Answer 2

Answer:

4. Burning dry leaves.. it's the correct option because burning of dry leaves doesn't reduces pollution, instead it increases air pollution.. hope it helps..

Explanation:

Astrophysicists Surprised to Find Extreme Black Holes Have “Gravitational Hair” That Can Be Combed

Black holes can be fully characterized by only three physical quantities: their mass, spin and charge. Since they have no additional “hairy” attributes to distinguish them, black holes are said to have “no hair”: Black holes of the same mass, spin, and charge are exactly identical to each other.

Dr. Lior Burko of Theiss Research discovered that a special kind of black hole violates black hole uniqueness, the so-called “no hair” theorem. Specifically, the team studied extremal black holes — holes that are “saturated” with the maximum charge or spin they can possibly carry.

They found that there is a quantity that can be constructed from the spacetime curvature at the black hole horizon that is conserved, and measurable by a distant observer. Since this quantity depends on how the black hole was formed, and not just on the three classical attributes, it violates black hole uniqueness.
