Answer:
2.5
Explanation:
A.
Electrical energy turns the rod. This energizes the coil. The magnetized coil generates an electric current. The electric current goes through the wires to power the lightbulb.
B.
Mechanical energy turns the rod. This electrifies the coil. The electrified coil generates a magnetic field. The magnetic field goes through the wires as electricity to power the lightbulb.
C.
Mechanical energy turns the rod. This magnetizes the coil. The magnetized coil generates an electric current. The electric current goes through the wires to power the lightbulb.
D.
The magnetic energy in the coil turns the rod. The rod generates an electric current. The electric current goes through the wires to power the lightbulb.
b. Jupiter
c. Uranus
d. Neptune
The answer is Jupiter not neptune :)
A chlorine ion contains 17 protons and 18 electrons, which gives it a net charge of -1 1234. Therefore, the correct answer is A. -e.
B) because the air pressure is significantly higher when it is colder
C) because the molecules in the balloon have slowed down with the temperature
D) because the molecules shrink in size when exposed to the colder, outside air
Answer: Option (C) is the correct answer.
Explanation:
When the balloon was placed inside Tamika's classroom then the temperature was high as compared to the temperature outside the classroom.
As a result, gas molecules were in rapid motion but when balloon was placed outside the classroom then due to cold, there was decrease in temperature.
Therefore, the movement of gas molecules will slow down and the molecules will come slightly close to each other.
Hence, there will be shrinkage in the size of balloon.
Thus, we can conclude that the balloon has gotten a little bit smaller because the molecules in the balloon have slowed down with the temperature.
