Answer:
Displacement method of volume measurement is no suitable
Explanation:
Displacement method of volume measurement is no suitable for the objects that do not get immersed into the water completely because of the hindrance in accuracy of the measurement.
Number 1 is D number 2 is C
Answer:
Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.
Explanation:
The bending of light as it passes into a transparent material of different optical intensity is known as refraction. The correct option among all the options given in the question is option "C".It can never be
reflection as reflection is the bouncing of the light from a surface and so
option “A” can easily be negated. The last option or option
“D”<span> conversion and it mean converting something to
another and that means a total change of form. So the last option should also
be negated. The second option can also be negated.</span>
