Did Hooke discovered Uranus?
3. He discovered the planet Uranus and other important astronomical elements. Hooke was responsible for building one of the first Gregorian telescopes. With this telescope, he made the first known description of the planet Uranus.

What does F KX mean?
F = kx. F is the force applied to the spring in newtons (N) k is the spring constant measured in newtons per meter (N/m) x is the distance the spring is stretched from its equilibrium position in meters (m) The Hooke's Law Apparatus. What causes elasticity?
The physical reasons for elastic behavior can be quite different for different materials. In metals, the atomic lattice changes size and shape when forces are applied (energy is added to the system). For rubbers and other polymers, elasticity is caused by the stretching of polymer chains when forces are applied. Which material is more elastic?
steel
What is the most elastic material in the world?
rubber

What is elasticity material?
Elasticity is the tendency of solid materials to return to their original shape after forces are applied on them. When the forces are removed, the object will return to its initial shape and size if the material is elastic. Who made Hooke's Law?
Hooke's law. Hooke's law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. Why is steel elastic?
By this definition, steel is more elastic than rubber because steel comes back to its original shape faster than rubber when the deforming forces are removed. For a given stress (stretching force per unit area) strain is much smaller in steel than in rubber and hence the answer. Who is father of cell?

How did Hooke change the world?
Hooke used his microscope to observe the smallest, previously hidden details of the natural world. His book Micrographia revealed and described his discoveries. Hooke discovered the first known microorganisms, in the form of microscopic fungi, in 1665. Who are the 5 scientists who discovered cells?

What is the law of elasticity?
Hooke's law, law of elasticity discovered by the English scientist Robert Hooke in 1660, which states that, for relatively small deformations of an object, the displacement or size of the deformation is directly proportional to the deforming force or load. Why does no one know what Robert Hooke looked like?
Some people disputed his diagrams because they refused to believe what they showed. The world Hooke had discovered was too alien for them! He thought the objects he had discovered looked like the individual rooms in a monastery, which were known as cells. Hooke did not discover the true biological function of cells. What is K in Hooke's Law?
Mathematically, Hooke's Law can be written as F=-kx. Many materials obey this law as long as the load does not exceed the material's elastic limit. The rate or spring constant, k, relates the force to the extension in SI units: N/m or kg/s2. Why is Hooke's Law negative?
where the minus sign shows that this force is in the opposite direction of the force that's stretching or compressing the spring. In Hooke's law, the negative sign on the spring's force means that the force exerted by the spring opposes the spring's displacement. What is spring constant?
spring-constant. Noun. (plural spring constants) (physics) A characteristic of a spring which is defined as the ratio of the force affecting the spring to the displacement caused by it. How is Hooke's Law calculated?
Hooke's Law states that the force needed to compress or extend a spring is directly proportional to the distance you stretch it. As an equation, Hooke's Law can be represented as F = kx, where F is the force we apply, k is the spring constant, and x is the extension of the material (typically in meters). How did Leeuwenhoek discovered bacteria?
He built a simple microscope during 1671 and started observing different substances. He experimented to calculate the number of microorganisms in water and examined other objects like skin, hair and blood. He also studied physical structure of ivory and discovered parasites in flea using more powerful microscopes. What is Hooke's Law Class 11?
Hooke's law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body. As a result stress develops in the body due to this stress there will be a strain produced in the body which implies that there will be some deformation in the body. What is Hooke's Law graph?
Hooke's Law. The extension of a spring or wire is directly proportional to the force applied provided the limit of proportionality is not exceeded. When a graph of force against extension is plotted for a material which obeys Hooke's law it looks like the graph below. Why is Hooke's law important?
Hooke's Law, by Doodle Science, on youtube.com Hookes law is important because it helps us understand how a stretchy object will behave when it is stretched or compacted. The main component of car shocks are springs, and understanding how the spring will behave (using hookes law) is ideal for enhancing the technology. Where did the word cell come from?
1665: Robert Hooke discovered cells in cork, then in living plant tissue using an early compound microscope. He coined the term cell (from Latin cella, meaning "small room") in his book Micrographia (1665). What are the 3 parts of the cell theory?
The three parts of the cell theory are: cells are the smallest unit of life; all cells come from preexisting cells; and living thing is made up of one or more cell. What did Hooke look like?
What did Robert Hooke look like? A new portrait the great enlightenment scientist Robert Hooke is to be hung at the Institute of Physics in London, a recreated likeness after his only portrait was destroyed in a fire, some say at the hands of his rival Isaac Newton. What is Hooke most famous for?
Robert Hooke was a famous scientist, born in 1635. He most famously discovered the Law of Elasticity (or Hooke's Law) and did a huge amount of work on microbiology (he published a famous book called Micrographia, which included sketches of various natural things under a microscope). How did Hooke find cells?
Robert Hooke (July 18, 1635–March 3, 1703) was a 17th-century "natural philosopher"—an early scientist—noted for a variety of observations of the natural world. But perhaps his most notable discovery came in 1665 when he looked at a sliver of cork through a microscope lens and discovered cells. Where did Hooke discover cells?
Hooke had discovered plant cells -- more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term "cells": the boxlike cells of cork reminded him of the cells of a monastery. Hooke also reported seeing similar structures in wood and in other plants. How did Hooke observe cork cells?
Hooke cut a thin slice of cork with a penknife, put it under his microscope, focused sunlight on it with a thick lens, and looked through the eyepiece. What Hooke saw looked like a piece of honeycomb. The cork was full of small empty compartments separated by thin walls. What does the cell theory State?
The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells. Rudolf Virchow later made important contributions to this theory. The cell is the fundamental unit of structure and function in living things.
