Using less oil will reduce the amount of certain pollutants in the environment.

I think it's B.

Answer 2

Select the example that best describes a renewable resource.

A All the houses built in the new neighborhood had natural gas available, which will be used for cooking and heating.
B My town is powered by electricity that is generated by the energy from the flow of water through a large dam.
C Our lawn mower is powered by an engine that uses both oil and gasoline.
D The airplane can carry thousands of gallons of jet fuel needed to fly from New York to London.

I think it's B.

Answer 3

Select the sentence that best describes why plastics and rubbers are good insulators.

A In order for a material to be a good insulator, the electrons must be able to move freely into and out of the atom.
B Many materials like plastics and rubber do not have any loosely bound electrons in their outer shell making it difficult, if not impossible, for electrons to move between atoms.
C Plastics and rubber atoms have the same number of neutrons and electrons. This allows them to share electrons with other materials, allowing electric current to flow freely.
D The free flowing arrangement of the plastic and rubber atoms make them able to freely accept electrons and allow the flow of electricity.

I think it's B.

Answer 4

1 question at a time. :P

Answer 5

@jabez177 Can you check my answers though? I don't know if they are right

Answer 6

#4 I think you're correct but I'm guessing a different answer but at the same time your answer goes well... :/

Answer 13

@jabez177 What else do you think #4 could be? I wasn't sure about this answer either :)

Answer 14

I was thinking D because Rubber and Plastic are Insulators of electricity...

Answer 15

@jabez177 Oh, I thought that insulators didn't allow the flow of electricity

Answer 16

Hmmm... Let me search that up.
