c. Sodium and potassium

<h3>What is called perspiration?</h3>

Perspiration, water given off by the intact skin, either as vapor by simple evaporation from the epidermis or as sweat, a form of cooling in which liquid actively secreted from sweat glands evaporates from the body surface.

When our body is sweating sodium and potassium is lost from the body along with water.

In order to maintain the integrity of the cells in the body ,Sodium and potassium are very important.

Sweat is also known as perspiration.

So,

By maintaining the proper cell functioning and cell vitality optimum level of sodium and potassium should be maintained in the body.

When heating water, during what temperature range will the temperature cease to change for some time?

Morgarella [4.7K]

Answer: Option (B) is the correct answer.

Explanation:

As we know that the temperature when the vapor pressure of liquid becomes equal to the atmospheric pressure surrounding the liquid. And, during this temperature liquid state of substance changes into vapor state.

But during this process of change in state of substance the temperature will cease to change for some time because unless and until all the liquid molecules do not convert into vapor state the temperature will not rise or change.

As the boiling point of water is $100^{o}C$ so the temperature ceases to change from $98^{o}C$ to $102^{o}C$ .

Therefore, we can conclude that when heating water, during $98^{o}C$ to $102^{o}C$ temperature range the temperature will cease to change for some time.

Andrea, a 61.5 kg sprinter, starts a race with an acceleration of 3.700 m/s2. If she accelerates at that rate for 12.00 m and th

morpeh [17]

Answer:

The total time it will take her to complete the race is 13.17 s

Explanation:

Given;

mass of the sprinter, m = 61.5 kg

acceleration of the sprinter, a = 3.7 m/s²

first distance covered, d₁ = 12 m

Determine her velocity for the first 12 m;

v² = u² + 2as

v² = 0 + (2 x 3.7 x 12)

v² = 88.8

v = √88.8

v = 9.42 m/s

Determine her time for the first 12 m;

v = u + at

9.42 = 0 + 3.7t₁

9.42 = 3.7t₁

t₁ = 9.42 / 3.7

t₁ = 2.55 s

Determine the time it will take her to complete the last 100 m at a constant velocity of 9.42 m/s

s = vt₂ + ¹/₂at₂²

s = vt₂ + ¹/₂(0)t₂²

s = vt₂

100 = 9.42t₂

t₂ = 100 / 9.42

t₂ = 10.62 s

The total time it will take her to complete the race = 2.55 s + 10.62 s

= 13.17 s

A 15-V battery is connected to three capacitors in series. The capacitors have the following capacitances: 4.3 µF, 12.6 µF, and

kotykmax [81]

Answer:

1.394 V

Explanation:

When a capacitor is connected in series, The sum of a capacitance is given as

1/Ct = 1/C1 + 1/C2 + 1/C3 ............................... Equation 1

Where Ct = Value of the combined capacitor, C1 = first capacitance, C2 = Second capacitance, C3 = Third capacitance.

Given: C1 = 4.3 µF, C2 = 12.6 µF, C3 = 31.2 µF

Substitute into equation 1

1/Ct = 1/4.3 + 1/12.6 + 1/31.2

1/Ct = 0.233 + 0.0794 + 0.0321

1/Ct = 0.3445

Ct = 1/0.3445

Ct = 2.9 µF.

But

Q = CtV .................................. Equation 2

Where

Q = Amount of charge, V = voltage, C = total capacitance

Given: V = 15 V, Ct = 2.9 µF

Substitute into equation 1

Q = 15(v) ×2.9(µF)

Q = 43.5 µC

The voltage across the 31.2 µF is

V₃ = Q/31.2 µF......................... equation 3

Where V₃ = The voltage across the 31.2 µF capacitor.

Note: When capacitors are connected in series, the same quantity of charge flows through them.

V₃ = 43.5 (µC)/31.2 (µF)

V₃ = 1.394 V.

Hence the voltage across the 31.2 µF = 1.394 V
