DNA is the molecule from which RNA is produced so the answer is:
a) the molecule from which RNA is produced
Answer:
Sound is a type of energy made by vibrations. When any object vibrates, it causes movement in the air particles. These particles bump into the particles close to them, which makes them vibrate too, causing them to bump into more air particles. This movement, called sound waves, keeps going until they run out of energy.
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,
Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,
Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,
If V = 2V and p = 2P
Then,
Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
