Answer: Isaac Newton
Explanation: Isaac Newton is popularly remembered as the man who saw an apple fall from a tree, and was inspired to invent the theory of gravity. If you have grappled with elementary physics then you know that he invented calculus and the three laws of motion upon which all of mechanics is based.
-- ends of the swing . . . . . all potential energy, no kinetic
-- middle of the swing . . . . all kinetic energy, no potential
-- Potential energy and kinetic energy are equal at the points
(one on each side of the swing) where the bob is at a height
that is midway between the height at the end of the swing and
the height at the bottom of the swing.
Answer:2
Explanation:
Given
and 
and 
are the acceleration of 1 and 2
Suppose T is the Tension
then for block 2
For block 1
equate 1 and 2
where 
thus we can see that a is less than g
therefore 
The statement ‘An advantage of
electron microscopes compared to light microscopes is that electron microscopes
are inexpensive and commonly used in most biology laboratories allow you to view living cells, while light microscopes
do not have higher resolution that allows you to view smaller specimens allow
you to view the true colors of the specimens being viewed’ is true. In fact,
electron microscope is more efficient than a light microscope due to its
mechanism using only light without magnifying the specimen a thousand times.
