We have that the time, to the nearest minute, when the water level is at 1.125 m for the second time after midnight is

From the Question we are told that
Maximum height 
Minimum height 
Time for next high tide will occur
Generally Average Height

Therefore determine Amplitude to be

Generally, the equation for Time is mathematically given by
At t=0

Where

Therefore

Hence the Time at
is

b) by the end of the fifth day, group b will be more than one cm taller than group a. eliminate
Explanation:
The correct prediction based on the data shown is that by the end of the fifth day, group B plants will be more than 1cm taller than group A plants.
let us examine the table closely;
Day Group A (Water Only) Plant Height (cm) Group B (Water and Fertilizer)
1 2.0 2.0
2 2.2 2.3
3 2.3 2.8
4 2.5 3.2
5 2.6 3.8
We can see that by the end of the fifth day, the height differences between the two plants, 3.8 - 2.6 = 1.2cm, this is greater than 1cm. This claim from the experiment is very correct.
Other predictions are false.

By converting the 400 nm wavelength of violet light into meters we are get 4.0.10^-7.
What is wavelength?
Wavelength can be defined as the distance between two successive crests or throughs of a wave. It is measured in the direction of the wave. The wavelength of light defined as the distance between the two successive crests or throughs of the light wave.The wavelength of light is the distance between corresponding point in two adjacent light cycles and the frequency.
