17th Century
In 1661 he founded a scientific society which later became known as the Royal Society of England. Traditional Chemistry - The Mid 17th Century to mid 19th Century By this time scientists were using the "modern method" of discovery by testing theories with experiments.
At the time of the Fall equinox (always near September 21),
and the Spring equinox (always near March 21), the days and
nights are nearly the same duration.
The shortest days of the year are around the Winter solstice ...
always near December 21.
The longest days of the year are around the Summer solstice ...
always near June 21.
Eclipses can happen on any day or night of the year. They're
totally not connected with the equinoxes or solstices.
Answer:
Explanation:
given,
mass of solid sphere = M
radius = R
linear speed = v
now,
Linear Kinetic energy
...............(1)
Rotational kinetic energy
moment of inertia of the solid sphere
and v = R ω
............(2)
ration of rotational and Kinetic energy
hence, ratio of rotational to linear kinetic energy is equal to 2/5.
