Streams carry sediment, like pebbles, in their flows. The pebbles can be in a variety of locations in the flow, depending on it's size, the balance between the upwards velocity on the pebble (drag and lift forces), and it's settling velocity.

A 2.35 kg ball is attached to a ceiling by a3.53 m long string. The height of the room is5.03 m .The acceleration of gravity is
Studentka2010 [4]

Answer:-81.29 J

Explanation:

Given

mass of ball m=2.35 kg

Length of string L=3.53 m

height of Room h=5.03 m

Gravitational Potential Energy is given by

P.E.=mgh

where h=distance between datum and object

here Reference is ceiling

therefore h=-3.53 m

Potential Energy of ball w.r.t ceiling

P.E.=2.35\times 9.8\times (-3.53)=-81.29 J

i.e. 81.29 J of Energy is required to lift a ball of mass 2.35 kg to the ceiling

Which phrase best describes sir isaac newton's contributions to modern science and therefore to the industrial revolution?
MrMuchimi
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!
