Answer: The charge on the plates are 88.4 picafarad

Explanation:The equation used in measuring charge in a plate is given as:

C=Q/V =E A/D

Where E= dielectric content

A= Area of plates

d= distance between plates

Using dielectric constant for Air=8.84×10-12F/m

A=100cm2=0.01m2

d=10mm=0.001m

C= 8.84×10-12×0.01/0.001

C= 88.4 picafarad

If the concentration of a KCl solution is 16.0% (m/v), then the mass of KCl in 26.0 mL of solution is ________.
melomori [17]

Answer:

The correct answer is 4.16 grams.

Explanation:

Based on the given information, the concentration of KCl solution is 16 % m/v, which means that 100 ml of the solution will contain 16 grams of KCl.

The molarity of the solution can be determined by using the formula,

M = weight/molecular mass × 1000/Volume

The molecular mass of KCl is 74.6 grams per mole.

M = 16/74.6 × 1000/100

M = 16/74.6

M = 2.14 M

Now the weight of KCl present in the solution of 26 ml will be,

2.14 = Wt./74.6 × 1000 /26

Wt. = 4.16 grams

What is most likely the ph of a solution containing many hydroxide ions (oh-) and few hydrogen ions (h )?
SIZIF [17.4K]
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>

The Coriolis effect influences _____. neither wind speed nor wind direction wind speed both wind speed and wind direction wind d
Alona [7]

Answer: The correct answer is "wind direction".

Explanation:

Coriolis effect: This is an apparent deflection of moving air or water caused by the rotation of the earth.

Currents are created by wind. Their directions are determined by Coriolis effect.

Currents are created by wind. The earth is in constant motion. It describes the rotation of the earth which steers winds and the surface current. The ocean surface currents are deflected by Coriolis effect.

The direction of the wind blows from north and south towards equator.

Therefore, the Coriolis effect influences wind direction.
