In response to this question, I calculated the answer to this question, if we were at the equator, where the change would be greatest: https://socratic.org/questions/5667107b7c01493f09503ec0?source=search
It turns out that the rotational motion's contribution is about
Explanation:
Acceleration due to gravity at a latitude (
#"g"_(phi) = "g"_"e" - "R"ω^2cos^2(phi)#
where
#"g"_"e" =# Acceleration due to gravity at equator#"R ="# Radius of Earth#ω =# Angular Velocity with which earth is rotating#phi =# Angle between the equatorial plane and the line joining the point where acceleration due to gravity is#"g"_phi# to the centre of the earth. It ranges from#0°# at equator to#90°# at poles.
When Earth was rotating
#"g"_1 = "g"_"e" - "R"ω^2cos(phi)#
Note:
When Earth stops rotating
#"g"_2 = "g"_"e" - 0#
#"g"_2 = "g"_"e"#
In second case we are not subtracting any term from

Use mathematical induction to prove the truth of each of the following assertions for all n ≥1
Use mathematical induction to prove the truth of each of the following assertions for all n ≥1. 5^2n – 2^5n is divisible by 7 If n = 1, then 5^2(1) - 2^5(1) = -7, which is divisible by 7. For the inductive case, assume k ≥ 1, and the result is true for n = k; that is 7 | (5^2k + 2^5k). U...
