The resultant speed of the plane is (3) 226 m/s
Why?
We can calculate the resultant speed of the plane by using the Pythagorean Theorem since both speeds are perpendicular (forming a right triangle).
So, calculating we have:


Hence, we have that the resultant speed of the plane is (3) 226 m/s

<u><em>Loudness</em></u><em> refers to how a sound seems to a listener, whether it's loud or soft. </em>
<em>___________________________</em>
<u><em>Intensity </em></u><em> is the sound power per unit area. It is independent of the sensitivity of the human ears.</em>
<em>___________________________</em>
<em>The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).</em>

The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Given:
rate of effusion of Helium = 6 hours
Data needed:
Molar mass of hydrogen gas = 2 g/mol
Molar mass of helium gas = 4 g/mol
Assume:
Constant conditions such as temperature and pressure.
Required:
rate of effusion of Hydrogen gas
Solution:
To solve the problem, we can use the formula:
rate of effusion of A/ rate of effusion of B = (molar mass of B/molar mass of A)^1/2
substituting values,
rate of effusion of hydrogen gas/ 6 hours = (4 g/mol/2 g/mol)^1/2
rate of effusion of hydrogen gas = 8.5 hours
