Q.4 (1 mark): The period of the Earth's orbit around the Sun, which we know is one year, and the radius of the Earth's orbit around the Sun is 1.496 x 10" m. We will model the Earth as a particle and approximate the Earth's orbit as circular. The centripetal acceleration of the Earth as it moves in its orbit around the Sun is: A) 5.93 x 103 m/s. B) 5.93 x 10 m/s. C) 5.93 x 103 m/s2. Page 2 of 9
