Engineering

An electron jumps from the ground state to an excited state when it absorbs energy, typically in the form of a photon. This causes the electron to move to a higher energy level, creating an excited state. When the electron later falls back to the ground state, it releases the absorbed energy in the form of a photon.

Lactic acid belongs to the carboxylic acid functional group. This functional group consists of a carbonyl group (C=O) and a hydroxyl group (OH) attached to the same carbon atom.

After studying biochemistry at college, you can work in various fields such as pharmaceuticals, biotechnology, healthcare, research, food and beverage industries, environmental sector, or pursuing further education in fields like medicine, pharmacy, or bioinformatics.

During ductile deformation, a material undergoes plastic deformation, meaning it permanently changes shape without breaking. This results in the material stretching and elongating before eventually yielding and forming necks or thin regions. The material exhibits a higher degree of deformation before fracture compared to brittle materials.

Snow socks use friction to provide the grip. Dry snow and ice sticks to fabric and the Socks are made from a technical fabric which sticks to the snow. The specially developed textile also "wicks away" any water that's found between the ground and the tyre, (generated e.g. by the warmth of the sun, or wheel spin), thereby maximising the friction grip.

The pressure at sea level on Earth is about 14.7 pounds per square inch (psi), while the pressure in outer space is close to zero psi. This means that there is a pressure difference of 14.7 psi between sea level on Earth and outer space.

The correct value for the specific heat of water is 4.1868 joules per gram per degree Celsius. This means that it takes 4.1868 joules of energy to raise the temperature of 1 gram of water by 1 degree Celsius.

The Human LD50 information we currently have come the scientist! obviously hahhahahaha.... Idk actually..if you know please answer as soon as possible. Thank you soo much for everything, and reading this ...pointless junk..ahha!

Tungsten is one of the hardest metals to break due to its high tensile strength and durability. It is commonly used in industrial and military applications that require materials with exceptional hardness and resistance to wear and tear.

An inertia governor is a device used to regulate the speed of an engine by controlling the fuel or air flow. It works by adjusting the position of the throttle or fuel metering valve in response to changes in engine speed. As the engine speed increases or decreases, the governor uses centrifugal force to actuate the throttle, maintaining a steady speed.

Stripping steam aids in separation in the column by "stripping' lighter components to higher trays in the column. While the crude is heated to a temperature where the pure components would normally go up, in crude oil the lighter components are often entrained in the heavier ones and the separation is not ideal. In actual practice stripping steam rates affect the flash points of the products as well as the concentration of hydrogen sulfide (H2S) in the products. The stripping steam added to the bottom of the column also affects the amount of overflash in the flash zone.

Atomized liquid refers to the process of breaking a liquid into very small droplets or particles through atomization. Atomization can be achieved through various methods such as spraying, nebulizing, or using specialized equipment like atomizers. This process is commonly used in industries such as pharmaceuticals, agriculture, and combustion for applications like spraying pesticides, creating inhalable medications, or improving fuel-air mixing.

A water separator is used to remove bulk water from a gas stream, while a moisture separator is used to remove fine water droplets or mist from a gas stream. Water separators are typically used in larger industrial applications, while moisture separators are used in processes where precise control of moisture content is important, such as in compressed air systems.

Basalt is considered to have low to moderate permeability, meaning it allows some water to flow through it, but at a slower rate compared to more porous rocks. This can vary depending on factors such as the porosity and fractures within the basalt.

"Liquid quantity per hour" is a flow rate. It can be (any unit of volume) divided by (any unit of time).

Some widely-used candidates are:

-- cubic feet per minute

-- gallons per minute

-- liters per second

etc.

Oil has the highest specific gravity. Water has the second.

The radiation resistance of a folded dipole antenna is typically higher than that of a simple dipole antenna, approximately 300 ohms compared to 73 ohms. This increase in radiation resistance helps improve the efficiency and performance of the antenna. The folded design allows for a more compact structure while maintaining good radiation characteristics.

The angle of repose for steel chips can vary depending on factors such as the size, shape, and surface characteristics of the chips. Generally, the angle of repose for steel chips is between 30 to 45 degrees. Experimental testing may be needed to determine the specific angle of repose for a particular type of steel chip.

The formula for quantity can vary depending on the context. In general, quantity refers to the amount or number of something. It can be calculated using different formulas depending on the specific situation, such as the quantity of a substance in chemistry, the quantity of goods sold in business, or the quantity of items in a set.

Dew point temperature is the temperature at which air becomes saturated with moisture and dew forms. As pressure increases, the air can hold more moisture before reaching saturation, leading to a higher dew point temperature. Conversely, a decrease in pressure lowers the air's capacity to hold moisture, resulting in a lower dew point temperature.

A water bath circuit typically consists of a heating element (e.g., a heating coil), temperature sensor (e.g., a thermocouple), thermostat, and power source. The water bath is used in laboratories to provide a consistent temperature environment for experiments requiring gentle heating or cooling, such as incubation, crystallization, and maintaining samples at a specific temperature for extended periods.

You just need hydrochloric acid. "The Works" bomb contains HCL, and when you add aluminum to it, hydrogen gas is released which causes the bomb. If you have hydrochloric acid on hand, you can dilute it to about 16 percent and use it in place of the works bomb.

But be careful, as the explosion can send send pieces of the bottle and acid spewing everywhere. And the explosion sound is like a gunshot.

Consider a case , where an earth switch is closed and You are trying to close the Line breaker , in this situation , the relay trips the breaker instantaneously without any conditions or any time delay . This is called Switc On To Fault .

There is one periodic table that is universally recognized and used by scientists worldwide. It is periodically updated to reflect new elements or discoveries. The most recent version is the 7th period which showcases all known elements up to that point.

The "L" suffix signifies this is the low carbon variant on this grade. See the composition limits listed in the material standard ASME Section II Part C for stainless steels in SFA 5.4 and 5.9

The low carbon grade is often used to protect from intergranular corrosion.
