Assertion (A):
According to Nova hypothesis, Solar planets were formed because of explosion of Super Nova.
Reason (R):

Codes:
a) A is true, but R is false.
b) A is false, but R is true.
c) Both A and R are true, but R is not the correct explanation of A.
d) Both A and R are true and R is the correct explanation of A.
Answer »Answer: (c)
According to Nova hypothesis, Solar planets were formed because of explosion of Super Nova. A star becomes Super Nova in that stage when it has lacks hydrogen elements. A supernova happens where there is a change in the core, or center, of a star. A change can occur in two different ways, with both resulting in a supernova.
The first type of supernova happens in binary star systems. Binary stars are two stars that orbit the same point. One of the stars, a carbon-oxygen white dwarf, steals matter from its companion star. Eventually, the white dwarf accumulates too much matter. Having too much matter causes the star to explode, resulting in a supernova. The second type of supernova occurs at the end of a single star’s lifetime. As the star runs out of nuclear fuel, some of its mass flows into its core.
Eventually, the core is so heavy that it cannot withstand its own gravitational force. The core collapses, which results in the giant explosion of a supernova. The sun is a single star, but it does not have enough mass to become a supernova.

a) 4,000° Celsius
b) None of these
c) 5,000° Celsius
d) 6,000° Celsius
Answer »Answer: (d)
These measurements confirm geophysical models that say that the temperature difference between the solid core and the mantle above must be at least 1,500° C to explain why the earth has a magnetic field.
The research team, which was led by Agnes Dewaele from the CEA, a French technological research organization, used X-rays from the European Synchrotron Radiation Facility (ESRF) in Grenoble, France, as a key investigating tool.
