Most body water intake is from drinking, whereas most body water lost is via ; urine.
Where is most of the water of the body found ?
Most body water is found within the extracellular fluid. the 2 major forces that result in the movement of water are fluid pressure and osmotic pressure. In ECF , the main cation is potassium, and therefore the major anions are chloride and bicarbonate.
How does water get distributed within the body?
The water we drink is absorbed by the intestines, and circulated throughout the body within the form of body fluids such as blood. These perform various functions that keep us alive. They deliver oxygen and nutrients to the cells, and remove waste materials, which are then eliminated with urination.

In a photochemical process a hydroen atom absorbs a 410 nm photon and shortly thereafter it emits a 2628 nm photon. what is the change in energy for the combination of these processes?
0.389×10^−19J is the change in energy for the combination of these processes.
λ1=410nm=410×10^−9m
λ2=2628nm=2628×10^−9m
E1−E2 = Energy absorbed by the atom in the process =hc[1/λ1−1/λ2]
=6.63×3[1/410−1/2628]×10^−9 = 0.389×10^−19J
We get, 0.389×10^−19J.

A sample of nitrogen gas is contained in a piston with a freely moving cylinder. At 0°c, the volume of the gas is 371 ml. To what temperature must the gas be heated to occupy a volume of 557 ml? report your answer in degrees celcius to the nearest whole number.
The gas must be heated to a final temperature of 137°C in order to fill a volume of 557 ml.
Given,V₁= 371mlV₂ = 557 mlT₁ = 0°C or 273 K
The final gas temperature that has to be heated must be determined.
As long as the cylinder is free to move, the pressure is always 1 atm, or equal to the external pressure.
Consequently, by using Charles Law, we obtain
V₁ / T₁ = V₂ / T₂
where starting and ultimate volumes V1 and V2, respectively T1 and T2 are beginning and ultimate temperatures, respectively (in Kelvin).
The ultimate temperature is as a result
T₂ = V₂ × T₁ / V₁Or, T₂ = 557 x (0+273) / 371Or, T₂ = 410 KOr, T₂ = 137°C.

which contains the most amount of energy an aluminum can at 30C or an aluminum can at 20C
Answer:
The can at 30 degrees had more energy.
Explanation:
Since Heat is a type of energy, and the first can (30C) is hotter than the second can (20C) you can see that it has more energy. Energy is related directly to heat.
The aluminum can at 30 degrees had more energy.
What is energy?Energy is defined as using physical or chemical resources to generate power, particularly to provide heat and light or operate machinery. People have figured out how to transform energy from one form to another and then use it to accomplish tasks, making modern civilization possible. Although energy can take on several forms, it cannot be created or destroyed.
Given that heat is a sort of energy and that the first can is hotter (30C) than the second can (20C), you can infer that the first can has more energy. You need to apply 0.90 J of heat in order to raise the temperature of 1 g of aluminum by 1 C. Under the same circumstances, the temperature of the aluminum varied less than that of the copper.

What is the forward rate with continuous compounding for a three-month period starting in one year?
Answer:8.7%
Explanation:
The forward rate for a three-month period starting in one year is 11.36% per annum.
The forward rate for a specific time period represents the interest rate for borrowing or lending money during that period in the future.
Let's denote:
[tex]r_1[/tex] = Spot rate for one year (annual rate)
[tex]r_2[/tex] = Spot rate for one year and three months (annual rate)
The formula for the forward rate with continuous compounding is given by:
[tex]\[ F = \frac{e^{(r2 * t2)} - e^{(r1 * t1)}}{t2 - t1} \][/tex]
where:
F is the forward rate
[tex]t_1[/tex] is the starting time in years (one year)
[tex]t_2[/tex] is the ending time in years (one year and three months)
Substituting the value
[tex]\[ r_1 = 9.5\% \\r_1 = 0.095)[/tex]
[tex]r_2 = 0.096\\\[ t1 = 1 \text{ year} \][/tex]
[tex]\[ t2 = 1 + \frac{3}{12}[/tex] = 1.25 year back to the formula as
[tex]\[ F = \frac{e^{(0.096 * 1.25)} - e^{(0.095 * 1)}}{1.25 - 1} \][/tex]
[tex]\[ F = \frac{e^{0.12} - e^{0.095}}{0.25} \][/tex]
[tex]\[ F = \dfrac{1.1275 - 1.0991}{0.25} \][/tex]
[tex]\[ F= \dfrac{0.0284}{0.25} \][/tex]
F= 0.1136
Now, convert the forward rate back to percentage:
Forward rate (F) ≈ 0.1136 * 100% = 11.36%

Volume is a measurement of three-dimensional space that is occupied. Numerous imperial units or SI-derived units, such as the cubic meter and liter, are frequently used to quantify it numerically (such as the gallon, quart, and cubic inch). Volume and length (cubed) have a symbiotic relationship. The volume of a container is typically thought of as its capacity, not as the amount of space it takes up. In other words, the volume is the amount of fluid (liquid or gas) that the container may hold.

Solve the simultaneous equation
-4x+3y=1
6x-y=2
Answer:
x = 1/2 y = 1
Step-by-step explanation:
Now form equation for y,
→ 6x - y = 2
→ y = 6x - 2
Then the value of x will be,
→ -4x + 3y = 1
→ -4x + 3(6x - 2) = 1
→ -4x + 18x - 6 = 1
→ 14x = 1 + 6
→ x = 7/14
→ [ x = 1/2 ]
Hence, the value of x is 1/2 (or) 0.5.
Now the value of y will be,
→ y = 6x - 2
→ y = 6(1/2) - 2
→ y = 3 - 2
→ [ y = 1 ]
Hence, the value of y is 1.
