pls help I will mark brainliest. Someone made a copy of an analog wave and a digital wave. Compare the copies with the original

waves. Then, explain which type of wave is a more reliable way to encode and transmit information.

ANSWER ASAP GIVING BRAINLIEST FIVE STARS AND A HEART!

Leto [7]

Answer:

Nothing

Explanation:

Thermal energy and heat are mainly related because of the fact that the faster molecules move, the more heat is created. If molecules are vibrating slower, that means that there will be less energy, resulting in less heat. Say I am boiling water. As the temperature increases, the water molecules move faster. Once that water cools, the molecules will be moving really slowly. In conclusion, thermal energy and heat are related because of how fast or slow the molecules move, the more or less heat and energy will be produced. I hoped this helped!

A sample of sodium hydroxide (NaOH) has a mass of 160. 0 g. The molar mass of NaOH is 40. 00 g/mol. How many moles of NaOH does

Andrew [12]

4 moles of NaOH is present in the given 160 grams of NaOH.

<h3>How we calculate moles?</h3>

Moles of any substance will be calculated as:

n = W/M, where

W = given mass of NaOH = 160 grams (given)

M = molar mass of NaOH = 40 g/mole

Moles of NaOH is calculated as:

n = 160g / 40g/mol = 4 moles

Hence, moles of sodium hydroxide (NaOH) is 4 moles.

Fynjy0 [20]

Answer:

Neither arre correct

Explanation:

Neither Anya nor Braden are correct. This is because if you use 90 degrees, 180 degrees, or even 270 degrees you will not get the exact image, which means that the image will not be found by just a rotation because there will be a curve in the image. You can solve it if you can do 90 degree rotation and translation.

A tank has a volume of 0.1 m3 and is filled with He gas at a pressure of 5 x 106 Pa. A second tank has a volume of 0.15 m' and i

GarryVolchara [31]

Answer:

$P=5.6*10^{6} Pa$

Explanation:

Consider that, as the system is adiabatic, $U_{1}= U_{2}$ where U1 and U2 are the internal energies before the process and after that respectively.

Consider that: $U=H-PV$ , and that the internal energy of the first state is the sum of the internal energy of each tank.

So, $H_{1}-P_{1}V_{1}=H_{2}-P_{2}V_{2}\\H_{1}^{A} -P_{1}^{A}V_{1}^{A}+H_{1}^{B} -P_{1}^{B}V_{1}^{B}=H_{2}-P_{2}V_{2}$

Where A y B are the tanks. The enthalpy for an ideal gas is only function of the temperature, as the internal energy is too; so it is possible to assume: $H_{1}=H_{2}\\H_{1}^{A}+H_{1}^{B} =H_{2}$

So, $P_{1}^{A}V_{1}^{A}+P_{1}^{B}V_{1}^{B}=P_{2}V_{2}$

Isolating $P_{2}$ ,

$P_{2}=\frac{P_{1}^{A}V_{1}^{A}+P_{1}^{B}V_{1}^{B}}{V_{2}}$

$V_{2}=V_{1}^{A}+V_{1}^{B}=0.25m^{3}$

So,

$P_{2}=\frac{5000000*0.1+6000000*0.15}{0.25}=5600000Pa=5.6*10^{6} Pa$

How many molecules are in 2L of water vapor at STP?

JulsSmile [24]

Answer:

5.4 x 10²²molecules

Explanation:

Given parameters = 2L

Unknown; number of molecules

Condition of the water vapor is at standard Temperature and Pressure

Solution

To solve this problem, we simply find the number of moles the given volume would yield at STP using the relationship below:

Number of moles = $\frac{volume occupied}{22.4}$

Number of moles = $\frac{2}{22.4}$ = 0.089mole

To find the number of molecules in the solved mole of the water vapor:

we use the avogadro's constant to evaluate.

1 mole of a water vapor = 6.02 x 10²³ molecules

0.089 mole of water vapor = 0.54 x 10²³molecules

Number of molecules of water is 5.4 x 10²²molecules
