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:

He's 3 miles west of school.

Explanation:

He went 5 miles up and 5 miles down which means that he really didn't go up or down. In between that, he went 3 miles west so if the 5 milers don't count, this puts him at 3 miles west of school.

A 0.73-m aluminum bar is held with its length parallel to the east-west direction and dropped from a bridge. Just before the bar

Tasya [4]

Answer:

A) B = 5.4 10⁻⁵ T, B) the positive side of the bar is to the West

Explanation:

A) For this exercise we must use the expression of Faraday's law for a moving body

fem = $- \frac{d \phi }{dt}$

fem = $- \frac{d (B l y}{dt}= - B l v$ - d (B l y) / dt = - B lv

B = $- \frac{fem}{l \ v}$

we calculate

B = - 7.9 10⁻⁴ /(0.73 20)

B = 5.4 10⁻⁵ T

B) to determine which side of the bar is positive, we must use the right hand rule

the thumb points in the direction of the rod movement to the south, the magnetic field points in the horizontal direction and the rod is in the east-west direction.

Therefore the force points in the direction perpendicular to the velocity and the magnetic field is in the east direction; therefore the positive side of the bar is to the West
