Your answer would be C, "By conserving energy"! A gas can do work through something called the First Law of Thermodynamics. Heat that energy used by the gas during this "work" cannot be created or destroyed however it can be transferred and converted. This energy can only be stored during these processes, not removed. An example of this would be gas in a cylindrical object such as a piston. When the gas is heated, it expands and moves the piston upwards. When it expands, it stores that energy it gains through the heat given.

Question
If Star A and Star B have the same absolute magnitude, but Star A is brighter, what does that tell us?
Solution 1
We can conclude that star A is closer to us than star B.
In fact, the absolute magnitude gives a measure of the brightness of the star, if all the stars are placed at the same distance from Earth. So, it's a measure of the absolute luminosity of the star, indipendently from its distance from us: since the two stars have same absolute magnitude, it means that if they were at same distance from Earth, they would appear with same luminosity. Instead, we see star A brighter than star B, and the only explanation is that star A is closer to Earth than star B (the closer the star A, the brigther it is)

Question
How does inertia affect a person who is not wearing a seatbelt during a collision?
Solution 1
An object in motion tens to stay in motion so if one is not wearing their seatbelt they will be thrown across a car or even out of the car. The car is in motion and so is the perso in it so when it hits somthing the car stopes but the person does not because they are not wearing their seatbelt.
Question
an electric dryer consumes 6000000 joules pf electrical energy when operating at 220 volts for 1800 seconds. during operation, the dryer draws a current of
Solution 1
6000000 joules = 6000000watt-seconds
6000000 w-s / 1800s = 3,333 watts
3333 / 220 volts = 15.151515 Amps
15A
6000000 w-s / 1800s = 3,333 watts
3333 / 220 volts = 15.151515 Amps
15A
Question
Calculate the total electric flux leaving the cubical surface formed by the six planes x, y, z = ±5 if the charge distribution is: (a) twopoint charges, 0.1 μC at (1,− 2, 3) and 17μC at (−1, 2,−2)
Solution 1
If I correctly recall my E&M studies from 1958,
I suspect that this is a chump question.
The E flux through ANY closed surface is equal to the net
charge inside, or maybe it's the net charge divided by ε₀ .
Yep, I think that's it.
Your charges are both positive, so if they're inside your cube,
the net charge inside will be 17.1μC .
Your cube has all faces 5 units from the axes, and neither charge
has an x, y, or z component with absolute value greater or equal
to 5. So both charges are well inside the cube.
Seems to me, then, like the total E flux through the cubical
surface is
17.1μC / ε₀ .
I don't really care whether this is helpful or not.
I just hope it's correct.
Question
An object in free fall moves at the same speed with time and does not accelerate. True
False
Solution 1
False, what your thinking of is terminal velocity. Free fall is different, while an object is in free fall the only force acting on it is gravity, if an object is in free fall it will eventually accelerate to terminal velocity.
Solution 2
True, this is called terminal velocity
