Question

Due to meteors continually falling on Earth’s surface suppose an increase of mass of 0.002% without any change in radius occurs over a period of century. What change can this cause to the duration of day, the period of Earth’s spin ? 1) 0.002% decrease 2) 0.002% increase 3) 0.001% decrease 4) 0.001% increase

Answer 1

Answer:

Explanation:

As we know hat Earth is a Heavenly body and its mass will not increase that much from meteorites

Its angular momentum will be constant

Iw =const

2/5 MR² x 2π / T= const

As all except mas and time are cnst

M ∝ T

0.002% increase
