Shockers acts as a shock absorber in the vehicle making the ride comfortable. When vehicle goes on rough road then it gets shocks from the road deformities the springs present in the shockers provide counter force and thus making the vehicle stable ride without shock.

In optics, chromatic aberration (abbreviated CA; also called chromatic distortion and spherochromatism) is an effect resulting from dispersion in which there is a failure of a lens to focus all colors to the same convergence point.[1] It occurs because lenses have different refractive indices for different wavelengths of light. The refractive index of transparent materials decreases with increasing wavelength in degrees unique to each.
Explanation:
a) photovoltaic cell is a semiconductor device and it converts light energy to electrical energy
b) burning of coal converts chemical energy to heat energy
c) rubbing of both hands against each other converts mechanical to heat energy
Answer:
Ex1.
a) Carbon : atomic number Z = 6 and mass number A = 12
b) Protons = 6; electrons = 6 ; neutrons = 6.
Ex2.
Molar mass of H₂O₂ = 34 g; BaF = 156 g; CO = 28 g.
Explanation:
Ex1.
a) the element with atomic number 6 and mass number 12 is carbon
b) number of protons and electrons in a element is given by its atomic number; and for neutrons its mass number - atomic number (A-Z).
⇒ protons = Z = 6; electrons = Z = 6.; neutrons = A-Z = 12-6 = 6.
Ex2.
Molecular formula of hydrogen peroxide is given by H₂O₂.
⇒ molar mass = 2×mass of hydrogen + 2×mass of oxygen
⇒ molar mass = 2×1 + 2×16 = 34.g
molar mass of BaF = mass of barium + mass of fluoride.
= 137 + 19 = 156 g
molar mass of CO = mass of carbon + mass of oxygen
= 12 + 16 = 28 g
