Gravitational force = Gxm1xm2 /r^2
This equation depends only upon object's masses and distance between them. So option b is correct
B is the correct answer since acid corrode on metals such as carbon, steel, zinc and such.
The clothing seems white because the entire light is reflected.
<h2>what is absorption and reflection?</h2><h3>Absorption:</h3>
This occurs when light is transformed into another type of energy. This happens when light vanishes while travelling through another medium.
<h3>reflection:</h3>
It is referred to as light reflection when a light ray hits a polished, smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.

An atom is solid material
Answer:
1.11 dioptre
Explanation:
= Distance of the image = - (125 - 2) = - 123 cm
= Distance of the object = 54 - 2 = 52 cm
= Focal length of the lens
Using the equation
cm
Power of the lens is given as
Dioptre
