Dmitri Mendeleev- arranged elements according to their

atomic mass

Johann Wolfgang Dobereiner-created groups of three elements,

each based on similar properties

John Newlands-used patterns to predict undiscovered

elements

Antoine Lavoisier-divided elements into four categories

Explanation:

The periodic table or the table depicting the arrangement of various elements has a long history. Several of the scientist starting from Lavoisier to Mendeleev contributed to the table in their might. The present table has been an evolution of the previous tables over their shortcomings.

Some of the notable contributions include-

Mendeleev- Mendeleev arranged the elements in order of atomic mass rather than atomic mass. Through this, he also discovered new elements.

Newlands- He formulated the Newland law of octaves similar to musical notation.

Lavoisier- Lavoisier divided the elements into various categories and also defined elements.

Dobereiner- He formulated the triad law which encapsulated that certain group of elements showed similar properties, hence can be grouped together.

wolverine [178]

Answer:

0.18216 T

Explanation:

N = Number of turns = 219

A = Area = $\pi r^2$

r = Radius = 1 cm

$\omega$ = Angular speed = $40\times 2\pi$

Maximum emf is given by

$\epsilon=NBA\omega\\\Rightarrow B=\dfrac{\epsilon}{NA\omega}\\\Rightarrow B=\dfrac{3.15}{219\times \pi 0.01^2\times 40\times 2\pi}\\\Rightarrow B=0.18216\ T$

The strength of the magnetic field is 0.18216 T
