    First law: The motion of any object will not change unless any force work on it. Second law : The acceleration produced by the total force of an object will directly proportional to the magnitude in same direction and inversely proportional to the mass of the object. Third law : Every action, there is an opposite and equal reaction.

    3Thank You

    Adithya Dev A 4 years, 8 months ago

    Newton first law of motion, also known as law of inertia, states that anything in rest/motion remains in the same state unless and until an external force is applied on it. The second law states that the rate of change of momentum of an object is directly proportional to the force applied on it. The third law states that every action has an equal and opposite reaction.

    Newton First Law. Anything in motion it remains in motion anything in Rest it Remains in Rest unless it compelled by external force act upon it.

    When we pass the light from a glass slab, the incident ray become parallel to the emergent ray while when we pass a Ray of white light from prism, it splits into seven colours. The colours are the opposite order of VIBGYOR . In prism, the light of incident it is not parallel to the light of emergence.

    On passing through glass slab, a light ray gets refracted and emerges out the glass slab in a direction parallel to the direction of incident ray. This occurs due to the presence of a lateral shift. Whereas, on passing through a glass prism, light rays get deviated in a direction not parallel to the incident ray. Rather, it deviates at the angle of deviation.

    5Thank You

    Vikas Maurya 4 years, 8 months ago

    . In refraction with glass prism the white light ? gets converted into 7 different colours which are : - V=Violet -I =Indigo -B =Blue -G =Green -Y =Yellow -O =Orange -R =Red While .In refraction with glass Slab the white light only gets refract from its original path.It gets bend away from normal.

    There are two reasons behind why Bile is important for digestion of fats though it lacks an enzyme. 1) It breaks down large fat globules into smaller fat droplets causing the emulsification of fats so that a greater surface area is available for faster action of lipase. 2) It provides an alkaline medium for activating lipase.

    Electric fuse is a safety device which is used to protect devices from overflow of current through them. It is usually made of metals with low resistivity and low melting point like copper or an alloy of lead and tin and is connected in series with domestic electric circuits. When excess current flows through the circuit, the circuit gets overheated. The heat produced exceeds the low melting point of the fuse material and thus, melts it off disconnecting the circuit.
