The milky way is held together by a black hole's gravitational force. since the stars near this black hole move at a high speed, what can you infer about the black hole? a. its location b. its depth c. its speed d. its size

A. Location

Explanation:

A black hole is a massive structure in the space from which light cannot escape. Therefore, the depth of the black hole (B), the speed (C), and size (D) are extremely difficult to measure. However, scientists have been able to locate the position of black holes via the movement of stars and gases around it. Typically, since black holes are extremely dense objects, masses spins around the black holes and form a structure called an accretion disk. By looking at the speed of stars, the scientists can detect where the black holes are in the space.

answer: ice crystals in air

the water from the water body or another source of water gets evaporated as water vapor as an effect of heat on water. these water vapor rises in the upper layers of the earth atmosphere under high atmospheric pressure. the atmospheric pressure of these water molecules starts to decrease due to the effect of cold air. the invisible water vapor condenses into visible water droplets and ice crystals.these ice crystals and water droplets being less denser than the surrounding air floats on air as clouds.
