How far is Mercury from the sun?

Astronomers convert large distances such as these to astronomical units. An astronomical unit (AU) is 93 million miles, which is the average distance from the sun to Earth. In this regard, Mercury's average distance from the sun is 0.387 AU. To put this into perspective, Neptune's average distance from the sun is 30.1 AU. The closest Mercury comes to Earth during its orbit is 48 million miles.

What are some bad things about wind energy?

Wind energy only works when the wind is blowing at a sufficient speed. Energy is hard to store, so other forms of energy need to work in concert with wind to provide consistent reliable power. One advantage for wind compared to solar is that wind power is not based on time of day.\nThe cost to acquire land, install turbines and build other infrastructure is high compared to some other forms of energy. As turbine technology has improved, the costs to install and operate wind farms have come down to a rate that is competitive with other forms of energy. Efficiency is achieved by grouping many wi..

What is the melting temperature of ice?

The temperature at which ice melts depends on pressure. Unlike many other substances, increasing the pressure lowers the melting point of ice. This also means that the lower pressure on the top of a high glacier increases the temperature at which the ice melts.\nSalt is used to lower the temperature at which ice melts, which keeps it from refreezing on sidewalks and streets as well as in hand-cranked ice cream makers. The melting point of the ice decreases as more salt is added until the salt stops dissolving. Salt lowers the temperature at which ice melts on a sidewalk down to about 15.8 F (-..

What are some uses of mercury II iodide?

Mercury (II) iodide is a red powder that has antiseptic properties. It has been used in the veterinary field as a topical antiseptic and as the active component in germicidal soaps and ointments. It has also been used to treat wounds and has had success as a counterirritant.\nDue to the toxic effects mercury can have on the body, animal owners are cautioned to prevent the animal from licking areas where mercury (II) iodide is applied. Cats and dogs in particular should be monitored for side effects because the medication has a higher rate of absorption through the skin in these pets when compa..

What is the primary function of the circulatory system?

Clinton Community College identifies several exchanges between blood and tissue. For instance, blood carries oxygen from the lungs and delivers it all over the body. Blood also picks up waste, carbon dioxide, and brings it to the lungs for removal, states CCC. Blood also transports nutrients such as glucose, as well as hormones, according to the college. In addition, ammonia is picked up from tissues and taken to the liver for disposal. The CCC indicates that many animals maintain constant healthy body temperatures when heat is circulated through the cardiovascular system.

What are some adaptations of the water lily?

The Tree of Life Web Project explains that one of the adaptations of the water lily, the thorns on the bottoms of the leaves, helps to protect it from fish that might consider it a food source. The thorns also help support the leaves. Likewise, the rims on the leaves of the lily protect it from becoming food for birds and insects. The leaves themselves are wide and flat to keep the lily afloat by distributing the weight. The fourth adaptation, the short-lived flower, helps to increase its pollination chances. The flower, which only blooms at night, lets off a unique butterscotch and pineapple ..

What is the function of a capacitor?

Capacitors store electric energy when they are connected to a battery or some other charging circuit. They are commonly placed in electronic components and are used to maintain a power supply while the device is unplugged and without a battery for a short time. The energy within the capacitor prevents the loss of data, with an example being the RAM of a computer.The capacitor contains two metallic plates that are separated by some form of insulation. The plates store the energy until it is needed.There are different types of capacitors:Axial electrolyc: small, low voltage, general purpose capa..

What is the function of the ejaculatory duct?

According to Healthline, there are two ejaculatory ducts on each side of the prostate. These ducts are around 2 centimeters long and are formed when the vas deferens merges with the excretory duct of a seminal vesicle. Healthline explains that ejaculatory ducts travel through the prostate gland and end in the colliculus seminalis of the urethra.\nHealthline describes a condition called ejaculatory duct obstruction, wherein one or both ejaculatory ducts are blocked. This health problem can be acquired either congenitally or pathologically. When there is blockage in these two ducts, the patient ..

Why is an extra day added to February every four years?

The addition of an extra day to the month of February began during the Roman Empire. At that time, the last month in the Roman calendar was February, and the emperor Julius Caesar decreed that the extra day should be added at the end of each fourth year.\nAfter noting that the Roman calendar and the solar calendar still did not properly align over time, Pope Gregory XII introduced the Gregorian calendar in 1582.
