Answer:
time taken to cook on the pressure cooker = 100 seconds = 1.67 mins
Explanation:
Given: wavelength of Nitrogen laser (∧) = 337.1 nm = 337.1 X 10^-9 m
We know that, Energy of photon (E) = hc/∧ = hv
where, v = frequency of photon and c = speed of light = 3 X 10^8 m/s
Thus, v = c/∧ = (3 X 10^8)/ (337.1 X 10^-9) = 8.899 X 10^14 s-1.
Answer: F<span>requency of nitrogen laser = </span>8.899 X 10^14 s-1.
Communication will be the answer
Answer:
Sound energy is the form of energy generated when an object vibrates. Once produced through vibrations, sound energy is transferred in waves through mediums such as air and water before it reaches your ears.
