Explanation:
It is given that,
The time period of artificial satellite in a circular orbit of radius R is T. The relation between the time period and the radius is given by :

The radius of the orbit in which time period is 8T is R'. So, the relation is given by :



So, the radius of the orbit in which time period is 8T is 4R. Hence, this is the required solution.
Answer:
CH3NH2 : Hydrogen bonding and London dispersion forces
F2 : Hydrogen bonding, dipole-dipole and London dispersion forces
NOF : Dipole-dipole forces
C2H6 : London dispersion forces
H2O : Hydrogen bonding and London dispersion forces
Increasing order of boiling point:
F2
C2H6
NOF
CH3NH2
H20
Explanation:
London dispersion forces exist in all substances
CH3NH2 : The hydrogen bonding in the amine group and the assymetry of the molecule makes the hydrogen bonding and dipole-dipole bonds from the methyl group.
F2 : The bond is non polar because its a homonuclear bond
NOF : Dipole-dipole forces due to difference in elecronegativity between all the atoms involved and assymetry
C2H6 : London dispersion forces because all dipole-dipole forces are cancelled out due to the symmetry of the molecule
H2O : Hydrogen bonding between hydrogen and oxygen and the assymetry of the molecule
Order of boiling points: London dispersion forces, followed by dipole-dipole forces and hydrogen bonding is the strongest
It is a solution, because it's the alloy of tin and copper
The correct word to fill the blank in the sentence is "capillaries". The thinnest blood vessels in your body are the capillaries. These are the blood vessels that blood is able to transfer sugars and oxygen into the tissues.
