A would be the answer because thats how long it takes
Answer:
Explanation:
The formula that relates the luminosity of a star (L) to its radius (R) and the temperature (T) is
For star B, we can write:
For star A, we have
So the luminosity of star A is
Slightly downstream for the shortest possible time
Answer:
The acceleration due to gravity in planet Pud is of 9345.7m/s²
Explanation:
Since the probe is describing a circular motion around planet Pud, its centripetal acceleration is given by the formula:
Assuming there is no other external forces acting on the probe in the centripetal direction, we have that
Before we plug in the values, we have to convert the speed from km/s to m/s:
Finally, using the given values, we can compute g_{Pud}:
In words, the acceleration due to gravity in planet Pud is of 9345.7m/s²
