#1) Why do coal-burning power plants and oil refineries have tall smokestacks?
Answer: They are gas combustion devices used in industrial plants such as petroleum refineries, chemical plants, natural gas processing plants as well as at oil or gas production sites having oil wells, gas wells, offshore oil and gas rigs and landfills. In industrial plants, these are primarily used for burning off flammable gas released by pressure relief valves during unplanned over-pressuring of plant equipment.

EXPLAIN why most earthquakes occur at the boundaries of different tectonic plates
olga nikolaevna [1]

Answer:

Explained as below

Explanation:

  • The three types of pf plate boundaries are spreading zones, transform faults and subduction zones. Most earthquakes occur along the boundaries of plate tectonics due to the effects of the earth's mantle layer that acts as a recycling agent and recycles 99% of the earth's surface layers from above.
  • Various tectonic forces and process act son these slabs and rocks from above and hence through the activities of erosion and denudation of the rocky masses these plates collide with each other as the earth is it's self not static its dynamic and moves continuously on a regular basis and hence changes take place on the surface of earth.
  • Thus it can be seen that the earthquakes and volcanic events occur at the plate boundaries and hence produce or are responsible for the various activities.

Estimate the total charge q on the cloud when the breakdown of the surrounding air is reached
slega [8]
 First, you must <span>breakdown electric field:
E = 9x10^9 q / R^2
where R is the radius of the cloud
q is the required charge. 

So this will come up to a solution of: 
q = E R^2 / 9x10^9
= 3 x10^6 x (500)^2 / 9 x10^9 

= 83.33 C.

The answer is 83.33 C.</span>
