Answer:
a
b
Explanation:
From the question we are told that
The position of the column of mercury in the barometer is \
The density of mercury is
Generally the pressure of the atmosphere at that column is mathematically represented as
=>
=>
Generally the atmospheric pressure at sea level (Generally the pressure before the change in level of the mercury column) is
Generally the change in air pressure is mathematically represented as
=>
=>
Generally the height which the column will rise to is mathematically evaluated as
Here is the density of water with value
So
=>
The answer is that all marine animals feed by seperating food particles from water, known as filter feeding.
Newton's new “reflecting telescope” was more powerful than ... Before Newton, scientists primarily adhered to ancient theories on ... laws of motion laid the groundwork for classical mechanics. Newton's research on motion helped give credibility to the heliocentric view. Newton also helped pioneer telescopic innovations, and he is sometimes credited with inventing the first reflecting telescope. He also conducted experiments using the prism, and developed a theory about the nature of color and light.
