If your vehicle sinks in water, which window should you kick out when the pressure equalizes?

1 answer:

6 0

<span>If your vehicle sinks in water and assuming that you are the driver, you should kick out the driver's window when the pressure equalizes.

You should't waste your time trying to reach the rear window and you shouldn't break the front window. Therefore, just break the one nearest to you which is the driver's window in this case.</span>

If an equivalent (eq) is defined as a mole of charge, what is the concentration of ca2 in blood plasma in eq if its concentratio

Andrei [34K]

The concentration of ca2 in blood plasma is comparable if it is 0.0080, according to the supplied statement.

<h3>How do you quantify concentration?</h3>

Subtract the solute's mass from the total volume of the mixture. Calculate C = m/V, where m is the solute's mass and V seems to be the total volume of such solution. Divide the figures you found for mass and volume to find approximate concentration for your solution.

<h3>What is the definition of concentration in the solution?</h3>

A solution's concentration is a measure of how much solute has been dissolved in a specific amount of the solvent or solution. A concentrated solution contains a significant amount or dissolved solute. A dilute solution is one with a little amount of dissolved solute.

<h3>According to the given data:</h3>

The equivalent weight of detail is the mass that combines with someone or displaces 1.008 grams of molecular hydrogen, or eight.

35.5 grams of chlorine or 0 grams of oxygen.

Those figures are the atomic weight divided by that of the normal valence, which is sixteen in the case of oxygen.

One Ca2+ ion has a charge of +2.Calcium ion concentration:

= 0.0040M ⇒ Ca 2+ Concentration in blood plasma

= 0.0040 × 2⇒ 0.0080 equivalent Ca2

What name is given to a process where a substance melts under pressure?

Digiron [165]

Answer:

Melting

Explanation:

The process of a solid becoming a liquid is called melting. (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance.

To understand the formula for power radiated in the form of electromagnetic energy by an object at nonzero temperature. every ob

lbvjy [14]

As per Stefan - Boltzmann law we know that

1. Power radiated in the form of electromagnetic energy by an object at nonzero temperature.

2. Every object at absolute (kelvin) temperature t will radiate electromagnetic waves.

3. This radiation is typically in the infrared for objects at room temperature, with some visible light emitted for objects heated above 1000 k.

4. The formula governing the rate of energy radiation from a surface is given by $p=eσat^4$ ,

where p is the thermal power (also known as the heat current h).

Thermal radiation in visible light can be seen on hot metalwork. Its emission in the infrared is invisible to the human eye. Infrared cameras are capable of capturing this infrared emission.

Thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. Particle motion results in charge-acceleration or dipole oscillation which produce electromagnetic radiation.

Examples of thermal radiation include the visible light and infrared light emitted by an incandescent light bulb, the infrared radiation emitted by animals that is detectable with an infrared camera, and the cosmic microwave background radiation. Thermal radiation is different from thermal convection and thermal conduction—a person near a raging bonfire feels radiant heating from the fire, even if the surrounding air is very cold.

Sunlight is part of thermal radiation generated by the hot plasma of the Sun. The Earth also emits thermal radiation, but at a much lower intensity and different spectral distribution. The Earth's absorption of solar radiation, followed by its outgoing thermal radiation, are the two most important processes that determine the temperature and climate of the Earth in most climate models.

So the correct answer which is applicable here will be

This formula applies to any object of total surface area a, kelvin temperature t, and emissivity e

here

$\sigma[\tex] = stefan boltzmann constant = [tex]5.67 * 10^{-8}$
