Question

Find the obscissa and ordinate of the point (4,-5)

Answer 1

Answer:

✏ The 'y' value is known as the ordinate. ✏ Any point on the coordinate system is represented as (x,y). So, here, the point (4,5) resembles x(abscissa) = 4 and, y(ordinate) =5

Answer 2

Answer:

Isotope, one of two or more species of atoms of a chemical element with the same atomic number and position in the periodic table and nearly identical chemical behaviour but with different atomic masses and physical properties. Every chemical element has one or more isotopes.A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
