Which of the following states the law of universal gravitation? A: Objects tend to resist a change in motion
B: Every object in the universe attracts every other object
C: Energy cannot be created or destroyed in an isolated system
D: Particles with like charges will repel each other

its A,

Step-by-step explanation:

Newton's law of gravitation, statement that any particle of matter in the universe attracts any other with a force varying directly as the product of the masses and inversely as the square of the distance between them.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
