The pressure at the bottom of a full barrel of water is Poriginal . Determine what happens to the pressure when the radius or he

Sholpan [36]

Answer:

a) P' = P_original, b) P ’= P_original + ρ g Δh

Explanation:

The expression for nanometric pressure is

P = ρ g h

where ρ is the density of the liquid and h is the height

a) we change the radius of the barrel, but keeping the same height

as the pressure does not depend on the radius it remains the same

P' = P_original

b) We change the barrel height

h ’≠ h

we substitute in the equation

P ’= ρ g h’

h ’= h + Δh

P ’= ρ g (h + Δh)

P ’= (ρ g h) + ρ g Δh

P ’= P_original + ΔP

In this case, the pressure changes due to the new height,

*if it is higher than the initial one, the pressure increases

*if the height is less than the initial one, the pressure is less

Explain how two dangerous elements can form a compound that is edible

blsea [12.9K]

Two dangerous elements can form a compound that is edible known as "NaCl salt".

<u>Explanation:</u>

Sodium and chlorine are two very dangerous elements. As the reaction between sodium and water is extremely violent and chlorine is a very toxic gas. But combination of these elements result into a harmless product with unique properties like it is edible and dissolves without exploding in water.

In sodium chloride reaction the atoms of sodium interact with chlorine atoms. Sodium will donate an electron (by becoming positively charged) to acceptor chlorine (which become negatively charged) as given in following reaction

$N a+C l_{2} \rightarrow N a C l$

As sodium and chlorine are very keen to achieve noble gas configuration by completing an octet on donating and accepting an electron respectively.

Does the size of the magnetic field change with the size of the magnet?

mestny [16]

Answer:

Not all of the time, it can also depend on the strength of the magnet.

Explanation:

say you have a small very strong magnet, that might work just as well as a large but week magnet.
