The speed of sound I gases depends on a humidity b air c temperature d visibility

Physics
1 answer:
Mazyrski [523]3 years ago
4 0

The speed of sound in gases is represented mathematically as:

v(sound)  = √γRT/M

where γ = adiabatic constant which is the ratio of the heat capacities at constant pressure and constant volume; Cp/Cv

R = gas constant

T = temperature

M = molar mass of the gas

Hence, the speed of sound in gas is directly proportional to the square root of temperature.

Ans: c) temperature

Answer:

Weight = 8.162 Newton.

Explanation:

Given the following data;

Mass = 2.2 kg

Acceleration due to gravity = 3.71 N/kg

To find the weight of the textbook;

Weight = mass * acceleration due to gravity

Weight = 2.2 * 3.71

Weight = 8.162 N

Therefore, the weight of the science textbook in mars is 8.162 Newton.

If the PLATE SEPARATION of an isolated charged parallel-plate capacitor is doubled: A. the electric field is doubled
mash [69]

Explanation:

The electric field of an isolated charged parallel-plate capacitor is given by :

E=\dfrac{q}{A\epsilon_o}........(1)

Where

q is the electric charge

A is the area of cross section of parallel plate

It is clear from equation (1) that the electric field of a parallel plate capacitor is directly proportional to the charge on the plate and inversely proportional to the area of cross section of a plate.

So, the correct option is (E) i.e. "none of the above".

Alexxx [7]

Answer:

c. 0.12 m/s

Explanation:

by using momentum formula v_2=\frac{m_1\times v_1}{m_1+m_2}

we get

v_2=\frac{0.15\times 50}{0.15+65}=0.12
