Question

four molecules of a gas have velocities 2,4,6 and 8km/s respectively calculate average speed.​

Answer 1

Answer:

The answer is 5 km/s

Explanation:

For Finding the average we need to add all the values i.e. 2 + 4 + 6 + 8 = 20

Now we need to divide it by 4 (since there are 4 molecules).

20÷4 = 20.

Hence, the answer.
