Question

the Earth revolves around the sun in a circular path with a speed of 30 km per second what is a radial acceleration directed towards the sun​

Answer 1

Answer:

Explanation:

Hey,

The solution of your query is as following,

=> Here, the Earth revolves around the sun in a circular path with a speed of 30 km per second

Speed of revolution = 30 km/s = 3 * 10⁴ m/s.

Time of revolution = 1 year = 365 * 24 * 60 * 60 = 3.15 * 10⁷ sec

=> Radial acceleration, a_c = v₂/ r

Distance covered by Earth = circumference of orbit

V.T = 2πr

r = V.T / 2π

∴ a_c = v² / r

= v² 2π / v T

= 2πV / T

= 2π * 3 * 10⁴ / 3.15 * 10⁷

= 5.98 * 10⁻³ m/s²

Thus, a radial acceleration directed towards the sun​ is 5.98 * 10⁻³ m/s².
