Answer:
364 nm
Explanation:
The formula for the energy (E) of a photon in terms of its wavelength λ is
E = hc/λ
We can rearrange this formula to give
λ = hc/E
If E = 5.45 × 10⁻¹⁹ J, then

The different types of electromagnetic radiation shown in the electromagnetic spectrum consists of radio waves, microwaves, infrared waves, visible light, ultraviolet radiation, X-rays, and gamma rays.
Answer:
35 minutes
Explanation:
The flow rate of the stream is the rate of volume of water with respect to time. It expresses the volume of water flowing per unit time.
Flow rate = 
From the given question,
average flow rate of the stream = 420 cubic meters per minute, and the required volume = 14700 cubic meters.
So that;
time = 
= 
= 35
time = 35 minutes
Therefore, with the given average flow rate, the steam will produce 14,700 cubic meters of water in 35 minutes.
IT will be Refraction of light
Answer:
C
Explanation:
Since the solution have an observable color, that means that it absorbs light in the visible region hence it can be determined by colorimetry. Secondly, KMnO4 is a reducing agent which can be titrated against an oxidizing agent and it's concentration accurately determined.
