Answer:N=1151724138 atoms
Explanation:The atomic radius of molybdenum atom is 145 picometers so lining up molybdenum atoms is like lining up the beads of radius 145 picometers
so one bead would cover the length of 145*2=290 picometers
hence the atom's diameter =D=290 picometers
D=290 *10^(-12)

also
Distance span= 33.4 cm
Distance span= 0.334m
As the Distance span adds up with no of atoms the resulting formula is
Distance span by atoms= No of atoms * atom's diameter
so

Answer:
Mixing colored lights & mixing colored paints. The primary colors of light are also known as the additive colors, because, when you add these three colors of light (red, green and blue) your brain perceives white light. The primary colors of paints, however, are known as subtractive colors.
Explanation:
<em>Your </em><em>well-wisher</em>
When parallel rays exit a concave lens, the light rays are divergent.
The rays diverge or bend away from the axis it has been traveling upon entering the lens when it reaches the other side of the lens. These rays appear to have come from the same focal point before entering the concave lens. When these parallel rays are extended, it will be traced back to a single point of origin.
