Explanation

To find the angle in radians per second, first convert the rpm (revolutions per minute) to radians per second.

3000 rpm =  3000/60 ​revolutions per second =  50 revolutions per second.

Each revolution is  2π radians.

So, 

50×2π=100π radians per second.

Explanation

Torque and candela are indeed unrelated physical quantities.

Torque is a measure of the rotational force applied to an object

Measured in newton-meters (Nm) or foot-pounds (ft-lb)

While

Candela is a unit of luminous intensity

Measuring the brightness of light emitted in a particular direction

Explanation

The substance used to absorb carbon dioxide gas in combustion analysis is 50% KOH (potassium hydroxide)

50% KOH (potassium hydroxide):

Potassium hydroxide is used to absorb CO (_2) because it reacts with CO (_2) to form potassium carbonate (K(_2 )CO (_3) and potassium bicarbonate (KHCO (_3)).

This makes it an effective absorbent for CO(_2) in combustion analysis.

[ 2KOH + CO_2 rightarrow K_2CO_3 + H_2O ]

 [ KOH + CO_2 rightarrow KHCO_3 ]

Explanation

Gallstones, mainly cholesterol gallstone formation, result from several physiological events such as:

• hepatic secretion of bile saturated with cholesterol
• nucleation of cholesterol monohydrate crystals in the gall bladder
• impaired emptying of gall bladder contents.

Explanation

Cement does typically contain a small percentage of gypsum.

Gypsum (calcium sulfate dihydrate, (CaSO4 ⋅ 2H2O) is added to cement primarily to regulate the setting time.

The percentage of gypsum in cement is usually around 2-5%.

It prevents the cement from setting too quickly by controlling the rate at which the cement hydrates and hardens. 

Explanation

The molality (m) of a solution is the moles of solute divided by the kilograms of solvent. A solution that contains 1.0mol of NaCl dissolved into 1.0kg of water is a "one-molal" solution of sodium chloride.

The symbol for molality is a lower-case m written in italics.

Explanation

Ventilation: the process of bringing oxygenated water or air into contact with a gas-exchange surface.

Explanation

A motor neuron carries impulses from the CNS to muscles, causing them to contract.
