Answer: Sea otter is the pioneer species in the kelp forest as it regulates and controls the population of other species in the kelp forest.
Explanation:
If sea otters are hunted and their population is brought to extinction then this will cause major harm the ecosystem of the kelp forest and it will disturb the ecological balance in the kelp forest. The herbivorous animals consumed by the sea otters will increase in population and they will consume a lot of vegetation in the forest. The kelp forest which forms the coastline will not remain effective in providing protection against the storms to the neighboring areas.
Answer:
Polarizing angle,
Given:
Critical angle,
Solution:
Now, in Total Internal Reflection (TIR), the critical angle for cubic zirconia is given by:
(1)
where
= refractive index of zirconia
From eqn (1):
Now, the angle of polarization is given by:
tan
Therefore,
Answer:
The intensity of a light from the source at a distance of 10 meters is 0.0026 foot-candle.
Explanation:
Given that,
Distance from the source = 2 meter
Intensity = 0.065 foot -candle
New distance = 10 m
We know that,
The intensity I of light varies inversely with the square of the distance from the source.
We need to calculate the value of constant
Using formula of intensity
Put the value into the formula
We need to calculate the intensity
Using formula of intensity again
Put the value into the formula
Hence, The intensity of a light from the source at a distance of 10 meters is 0.0026 foot-candle.
