Answer:
Volume of given mass of gas is inversely proportional to pressure of gas
Explanation:
Boyle's law: It states that the volume of given mass of gas is inversely proportional to the pressure of gas at constant temperature.
Mathematical representation:
Suppose, a gas of mass m
T=Constant temperature
V=Volume of gas
P=Pressure of gas
Then, 
The forces are in equilibrium.
Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that the period of revolution of the planet is given by

now we know that

T = 6.3 days

now we have


Part b)
As we know that mass of sun is given as

now we have


Hi!
Here’s your answer:
What happened to the combined energy of the two sleds when they collided? It changed forms into another energy C. Because energy is conserved, the “lost” energy has actually been changed into other forms.
Hope this helps have a good day!!<3
The answer would be:
The comb gains electrons.
The hair loses electrons.
In chemistry, the charge depends on the electrons and protons. The electron will give negative charge and proton will give the positive charge. Proton is located in the nucleus of the atoms so it won't easily move like electron which located in the orbit in the atoms perimeter. So, ignore the option with the proton.
If the combs become negatively charged, that means it gain some electron. Since something gain electron, that means another thing is losing an electron. That electron comes from the hair.
