From Boyle's law, the volume of a fixed mass of a gas is inversely proportional to its pressure at constant absolute temperature.
Therefore; P1V1 =P2V2; where PV is a constant
hence; 12 × 6 = 3× p2
p2 = 72/3
= 24 atm
Therefore; the new pressure will be 24 atm
Answer:
The potential energy of the hiker is .
Explanation:
Given that,
Mass of the hiker, m = 61 kg
Height above sea level, h = 1900 m
We need to find the potential energy associated with a 61-kg hiker atop New Hampshire's Mount Washington. The potential energy is given by :
g is the acceleration due to gravity
So, the potential energy of the hiker is . Hence, this is the required solution.
When the suns energy moves through space it reaches earths atmosphere and finally the surface it warms the atmosphere and becomes heat energy then its transfared throughout the planets system by radiation conduction and convection
Answer:
472.36 N
Explanation:
The total mass with the tire and child would be 45 kg + 3.2 kg = 48.2 kg
Ft = force tension
Fg = force of gravity
Fnet=0 (because child is motionless and not accelerating)
0 = Ft - Fg
Ft = Fg
Ft = m*g
Ft = 48.2 kg * 9.8 m/s^2
Ft = 472.36 N
Hope this helps!!
Explanation:
The Dalton's atomic theory was proposed by John Dalton in the 19th century through his experiment on gases. Some of his propositions are;
- Atoms are the smallest indivisible particles of matter and they can neither be created nor destroyed.
- Elements have identical atoms that are different from atoms of other elements.
- Atoms vary in size and mass for different elements and this distinguishes them from atoms of other elements.
- Whole number combination of atoms results in the formation of compounds.
- Compounds are formed in chemical reactions when atoms recombine with one another.
You can compare your options with any of the statements above.
