Answer:
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
Answer:-81.29 J
Explanation:
Given
mass of ball 
Length of string 
height of Room 
Gravitational Potential Energy is given by

where h=distance between datum and object
here Reference is ceiling
therefore 
Potential Energy of ball w.r.t ceiling

i.e. 81.29 J of Energy is required to lift a ball of mass 2.35 kg to the ceiling
<span>The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas</span>
Can you please give the phrases?
But, I'll help what I can.
First, he was the first to discover gravity. He was not bonked by the head by an apple, rather he watched an apple fall from a tree before he decided to explore gravity further.
He was also the first scientist to be knighted, which is a great honor, as you can expect.
Newton also developed The Three Laws of Motion. They are extremely important to physics and are considered some of the foundation for physics today.
He also discovered calculus, which is complex math that is very helpful to scientists today.
He also discovered the color spectrum using a glass prism, a dark room and window shade with a hole in it. He was able to project the color spectrum onto a piece of paper.
Those are the few I can think of now, but hope it helps!
