Answer:
600,000,000 degree C
Explanation:
This stage is the last stage and is refereed to as supernova. In the beginning of this stage, gravity pulls the inner core and crush it, due to which fusion of atoms starts. Carbon and Oxygen fuse together and the temperature is about of 600,000,000 degree C.
The most heavier atom that can be formed out of this fusion is the iron. The moment all the atoms becomes of iron, no further fusion is possible hence that body emits radiation of high intensity and collapse causing a big supernova.
Answer:
10 km/L
Explanation:
Given the following from question:
Efficiency of car engine = 25% = 0.25
Average force = 1000 N
Gasoline energy content = 40,000,000 J/L
therefore:
Energy utilized effectively = Efficiency of car engine * Gasoline energy content
Energy utilized effectively = 0.25 * 40,000,000 = 10,000,000 J/L
Distance obtain by car in kilometer per meter = Energy utilized effectively/Average force
Distance obtain by car in kilometer per meter = 10,000,000/1000 = 10,000 m/L = 10 km/L
10,000 meter per liter = 10 kilo meter per liter
Answer: d
Explanation:
Did you actually try to answer the question its obviously d they all have same miles per hour as 100 so there would be nothing different so it would be d.
Answer:
Every object has a different density and therefore carries different properties. When rays of white light strike an object, each ray light strikes the object with different frequency and therefore is absorbed and reflected differently from the host object.
In case if all the frequencies are absorbed by the object, it turns out to be black in color. Whereas on the other hand, if it is a mix of absorption and reflection, it makes different colors based on its frequencies and other properties of the object.
