Explanation:
The speed of the red car, relative to the blue car, is:
v = 75 m/s − 50 m/s
v = 25 m/s
One of Kepler's laws is that the orbits of planets are elliptical. It's not a suggestion.
BTW, circles are ellipses too, but so special that their likelihood is close to zero.
Answer:
Electromagnetic induction
Explanation:
The process of generating electric current with a magnetic field. It occurs whenever a magnetic field and an electric conductor move relative to one another so the conductor crosses lines of force in the magnetic field.
Same speed, because mass is neglected. The things that affect the speed are the distance and speed of the rock.
