Plane mirrors are used in periscopes to enable viewing around obstacles, in optical instruments like microscopes and telescopes to direct and reflect light, and in security systems to monitor areas without being detected. They are also used in architecture and interior design to enhance lighting and create an illusion of more space.

No. All atoms, except the most abundant isotope of hydrogen, can be divided into the subatomic particles protons, neutrons, and electrons. The most abundant hydrogen isotope does not have neutrons.

Soda is thicker than water due to the presence of dissolved sugars and carbon dioxide gas. These additives increase the viscosity of the liquid, making it feel thicker when compared to plain water.

The southern cross is a well known star configuration which can be seen from the southern hemisphere.

The cross is used to navigate because it's angle is esilly identifiable by many.

There are two bright stars just off from each other near the southern cross which are called the pointers. Theese are used to line up with the cross and determine the angle/direction.

A new day begins at 12:00:01 AM. What would actually be one second after midnight, or 00:00:01 military time.

Yes, when the northern hemisphere is tilted towards the sun, it is summer in that hemisphere. This tilt causes the area to receive more direct sunlight, resulting in longer days and warmer temperatures.

The first calendar month on the Western calendar is January.

That would be a very difficult question to answer with country's such as the USA Russia France and England selling as many as they can every day and covering these sales under various official secrets acts.

Black is the presense of all colors blended together. Rainbows are visible light waves, and are are the only electromagnetic waves we can see. Each color has a different wavelength. Red has the longest wave length and violet has the shortest wave length.

A refracting telescope collects light data, which is then focused and magnified by the curved lenses or mirrors inside the telescope. This light data allows astronomers to observe distant objects such as stars, planets, and galaxies.

St. Agnes was not canonized. She was proclaimed a saint by early
Christians because of her martyrdom. The canonization process did not
come into existence until the 12th century. In the primitive Church,
martyrs were immediately recognized as witnessing to the perfection of
Christian life on earth, having shown the ultimate proof of their love for
Christ by the offering of their lives. By the sacrifice of their lives
for Christ, they attained Heaven in eternal glory and were indissolubly
united to the Lord, the Head of the Mystical Body.

They are important, because it is one of the very first things, before airplanes that can allow you to fly in the sky! It also was the oldest successful human-carrying flight technology and is a subset of balloon aircraft ... Invented by the Montgolfier brothers in 1783.....

A parameter that indicates the size of the human population is increasing is the population growth rate, which is calculated as the difference between the number of births and deaths in a specific time period. Additionally, increasing fertility rates and declining mortality rates can also indicate population growth.

Insects have a wide range of diets depending on the species. Some insects are herbivores and feed on plants, some are carnivores and feed on other insects, while others are omnivores and consume a variety of food such as plants, other insects, or decaying matter.

Theodosius of Bithynia did not invent the first sundial. The sundial is believed to have been invented by the ancient Egyptians or Babylonians around 1500 BC. Theodosius of Bithynia was a Greek astronomer and mathematician known for his work on the geometry of the sphere.

The eye can take around 5-10 minutes to fully adjust from darkness to light. During this time, the pupils will constrict to reduce the amount of light entering the eye, allowing the photoreceptor cells to gradually adapt to the increased light levels.

Yes, the different levels of organization in a multicellular organism are an adaptation as they allow for specialization of functions and efficient division of labor among cells. This organization enables the organism to perform more complex processes and respond effectively to environmental challenges.

1 gram is in the metric system. do you mean 1ounce?

yes,

there is an astronaut helmet.

that describes her well.

Molten zinc or gallium will turn cold when you put a penny in it because they have a lower melting point than the metal in the penny, causing the penny to rapidly transfer its heat to the liquid metal and cool down.

The climate of the veld is highly variable, but its general pattern is mild winters from May to September and hot or very hot summers from November to March, with moderate or considerable variations in daily temperatures and abundant sunshine. Precipitation mostly occurs in the summer months in the form of high-energy thunderstorms.

Over most of the South African Highveld, the average annual rainfall is between 15 and 30 inches (380 and 760 mm), decreasing to about 10 inches (250 mm) near the western border and increasing to nearly 40 inches (1,000 mm) in some parts of the Lesotho Highlands; the South African Lowveld generally receives more precipitation than the Highveld. Temperature is closely related to elevation. In general, the mean July (winter) temperatures range between 45 °F (7 °C) in the Lesotho Highlands and 60 °F (16 °C) in the Lowveld. January (summer) temperatures range between 65 °F (18 °C) and 80 °F (27 °C).

In Zimbabwe the precipitation averages around 30 to 35 inches (760 to 900 mm) on the Highveld, dropping to less than 15 inches in the lowest areas of the Lowveld. Temperatures are slightly higher than in South Africa.

Over the entire veld, seasonal and annual average rainfall variations of up to 40 percent are common. Damaging drought afflicts at least half the area about once every three or four years. Everywhere the average number of hours of annual sunshine varies from 60 to 80 percent of the total amount possible.

So far there is no sign of that happening anytime soon.

The visible surface of the Sun has a temperature of 5,700°K which is approximately 9,800°F or 5,427°C.

A round piece of plate glass is heated and slumped over a curved steel form then silvered on the convex side. Better ones were made by grinding and polishing a convex surface to one side of flat window glass then silvered on the curved side.
