12. In the equation for the speed of an object in circular orbit, what does m represent in this equation?
-
The mass of the sun
-
The mass of Earth
-
The mass of the central object
-
The mass of the orbiting object
Correct Answer
A. The mass of the central object -
- 4.
In the figure, according to Kepler’s laws of planetary motion,
-
A1 = A2.
-
Delta t1 > delta t2.
-
If delta t1 = delta t2, then the orbit is circular.
-
If delta t1 = delta t2, then A1 = A2.
Correct Answer
A. If delta t1 = delta t2, then A1 = A2. -
