Explanation:
Period of a mass on a spring is:
T = 2π√(m/k)
T is directly proportional with the square root of m. So as the mass increases, the period increases.
When iron is exposed to moisture and oxygen it starts to rust.
Answer: The elimination of seasonal variations
Explanation:
Since the cosmic catastrophic event which occurred led to the tilt of the Earth's axis relative to the plane of orbit to increase from 23.5° to 90°, the most obvious effect of this change would be the elimination of seasonal variations.
It should be noted that seasonal variation refers to the variation in a time series that's within a year which is repeated. The cause of seasonal variation can include rainfall, temperature, etc.
Answer:
The strength of gravity decreases.
An example of that would be if you were in space; you float around because there's no gravity.
