Answer:
fossil fuels are natural and limited, nuclear is man made and more toxic
Explanation:
Answer:
Explanation:
1 psi = 6894.76 Pa
P = 184 psi = 12.686 x 10⁵ Pa .
Temperature T = 95⁰F = 35⁰C= 308 K
volume V = 18 ft³ = 18 x 0.0283168 m³
= .51 m³
From the gas law
PV/RT = n where n is mole of gas
= 12.686 x 10⁵ x .51 / 8.31 x 308
= 252.78 gm mole
= 252.78 x 32 gm
= 8.08896 kg
= 2.20462 x 8.08896 lb
= 17.833 lb
= 17.833 / 32 lbf
= .5573 lbf
weight of tank = 150 lbf
Total weight = 150 + .5573
= 150.5573 lbf .
Answer:
Approximately 
.
Explanation:
The net force on the girl would be:
.
Under the assumptions, the net force on this girl would be equal to the tension force in the rope. All other forces on the girl would be balanced.
In other words, the tension force that the rope exerted on the girl would be 
. The girl would exert a reaction force on the rope at the same magnitude (
) in the opposite direction. This force would translate to a 
force on the boy towards the girl.
Under similar assumptions, the net force on the boy would also be . Since the mass of the boy is 
, the acceleration of the boy would be:
.
Answer: The volume of the gas increases as the temperature increases. As temperature increases, the molecules of the gas have more kinetic energy. therefore it increases! Hope this helps you!
