In 1887, Albert A. Michelson and Edward W. Morley conducted an experiment to measure the speed at which the Earth moves through

the ether. Their experiment was so refined that it should have finally detected the luminiferous ether. But it didn't. Repeated trials verified the surprising result that the ether did not exist. How did the failure of the Michelson-Morley experiment change scientific theories of light? A. The Michelson-Morley experiment provided a new theory that fit the data better than the theory of the luminiferous ether did. B. The results of the Michelson-Morley experiment had to be rejected because the theory of the luminiferous ether was so well established. C. The results of the Michelson-Morley experiment did not fit the theory of the luminiferous ether, so the theory had to be rejected. D. The Michelson-Morley experiment proved that the luminiferous ether moved at the exact same speed as the Earth during all seasons of the year.

Answer:

The correct answer is option C. "The results of the Michelson-Morley experiment did not fit the theory of the luminiferous ether, so the theory had to be rejected".

Explanation:

The notorious Michelson-Morley experiment changed the way empty spaces were perceived at their time. Before 1887, the scientific community believed the existence of the luminiferous ether, a substance that supposedly was in empty spaces and allowed electromagnetic waves propagation. The results of the Michelson-Morley experiment did not fit the theory of the luminiferous ether, and the experiment was so refined that the theory had to be rejected.

How are the carbon, oxygen, and nitrogen cycles vital to sustaining life on Earth?. a.. Carbon, oxygen, and nitrogen are vital c
kumpel [21]

The correct answer is (D)


All the above are reasons the carbon , oxygen, and nitrogen cycles are vital to life on earth.


The explanation:


because :


1) Carbon, oxygen, and nitrogen are vital components of life on Earth.


2) The carbon, oxygen, and nitrogen cycles allow vital elements to return to usable form by organisms.


3)The carbon, oxygen, and nitrogen cycles are an important interface between biotic and abiotic factors


4) They are all biogeochemical cycles.


5) They all involve an interaction between living and nonliving elements.

6)They are all part of the Earth system.

When a mercury-202 nucleus is bombarded with a neutron, a proton is ejected. What element is formed?
Galina-37 [17]

That will make a gold-202 nucleus.

<h3>Explanation</h3>

Refer to a periodic table. The atomic number of mercury Hg is 80.

Step One: Bombard the \displaystyle ^{202}_{\phantom{2}80}\text{Hg} with a neutron ^{1}_{0}n. The neutron will add 1 to the mass number 202 of ^{202}_{\phantom{2}80}\text{Hg}. However, the atomic number will stay the same.

  • New mass number: 202 + 1 = 203.
  • Atomic number is still 80.

^{202}_{\phantom{2}80}\text{Hg} + ^{1}_{0}n \to ^{203}_{\phantom{2}80}\text{Hg}.

Double check the equation:

  • Sum of mass number on the left-hand side = 202 + 1 = 203 = Sum of mass number on the right-hand side.
  • Sum of atomic number on the left-hand side = 80 = Sum of atomic number on the right-hand side.

Step Two: The ^{203}_{\phantom{2}80}\text{Hg} nucleus loses a proton ^{1}_{1}p. Both the mass number 203 and the atomic number will decrease by 1.

  • New mass number: 203 - 1 = 202.
  • New atomic number: 80 - 1 = 79.

Refer to a periodic table. What's the element with atomic number 79? Gold Au.

^{203}_{\phantom{2}80}\text{Hg} \to ^{202}_{\phantom{2}79}\text{Au} + ^{1}_{1}p.

Double check the equation:

  • Sum of mass number on the left-hand side = 203 = 202 + 1 = Sum of mass number on the right-hand side.
  • Sum of atomic number on the left-hand side = 80 = 79 + 1 = Sum of atomic number on the right-hand side.

A gold-202 nucleus is formed.
