The contribution to the nature of light-

Thomas Young - wave nature of light (double-slit experiment)

Max Planck - E = hv

Albert Einstein - a quantum theory of light

Thomas Young proposed the most important double-slit experiment which shows that light acts like a wave and shows the pattern of interferences.

Max Planck proposed that light is proportional to frequency. He gave the equation, E = hv, where E is the energy of light, h is Planck's constant, and v is the frequency.

Albert Einstein proposed the quantum theory of light. He determined that light exists in discrete quanta of energy called photons.

bearhunter [10]
Out of the options given above, the statement that is true is this: YOU ARE EXPOSED TO NUCLEAR RADIATION EVERYDAY.
Man is naturally surrounded by many natural  and artificial radioactive sources which give out radiations on a daily basis. Although most people believe that the natural radiation are at levels that are not dangerous, scientific studies had found out that this is not true; some of the radiations are given out at the rate that are harmful to humans.<span />

How much time is required to plate out 20.0 g of Zn from a solution containing Zn2+ ions, using a current of 2.00 amperes?
lyudmila [28]

Answer: 494.872mins

Explanation:

M= MrIt÷n

M=20g

Mr=65g/mol

I=2A

1 farad= 96500

For zinc with 2ions

2×96500= 193000

M×n= MrIt

T= M×n÷MrI

t= 20×193000/2×65

t= 3860000/130

t= 29692.307sec

t=29692.307/60

t= 494.872 mins

E What caused the little puddle of water to appear under the syringe tip? its for sciences ​
fredd [130]

LMBO, for science.

Answer:

<em>The increase in kinetic energy leads to leakage of water from the syringe. When the outside temperature is more than the liquid temperature, say the syringe is out in sunshine, then the liquid becomes slightly warmer.</em>

How many atoms of zinc are in 0.60 mol of zinc? 2. how many moles is 3.52 × 1024 molecules of water? 3. how many atoms are in 2.
Veronika [31]
  question 1
 by use  of Avogadro  law
that is,1 mole = 6.02  x10^23 atoms
  what  about  0.60  moles  
by use of cross multipication

=(0.60 mole/ x 6.02 x10^23)/ 1mole = 3.612 x10^23 atoms of Zn

question  2
by  use  of Avogadro  law  constant
that  is 1 mole  =6.02  x10^23  molecules
what  about 3.52 x10^24  molecules
by cross  multiplication
=( 1 mole x3.52 x10^24 molecules/6.02 x10^23  molecules)  = 5.847  moles of water

question 3

by  use  of Avogadro  law  constant
1 mole = 6.02 x10^23 atoms
what about  2 moles =? atoms
by use of cross  multiplication
=( 2moles  x 6.02 x10^23 )/1mole= 1.204 x10^24  atoms  of Li

question 4

by  use  of Avogadro  law  constant
1 mole = 6.02 x10^23  atoms
what about 6.02  x10^23 atoms =? moles
cross  multiplication
(1 mole x6.02 x10^23 atoms)/(6.02 x10^23 atoms)=  1 mole  of carbon

question  5
by  use Avogadro law  constant
1 mole =6.02 x10^23 molecules
what  about 4.9 x10^23  moles =?  moles
by   cross  multipication
=( 1mole x 4.9  x10^23 molecules) /6.02 x10^23  molecules = 0.81  moles  ZNCl2
