Answer:
The sun uses nuclear fusion reactions to generate heat.
Explanation:
It is true from the given choices that the sun uses nuclear fusion reactions to generate heat.
The heat that accompanies nuclear fusion reactions is very huge. In fact this is the source of energy for the whole solar system.
During a nuclear fusion reaction, small atomic nuclei combines to form larger ones.
This combination results in a series of chain reactions that releases energy.
Answer:The strength of the gravitational force between two objects depends on two factors, mass and distance. the force of gravity the masses exert on each other.
Explanation: i hope it answers your question
" formation of a gas" Is the answer you are looking for this is because the chemical change can happen without freezing melting or boiling a substance
Measuring the temperature of the wall of the container as time passes
Answer:
Explanation:
I'm not sure what you mean by science, but I'll assume it's physics.
A trough, non scientifically is a narrow open container for animals to eat or drink out of.
Eg: The pigs drank water out of their small metal trough.
If you mean physics then the Trough is the lowest point on a wave.
Eg: The distance between two troughs on a wave was 14cm which is its wavelength.
Hope this helps :)
