Let me think I think it’s B
Read through it carefully,
1400J of "heat" was added to the system
only 600J of thermal energy was added to the system, or only 600J of the "heat" was used to change the temperature
so if only 600 of 1400J was used to affect the temperature, that means the remaining heat energy must have been converted to work
1400J-600J =
The Sun <span>produces energy by forming "Helium" in its core by the process of "Nuclear fusion"

Answer:
1.41 m/s, 7.85 rad/s
Explanation:
We can start by calculating the tangential velocity, which is given by:
where
r = 18 cm = 0.18 m is the radius of the circumference
T = 0.8 s is the period
Substituting,
Now we can also calculate the angular velocity, which is given by:
where again,
T = 0.8 s is the period
Substituting,
