Which is the correct formula for cellular respiration?

6. Which Thanksgiving dish contains the most dietary fiber ? (Corn) (Mashed Potatoes) (Sweet Potatoes) (Pecan Pie)

pashok25 [27]

Answer:

The correct option is;

Sweet Potatoes

Explanation:

The dietary fiber in Corn = 2.7 g per 100 g

The dietary fiber in Mashed Potatoes = 1.3 g per 100 g

The dietary fiber in Sweet Potatoes = 3 g per 100 g

The dietary fiber in Pecan Pie = 2.1 g per 100 g

Therefore, the Thanksgiving dish that contains the most dietary fiber per 100 g is Sweet Potatoes

A length of wire is cut into five equal pieces. the five pieces are then connected in parallel, with the resulting resistance be

ycow [4]

The equivalent resistance of resistors connected in parallel is
$\frac{1}{R_{eq}} = \frac{1}{R_1} + \frac{1}{R_2} + ...$
In our problem, we have 5 identical resistor of resistance $R$ , so their equivalent resistance is
$\frac{1}{R_{eq}} = 5 (\frac{1}{R} )$
The problem also says that the equivalent resistance is $R_{eq}= 17 \Omega$ , so we can find the resistance R of each piece of wire:
$R=5 R_{eq} = 5 \cdot 17 \Omega = 85 \Omega$

In the initial wire, it's like the 5 pieces are connected in series, so the equivalent resistance of the wire is just the sum of the resistances of the 5 pieces:
$R_{wire} = 5 R = 5 \cdot 85 \Omega = 425 \Omega$

A glass tube 1.50 meters long and open at one end is weighted to keep it vertical and is then lowered to the bottom of a lake. W

Lilit [14]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The total pressure is $P_T = 10.79*10^{5} N/m^2$

The temperature at the bottom is $T_b = 284.2 \ K$

Explanation:

From the question we are told that

The length of the glass tube is $L = 1.50 \ m$

The length of water rise at the bottom of the lake $d = 1.33 \ m$

The depth of the lake is $h = 100 \ m$

The air temperature is $T_a = 27 ^oC = 27 +273 = 300 \ K$

The atmospheric pressure is $P_a = 1.01 *10^{5} N/m$

The density of water is $\rho = 998 \ kg/m^3$

The total pressure at the bottom of the lake is mathematically represented as

$P_T = P_a + \rho g h$

substituting values

$P_T = 1.01*10^{5} + 998 * 9.8 * 100$

$P_T = 10.79*10^{5} N/m^2$

According to ideal gas law

At the surface the glass tube not covered by water at surface

$P_a V_a = nRT_a$

Where is the volume of

$P_a *A * L = nRT_a$

At the bottom of the lake

$P_T V_b = nRT_b$

Where $V_b$ is the volume of the glass tube not covered by water at bottom

and $T_b$ i the temperature at the bottom

So the ratio between the temperature at the surface to the temperature at the bottom is mathematically represented as

$\frac{T_b}{T_a} = \frac{d * P_T}{P_a * h}$

substituting values

$\frac{T_b}{27} = \frac{0.133 * 10.79 *10^5}{1.01 *10^{5} * 1.5}$

=> $T_b = 284.2 \ K$

What is the process used to separate the mixture of flour and rice?

Veseljchak [2.6K]

1. Take a breaker
2. Put a sieve on it
3. Pour the mixture and shake the sieve gently
4. Wait for the flour to fall. After the flour falls pour the rice from the sieve into other beaker then do experiment again for fair testing(optional)
