Answer:
Explanation:
The refractive index of the suspected glass can be known by using the backe- line method. This process takes place in a petrographic microscope. In this method an oil comparable to the refractive index of the glass is used. At a point when the refractive index of the glass becomes equal to that of the oil in which it is immersed the yellow line under the observation of the plane polarized light gets disappeared. This method can be used to identify the refractive index of the suspect glass and comparing it with the source of origin or sample glass.

Answer:
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect. Click the image for a larger view. Coastal currents are affected by local winds.

Answer:
Producers have the largest amount of energy available.
Explanation:
According to Lindeman's Ten Percent Law, only 10 percent of energy is made available to the next trophic level while 90% of the energy captured from the previous trophic level is lost as heat to the environment . It means that when energy is passed in an ecosystem from one trophic level to the next, only ten percent of the energy will be passed on.
For example :-
Suppose a plant has total energy of 10,000J. When a herbivore will eat the plant , according to Ten Percent Law it will get 1,000J (10% of 10,000J). Now , when a carnivore will hunt and eat the herbivore , it will get only 100J (10% of 1,000J).
