Answer:

A. Adding another bulb will make the two of them light a little less brighter since the electrical flow is divided into two making them work.

B. There is a possibility that the flow of electricity maybe little due to the thickness of the wire. There could also be a rise in the temperature of the cell and the bulb.

C. The Bulb will shine brighter because of the extra power or electricity provided! Also, if the voltage is too much, expect the bulb to burn out or sadly, explode.

BTW GOODLUCK!!

The lines in an atomic spectrum indicates the transition of electrons from  higher energy level to the lower energy level. Hence, option d is correct.

The investigation of the electromagnetic radiation that atoms absorb and release is known as atomic spectroscopy. Atomic spectroscopy, specifically the electromagnetic spectrum or mass spectrum, is used to determine the elemental compositions of substances since distinct elements have distinctive spectra.

Depending on the type of spectroscopy being utilized or the atomization source, it can be divided. The primary distinction in the latter instance is between optical and mass spectrometry. Although substantially more difficult, mass spectrometry typically provides significantly higher analytical performance.

Electrons can migrate between orbitals, but doing so requires them to either absorb or emit energy equivalent to the difference in energy levels between the quantized orbitals of their respective atoms.

Answer: the reason why the balance increases is because it is heavier so that's why it increases more

Explanation: the definition for balance is the ability to move or to remain in a position without losing control or falling. : a state in which different things occur in equal or proper amounts or have an equal or proper amount of importance.

Mass is the amount of matter something is made from. Big things are generally more massive than small ones. If you have a lump of iron or copper and take it to different places on Earth (or even the Moon) to measure it's mass, you'll always get the same result.

Weight is a measurement of how much the force of gravity acts on a given amount of mass. The force of gravity varies slightly all over Earth so, while your lump of iron has the same mass, its weight varies: it might weigh a little bit more in Bangladesh than it does in Tibet. What about on the Moon? Gravity is about one sixth the strength on the Moon as it is on Earth. So things weigh only one sixth as much on the Moon as they do on Earth, even though their mass is exactly the same in both places. Why are things heavier on Earth? Essentially because Earth is so much more massive than the Moon. It attracts objects with more force—and that gives them more weight.

The Grand Canyon began its formation about 5 my ago by the erosive action of the Colorado River. Its sedimentary layer composition reflects its history, keeping fossilized living forms that used to inhabit the area.

--------------------

The Grand Canyon formation began approximately 5 million years ago, thanks to the erosive action of the Colorado River.

The strength of the colorado river caudal, together with deglaciation and humidity factors, began to cause an uncontrollable erosion process in these lands that were previously part of the sea bottom.

Originally many strata and sediments accumulated at the bottom of the ocean. With time these extensive areas were exposed when the Rocoses Mountains got formed by the end of the cretaceous (70 million years ago).

Now, by looking at the composing layers, it is possible to understand its formation.

The Grand Canyon is almost entirely composed of sedimentary rock.

It was formed while sediments of sand and mud got deposited in thick layers at the bottom of the ocean and got compacted through the pass of time until becoming a rock.  

Sedimentary rocks have been chronologically accumulating for years, reflecting the geological formation known as superposition.  

According to this sedimentary deposition, we can distinguish the older rocks located in the deepest areas from the younger rocks in more superficial layers.

Each layer keeps fossilized organisms that used to inhabit this area in the past.
