Given that,
Bulk modulus 
Change in volume 
Edge 
The volume of the cube at the ocean's surface will be

Where, a = edge
Put the value into the formula


We need to calculate the change in pressure
Using formula of pressure

Put the value into the formula


The pressure increases by
for every meter of depth
We need to calculate the depth
Using formula for depth


Hence, The depth is 9.75 m.
the speed of sound in water is slower than the speed of air
Answer:
Option e. Blue/Violet
Explanation:
We know that when white light passes through a diffraction grating it spits into a band of seven colors or spectrum which includes the color in the order VIBGYOR that stands for Violet, Indigo, Blue, Green, Yellow, Orange and Red respectively.
Red light has the longest wavelength and is least scattered whereas Violet light with the shortest wavelength is the one to get most scattered and as we move far from bright spot at the center, there is an increase in the wavelength of light, thus the color that corresponds to the closest one is Violet with the shortest wavelength in the band.
