Answer:
(b) Gravitational interactions with Jupiter
Explanation:
Gaps in the asteroid belt also known as Kirkwood Gaps are caused by the gravitational interaction between Jupiter and asteriods with Jupiter's orbital period. These Jupiter's orbital period occurs in a simple fraction, such as half, one-third, quarter etc.
Therefore, the correct option is "b" Gravitational interactions with Jupiter.
Answer:
40.4 kJ
Explanation:
The gas in this problem is in a sealed tank: this means that its volume is constant, so we can use the pressure law, which states that for an ideal gas kept at constant volume, the pressure is proportional to the temperature of the gas.
Mathematically:
where, in this problem:
is the initial pressure of the gas
is the final pressure
is the initial temperature
is the final temperature
Solving for T2,
Now we can find the change in internal energy of the gas, which is given by:
where:
n = 30 mol is the number of moles
R = 8.314 J/(mol • K) is the gas constant
And substituting the values of the initial and final temperatures, we get:
Answer:
Explanation:
1 )
Charge density of left plate
= - Q / A
Charge density of right plate
= + Q / A
2 )
capacitance c = ε₀ A / d
potential difference = charge / capacitance
= Q / [ ε₀ A / d ]
= Q d / ε₀ A
