Your friend says that he heard about some rocks that would glow when they were put under a certain kind of light. Can light cause rocks to glow?.
Answer:
Yes. Rocks can take in energy from the light, causing them to glow.
Explanation:
No. Light cannot alter physical objects like rocks because it is not a physical substance.
What is Flourescence ?Flourescence is the process by which the energy from a black light or UV light interacts with the chemicals in a mineral to produce a glowing effect.
Sunlight's ultraviolet rays can cause paper and cloth to lose their colour. When ultraviolet light waves are present, the compounds in coloured dyes can degrade. Sunburns can also be brought on by ultraviolet rays.
It is possible for minerals to reflect light. They become apparent to the human eye as a result. "Fluorescence" is a fascinating physical characteristic of several minerals. These minerals can briefly absorb a tiny bit of light and then release a tiny amount of light of a different wavelength.
The mineral temporarily changes colour in the observer's eye due to this shift in wavelength.
When fluorescent minerals are exposed to UV light—which humans cannot see—in the dark and then emit visible light, the colour change is particularly impressive. This phenomena is seen in the image above.

A six-sided number cube is rolled 300 times. The results are 120 even numbers and 180 odd numbers.
How does the relative frequency of rolling an even number compare to the theoretical probability?
Select from the drop-down menus to correctly complete the statements.
The relative frequency of rolling an even number is
Choose... 1. A equal to B Greater than C Less than
the theoretical probability. The theoretical probability is
Choose...2. A 0.4 B 0.5 C 0.6
and the relative frequency is
Choose... 3. A 40% B 50% C 60%
Answer:
Expectation of an event is the total number of experiments times the peobability of occurance of that event.
For example, if a die is thrown 6 times then the expected number of times that the number is 2 is 1/6∗6=1
Explanation:
The relative frequency of rolling an even number is C)Less than the theoretical probability. The theoretical probability is B)0.5 and the relative frequency is A)40%.
The theoretical probability P is P = 3/ 6
=1/2
=0.5
The relative frequency F is F = 120 / 300 * 100 %
= 2 / 5 * 100 %
= 40 %
Therefore, 2 / 5 < 1 / 2 the relative frequency of rolling an even number is less than the theoretical probability.

Water near the equator is warmer than water at the poles. Which sentence explains why?
A) deep sea vents pumps steam into oceans unevenly
B) upwelling spew warm water toward the equator
C) dense, salty water tends to hold more heat
D) the sun heats earth and it ocean unevenly
*Environmental science*
Hi there!
You will have already be known that the sun's rays are closest to the equatorial regions than the polar regions. So the stronger heat rays reach the equator first, heating it's water faster. Within the span of time when the rays reach the polar areas (poles), the sun rays become slanted, leading it into the ocean waters.
Also, the sharpness or intensity of the rays gets weakened, thereby heating the water of polar regions less.
Using this fact, we can say that the rays falling near the equator heats the water more than the rays heating the water at poles.
Hence, we can say that D) The sun heats earth and it ocean unevenly will be your answer.
Thank you !
Where is this beautiful beach known for its pink sand?.
At which position is the southern hemisphere experiencing spring?
The image includes the position and tilt of Earth in its orbit around the sun. Earth has tilted away from the sun in position A. In position B, the sun shines evenly on Earth from pole to pole. Earth is tilted toward the sun in position C. In position D, the sun shines evenly on Earth from pole to pole.
The position in which the Southern Hemisphere is experiencing Spring is:
B. Earth is tilted toward the sun in positionThis refers to the half of the earth which is to the South of the Equator and in which the five continents can be found.

What is human system?The physical component of the human organism, the human body is made up of extracellular and live cells and is divided into many tissues, organs, and systems.
Of course, humans are animals; more specifically, they are members of the order Primates, which belongs to the phylum Chordata's subphylum Vertebrata.
The human animal, like all chordates, has a bilaterally symmetrical body that, at some time during its development, developed gill slits near the throat and a hollow dorsal nerve cord.
The first two of these characteristics are only present in the human embryo; the pharyngeal gill slits are completely eliminated, and the notochord is replaced by the vertebral column. In humans, the spinal cord is the dorsal nerve cord.
