IF A ROCK IS DROPPED INTO A GRADUATED CYLINDER WITH A VOLLIME OF 25 ML AND IT
RISES TO 29 ML, WHAT IS THE VOLUME OF
THE ROCK ?

Initial volume of graduated cylinder(v1) = 25 ml

Final volume (v2) =29ml

then,

volume of the rock (v) = v2 - v1

= 29 - 25 = 4 ml

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.

hope it

i think it is true since you can test the answer and can use observations to complete it.
