E = hf = hc/λ
= (6.6 x 10^-34) × (3 × 10^8) ÷ (3.1 × 10^-7)
=6.138 × 10^-32 J
Motion is a change in position measured by distance and time.
False because absolute magnitude is the real magnitude but apparent is not
Answer:
Explanation:
Given that
At starting separated = 1.20m
And the increase in background noise by Δβ = 5 dB, due to which the level of sound also rises
Based on the above information, the separation rf that is needed is shown below:
As we know that
Hence, the separation r_f i.e. required is
We simply applied the above equation so that the correct separation could come
