Here we have to find the diameter of nucleus as the
diameter of atom is given.
Diameter of atom is 1 x 10⁻⁸ cm
Radius of atom = diameter/2
so, radius of atom = 1 x 10⁻⁸ cm/2
= 5 x 10⁻⁹ cm
To find diameter of nucleus, first we have to find the
radius of nucleus by using this formula,
R = rA⁽¹/³⁾ where <span>R = radius of nucleus, r = radius of atom and A is a nucleon
number, which is different for every atom
so, R=(5x10</span>⁻⁹)A⁽¹/³⁾
here atom is not mentioned, so we don't know the value of A
and Dimeter (D) = 2R, R = D/2
D/2 = (5x10⁻⁹)A⁽¹/³⁾
Diameter of nucleus (D) = 2((5x10⁻⁹)A⁽¹/³⁾)
Answer:
Nicotine
Explanation:
Tobacco smoke contains numerous toxic chemicals including organic carcinogens such as polycyclic aromatic hydrocarbons and aromatic amines, inorganic carcinogens such as polonium 210, and arsenic and toxic alkaloids such as nicotine. Nicotine extracted from tobacco has also been used as an insecticide.

Answer:
Anomalous expansion
Explanation:
Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.
At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.
When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.
This way, organisms can survive in the water due to the lower layer not freezing.
