Dear student 
The explanation for second part :
The weight of an object is a force. It is the force with which a body is attracted toward Earth or another celestial body. This means that when you are in space, away from Earth, objects do not weight anything since they do not feel gravitational attraction to the Earth.
What objects have though in space is mass. This is because mass is defined as the amount of material an object contains, and that doesn't change whether the object is on Earth, on the Moon, or anywhere in space.

Dear student 
Ignore the first one 
Dear student 
Put the value of x in the equattion 
x = 3 - √5 
let y =  root x / root 2 + root( 3x-2)
y^2 = x / (2+(3x-2)+2√(6x -2))
put the value of x in this 
y^2 = (3-√5 )/ (2+ (7-3√5)+2√(16-6√5)
calculate this the ans would be 1/(sqrt 5 ) 
Option D is correct 
Good Luck
