Explanation:

We know that rate of flow through a cross section :

v1 \times a1 = v2 \times a2

5 m/s * 1.76cm^2 = v2 * 7.06cm^2

v2 = 1.24 \: m {s}^{ - 1}

What happens to the volume the gas occupies when the pressure on a gas increases?
taurus [48]
Each time they collide with the walls they exert a force on them. More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases. This shows that the pressure of a gas is inversely proportional to its volume.

Answer:

2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)

Explanation:

The reaction is a neutralization reaction since an acid, aqeous H2SO4 reacts completely with an appropriate amount of alkali, aqueous KOH to produce salt, aqueous K2SO4 and liquid water, H2O only.

2KOH(aq) + H2SO4(aq) ⇒ K2SO4(aq) + 2H2O(l)

Alkali + Acid → Salt + Water.

During this reaction, 2 moles of KOH neutralize 1 mole of H2SO4 to yield 1 mole of K2SO4 and 2 moles of H2O.

What is tension?

Tension occurs due to the direction of pull on the object and along the length of the given rope.

It's S.I. unit is Newton

Tension formula can be represented as

T = mg + ma

T = 200 (9.8 + 1.3 m/s²)

T = 200 (12.74)

T = 2,548
