subject of the formula



Divide 10 by .05 and that is your answer
Underwater caves in Florida are primarily formed due to the abundance of limestone layers just situated below the ground, forming the "Floridan Aquifer." Layers of these limestones are believed to be thousands of meters thick. When rainwater is being seeped into the ground, it softens the calcite present in limestones due to its acidic nature until it is dissolved. This leads to the formation of cavities and tunnels which eventually becomes an interconnected network of passages over time. As water continues flowing through these passages, which builds up from the bottom of these cavernous empty spaces, underwater caves are then formed. Therefore, the first choice is the answer.
Answer:
Speed of light changes
Explanation:
Since glass is denser than air so the speed of light in glass is less than in air so light rays bend i.e. refract.
Running that process in a power plant would not only eliminate the
danger of a core meltdown, it would also pretty much eliminate the
possibility of getting any nuclear power out of the plant.
The understanding behind your question is correct . . . Neutrons coming
out of one fission go on to get absorbed in other nuclei, and cause the
other ones to fiss. BUT . . . NOT every free neutron whizzing around in
the core material gets absorbed. Some of them enter another nucleus
and immediately get spit out. And some of them never get near another
nucleus at all. Of all the neutrons produced in one fission, only some
percentage go on to stimulate another one. So if each fission produced
only one neutron, then the whole process would completely run out of gas
in some amount if time, as the number of free neutrons dwindled and shrank.
