Answer:
True
Explanation:
Stellar-sized black holes form when a star explodes in a supernova is a true statement. Supernova occurs when a huge size star collapses into itself. This explosion is massive such that parts of the stars are thrown apart. And this phenomenon gives rise to super massive black holes. Supernova occurs when the core becomes very heavy and star is not able to hold its won weight.

Answer: Option (c) is the correct answer.
Explanation:
When the child is tossed up into the air then she gains kinetic energy as the child has moved from its initial position.
It is given that mass is 20 kg, velocity is 
, and height is 2 m.
Calculate the kinetic energy of child as follows.
kinetic energy = 
= 
= 
= 
Also, when child falls off the ground then she will have gravitational potential energy.
Calculate gravitational potential energy of child as follows.
Potential energy = m × g × h
= 
=
