1. The problem statement, all variables and given/known data The potential at a point is 20 V. Calculate the work done in bringing a charge of 0.5 C to this point. 2. Relevant equations V = Ee / q W = -Ee 3. The attempt at a solution Ee = 10
Answer:
The second is correct.
Explanation:
Try with a magnet and experiment. You'll find out
Answer:
1. Sun-centered.
2.Both models.
3. Both models.
4. Sun-centered.
5.Both models.
6. Earth-centered only
7. Neither models.
Explanation:
Mercury goes through a full cycle phase. This is not sun-centered because the earth rotes from west to east,therefore objects in the sky moves east to west.
We sometimes see a crescent in Jupiter . These models cannot classify the observation because for an object to be seen as a crescent,the object must come between the earth and the sun.
Observation 3 and 5 can be classified with both models because the rise and set of all objects in the sky depend only on the rotation of the earth.
