The cost of full ticket for a journey is Rs. 27:54. An adult pays full and a child pays only at half rate. How much will be the cost of the journey for a family having two adults and two children? ​

Answer:

Instruments used in collecting data through survey research

There are four main survey data collection methods – Telephonic Surveys, Face-to-face Surveys, and Online Surveys.

Explanation:

But why is ur mood offed?

what happened :)

Answer:

A method of collection of data is determined by conducting a survey.

Explanation:

• One can collect data from a large sample size or research population using surveys.
• This enhances the validity and precision of your research findings.
• When compared to other research methodologies, the cost of producing and executing a survey is usually lower.
• Telephonic surveys, face-to-face surveys, and online surveys are the four basic survey data gathering modalities.
• Survey research is a quantitative research approach for gathering information from a group of people known as a panel of respondents.

Hence, the collection of data through conducting a survey is one of the methods used.

The molecular weight of CO

is 44.

So, the gas is CO

.

Answer:

The molar mass of the gas is 6758 g/mol.

Given:

Density of gas, ρ = 94 mg/cc = 0.094 g/cc

Temperature, T = 15°C = 15+273 = 288 K

Pressure, P = 250 mm of Hg = 250/760 atm = 0.3289 atm

Find:

Molar mass of gas.

Solution:

According to Ideal gas equation, we have

PV = nRT             ------------------- (i)

where P = Pressure of gas

V = Volume of gas

n =Number of moles of gas

R = Universal gas constant = 0.0821 L atm K⁻¹mol⁻¹ = 82.1 cc atmK⁻¹mol⁻¹

T = Temperature of gas

Now, Number of moles of the gas = m/M

where m = mass in gram

M = Molar mass of the gas

Putting the value of n in equation (i), we get

[tex]PV = \frac{m}{M} RT[/tex]

[tex]PM=\frac{m}{V} RT[/tex]

But m/V = Density of gas, ρ

[tex]PM = \rho RT[/tex]

[tex]M = \frac{\rho RT}{P}[/tex]

Putting values in the above formula, we get

[tex]M = \frac{(0.094)(82.1)(288)}{0.3289}[/tex]

[tex]M = 6758 g/mol[/tex]

Hence, the molar mass of the gas is 6758 g/mol.

Answer:

IN disciplinary

hope it is useful

Prefixes for disciplinary can be - In, inter

• Prefix are the words that we place before another word to slightly change its meaning.

• The meaning of the word with a prefix is still a derivative of the root word.
• For a given word, like disciplinary in this case there can be many possible prefixes.
• For eg- in disciplinary, interdisciplinary, transdisciplinary, multidisciplinary.
