Answer:
A=False
B=False
C=False
D=False
E=False
F=False
Explanation:
A. In an isothermal process, only the reversibly heat transfer is 0, ![Q_{rev}=T (\Delta S)](https://tex.z-dn.net/?f=Q_%7Brev%7D%3DT%20%28%5CDelta%20S%29)
B. Consider the phase change of boiling water. Here, the temperature remains constant but the internal energy of the system increases.
C. This is not true even in reversible process, as can be inferred from the equation in part A.
D. This is only true in reversible processes, but not in all isothermal processes.
E. Consider the phase change of freezing water. Here, the surroundings are increasing their entropy, as they are taking in heat from the system.
F. This is not true if
, like in answer B. One case where this is true is in the reversible isothermal expansion (or compression) of an ideal gas.

Explanation:
What is the acceleration of a 0.75 kg vehicle powered by 0.05 N of force?
A) 0.0875 m/s^2
B) 0.067 m/s^2
C) 0.375 m/s^2
D) 11.4 m/s^2
Answer:
Put a 10.0-ohm resistor in the circuit. Measure the current in the circuit. Replace the 10.0-ohm resistor with a 20.0-ohm resistor. Measure the new current. Continue replacing the resistor with a different resistor of known resistance. Measure the current for each resistor. Record all data.
Explanation:
The only design that has resistance varying with everything else remaining the same is the first design. That would be what you'd want to do if you're exploring the effect of resistance on current.
