If we move a conductor through a magnetic field, what will we create?

Induced EMF becomes zero when the movement of the conductor stops. The induced voltage is observed to be larger if the magnetic field, conductor motion and the conductor are perpendicular to each other. The copper wire, a conductor, contains free electrons. The movement of the conductor allows these electrons, to arrive at one side of it, leaving the other side positively charged. Hence, a voltage is developed by the separation of charges.

What is the difference between NADH and NADPH?

NAD, or nicotinamide adenine dinucleotide, is the basic coenzyme or molecule powering many cellular reactions. In cellular respiration, or the process of producing energy in the cells, this compound combines with two hydrogen atoms. Building up molecules in this way is called anabolism. The compound takes one hydrogen atom and the electron from the other hydrogen atom to turn into high-energy NADH. NADH then travels with the extra electrons and drops them off, releasing energy in a process called catabolism, when a molecule breaks down to produce energy.\nNADP, or nicotinamide adenine dinucleo..

What is the conversion formula for cubic feet to gallons?

A foot is an imperial measure of length in one dimension. By using area formulas for various shapes, area can be calculated in feet squared. Area is a two dimensional measurement, while volume is a three dimensional measurement. By integrating depth or height into area equations to derive volume equations, a volume result can be calculated in cubic feet. This can then be converted to gallons.

Does Pluto have gravity?

Pluto has a surface gravity approximately 1/12th of Earth's, according to the California Institute of Technology. In other words, an object that weighs 50 pounds on Earth would weigh 4 pounds on Pluto. It's important to understand that weight isn't the same as mass. Mass is a constant, whereas weight is a function of gravity. Objects with more mass usually have more gravity as a result.

What are the components of air?

If air is not completely dry, water vapor may be up to 5 percent of its composition. The presence of water does not change the relative proportions of other gases.\nDifferent layers of the atmosphere contain differing air compositions. For example, water vapor is mostly contained in the lowest layers of air, while about 90 percent of the Earth's ozone is contained within the stratosphere. The very light elements helium and hydrogen are mostly found in the outer layer, the exosphere.

What is the oxidation number of manganese in MnO2?

As the guidelines for nonmetals indicate, oxygen always has an oxidation number of -2 when paired with metals such as manganese. This requires manganese to take a charge of +4, so the MnO2 compound has a neutral total charge.\nThe manganese ion also exhibits other oxidation numbers, such as +2 and +7. For example, in KMnO4, the potassium ion has a charge of +1 and each of the oxygen ions has a charge of -2, which causes the manganese ion to take a charge of +7.

What is 6O2 in Chemistry?

Oxygen is most stable when it is in groups of two atoms, hence O2 is oxygen at its most stable. With regard to mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. 6O2 is commonly seen in biology, as it is found in many equations of life. One example is 6CO2 + 6H2O + energy = C6H12O6 + 6O2. This is the equation for photosynthesis.

How hot is the Earth's crust?

The Earth's crust is the outermost layer of the planet. Essentially, the ground can be considered the Earth's crust; just a thin layer of rock that only makes up one percent of Earth's mass. According to the Universe Today, the thickest part of the Earth's crust can be found in South Africa, where there is a gold mine that measures almost 4 km deep.

What is the formula for converting inches to feet?

Different units of measurement are used in everyday and scientific life. These units of measurement may also vary in different locales. The English or imperial system, with inches and feet as primary linear measurements, is preferred in the United States. Most of the rest of the world relies on the metric system of measurements, which includes meters and centimeters. The scientific community also primarily uses the metric system.

What is alpha-lipoic acid?

Alpha-lipoic acid is believed to prevent cellular damage in the body. It also has the ability to restore vitamin C and vitamin E levels in the body. The antioxidant has also been linked to improving the function of neurons in the bodies of diabetic patients. The antioxidant can protect cells and repair cellular damage that has been caused by free radicals in the body.
