Radiant heating can direct warm air where it is needed and it is not an advantage.

Answer: Option B

<u>Explanation:</u>

Radiant heating is the process in which the heat is supplied directly to the floor and to the object. It uses infrared radiation which is a form of electromagnetic waves.

They are capable of heating the floor uniformly. Without any need for corrections and they are easy to install also. Their disadvantage is that they are capable of sucking warm air.

The total charge that passes through an electrolytic cell is given by the product of?
Sergeu [11.5K]

The total charge that passes through an electrolytic cell is given by the product of current and time.

An electrolytic cell is an electrochemical cell that utilizes an external source of electrical energy (voltage applied between two electrodes) to drive a chemical reaction that would not otherwise occur. This is in contrast to a galvanic cell, which itself is a source of electrical energy and the foundation of a battery.

The net reaction taking place in a galvanic cell is a spontaneous reaction, i.e. the Gibbs free energy remains negative, while the net reaction taking place in an electrolytic cell is the reverse of this spontaneous reaction, i.e. the Gibbs free energy is positive.

An electrolytic cell has three components: an electrolyte and two electrodes (a cathode and an anode). The electrolyte is usually a solution of water or other solvents in which ions are dissolved.

Molten salts such as sodium chloride can also function as electrolytes. When driven by an external voltage applied to the electrodes, the ions in the electrolyte are attracted to an electrode with the opposite charge, where charge-transferring (also called faradaic or redox) reactions can take place.

Only with an external electrical potential (i.e., voltage) of correct polarity and sufficient magnitude can an electrolytic cell decompose a normally stable, or inert chemical compound in the solution. The electrical energy provided can produce a chemical reaction which would not otherwise occur spontaneously.

RoseWind [281]

Answer:

The correct option is c. 75 for this question

Explanation:

The correct option is c. 75 for this question:

Let's see how.

Continuity Equation is given as:

AcVc = AaVa

Where,

Aa = Area of Aorta

Ac = Area of the capillary

Va = Fluid speed in Aorta

Vc = Fluid speed in Capillary

So,

Assuming the fluid is the ideal one/

\pi/4 Dc^{2} Vc= \pi/4 Da^{2} Va

Dc^{2} Vc= Da^{2} Va

Dc = Da x \sqrt{\frac{Va}{Vc} }

Dc = 2.5 cm x \sqrt{\frac{60 cm}{0.07 cm } }

Dc = 73.192 cm

Dc = 75 approximately

Hence, the diameter of the capillary = 75 cm approximately
