A car accelerates uniformly from rest to a final speed of 19 m/s in 10. seconds. How far does it travel during this period of ac
lions [1.4K]

Answer:

x = 95 [m]

Explanation:

To solve this problem we must use the following equation of kinematics.

v_{f} =v_{o} +a*t

where:

Vf = final velocity = 19 [m/s]

Vo = initial velocity = 0 (starts from the rest)

a = acceleration [m/s²]

t = time = 10 [s]

Now we can find the acceleration

19 = 0 *a*(10)

a = 1.9 [m/s]

With the second equation we can find the distance:

v_{f} ^{2} =v_{o} ^{2} +(2*a*x)

where:

x = distance [m]

(19)² = (0)² + (2*1.9*x)

3.8*x = 361

x = 95 [m]

The hydronium ion concentration of your gastric fluid is 1.0 x 10^-2. you drink a tablespoon of milk of magnesia, which raises t
slamgirl [31]

Answer:

[OH⁻] = 1 × 10⁻¹¹ mol/dm³

Explanation:

Since the hydronium ion concentration of the gastric fluid is [H₃O]⁺ = 1.0 × 10⁻².

The pH at this point is pH = -log₁₀[H₃O]⁺ = -log₁₀[1.0 × 10⁻²] = 2

When milk of magnesia is added, the pH increases by one unit, so the new pH is 1 + 2 = 3

Since pH + pOH = 14, then pOH = 14 - pH = 14 - 3 = 11

The hydroxide ion concentration of the fluid is gotten from

pOH = -log₁₀[OH⁻]

11 = -log₁₀[OH⁻]

-11 = log₁₀[OH⁻]

taking antilog

[OH⁻] = 1 × 10⁻¹¹ mol/dm³
