C: Karl Schwarzschild correctly analyzed the relationship between the size of a black hole and its mass.

Explanation:

Karl Schwarzschild correctly analyzed the relationship between the size of a black hole and its mass. The correct option is C.

A black hole is an area of spacetime in which gravity is so powerful that nothing, not even light or other electromagnetic waves, can escape. According to general relativity theory, a sufficiently compact mass can bend spacetime to generate a black hole.

Karl Schwarzschild, a German physicist, was the first to "find" black holes. In 1915, he proposed a general relativity solution that was applicable to the simple (i.e., nonrotating, uncharged, and boring) example of a perfectly spherical object contained in otherwise empty space.

These suggestions are now known as the Schwarzschild radius and the singularity. Every item is allocated a Schwarzschild radius, which is determined by the object's mass. Gravity's behaviour begins to become strange within this radius.

The statement which summarizes cellular respiration is Oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

Cellular respiration is the process by which food, in the form of glucose is transformed into energy within cells.

The food is prepared by the plants by the process of photosynthesis in presence of sunlight. This food is in the form of glucose.

The respiration of plants is done by breaking of glucose by absorbing oxygen. This produces  carbon- di- oxide and water along with the release of energy.

Thus, the cellular respiration is oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

The correct answer from each drop-down menu is thermal energy moves from A to B by conduction the heat transfer will continue until the liquid in B reaches the same temperature as the liquid in A.

Good thermal conductors have an atomic or molecular arrangement that has the property of transferring heat to nearby atoms or molecules until the entire object is in thermal equilibrium. To understand better, let's take a metal bar as an example, which is a good thermal conductor.

In this case, the  thermal energy moves from A to B by conduction the heat transfer will continue until the liquid in B reaches the same temperature as the liquid in A.

We've got m/s, which is value of distance ÷ time

(distance/time)

3 x 10^8 is:

300,000,000m/s

1km = 1000m

1hr = 3600secs

So, divide 300,000,000m by 1000 to get in km & you get:

300,000km

Now divide this value by 3600 seconds to get it in km/hr

300,000km/3600 = 83.33333333

Thus, answer is 83.3km/h

Or

8.33 x 10^1 km/h (in standard form)

(doing 83.3 recurring multipled by 1000 & 3600 gets you back to original answer. So, 83.33333...x1000x3600= 300,000,000)
