Answer:
Explanation:
As the sum of the two right directed forces match exactly the left directed force, the only unbalanced force, and thus the net force, is the upward 25 N force.
Spectrophotometry is a method used to measure how much a chemical substance absorbs light by measuring the intensity of light as a beam of light passes through sample solution. the basic principle is that each compound absorbs over a certain range of wave length.

can you please post the chart as well
Answer:
3 m
Explanation:
It is given that,
The wavelength of a sound wave is 3 m.
We need to find the distance from a compression center to the adjacent rarefaction.
We know that, sound is a longitudinal wave. It travels in the form of compression and rarefaction.
Also, the distance between compression center to the adjacent rarefaction centre is called wave. Hence, the required answer is 3 m.
