Discussion: 1. Describe how the distance between the Earth and the Sun changes when the Earth
makes a complete orbit around the Sun.
2. Discuss how the shape of the Earth's orbit would be if the major axis is almost as long
as the minor axis.

The duration of a photographic flash is related to an rc time constantly

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
