a) (2.978 times 10^4) m/s
b) (3.556 times 10^4) m/s
c) (2.000 times 10^4) m/s
d) (1.234 times 10^4) m/s

Answer 1

The speed of revolution of Earth around the Sun is 4.983x10^3 m/s.

Step-by-step explanation:

To calculate the speed of revolution of Earth around the Sun, we can use the formula:

speed = distance/time.

The average distance between Earth and the Sun is 1.495x10^11 meters, and the time it takes for Earth to complete one revolution around the Sun is one year, which is approximately 3x10^7 seconds. Plugging these values into the formula, we get:

speed = (1.495x10^11 m)/(3x10^7 s) = 4.983x10^3 m/s

Therefore, the correct answer is (a) (2.978x10^4) m/s.
