Answer:
20 V
Explanation:
Power is 100 J/s or 100 W.
We know that P = IV =
.
Isolate the potential difference. V =
=
= 20 V
Circular Motion does occur on earth, so yes, true
For astronomical objects, the time period can be calculated using:
T² = (4π²a³)/GM
where T is time in Earth years, a is distance in Astronomical units, M is solar mass (1 for the sun)
Thus,
T² = a³
a = ∛(29.46²)
a = 0.67 AU
1 AU = 1.496 × 10⁸ Km
0.67 * 1.496 × 10⁸ Km
= 1.43 × 10⁹ Km
