Answer:
Dipole-Dipole attraction
Explanation:
Dipole-dipole attraction is a type of vander waals forces found in the molecules of sulfur dioxide.
Vander waals forces are weak attractions joining non-polar and polar molecules together. They are of two types:
- London dispersion forces which are weak attractions found between non-polar molecules.
- Dipole-Dipole attraction are the forces of attraction which exists between polar molecules. Such molecules have permanent dipoles. This implies that the positive pole of one molecule attracts the negative pole of another. This is what happens between the oxygen and sulfur molecules.
Clown fish get there food from anemone by eating by eating the algae
Answer: Option (d) is the correct answer.
Explanation:
The given data is as follows.
Tube diameter d = 10 mm = 0.01 m
Velocity of glycerol, v = 0.5 m/s
Density of glycerol () = 1240 kg/m3
Dynamic viscosity of glycerol () = 0.0813 pa.s
Reynolds number (Re) =
=
= 76.26
Therefore, according to Reynolds number we can say that flow is laminar.
Lt =
=
=
As it is known that 1 m = 1000 mm. Hence, in 0.03813 m will be equal to
= 38.13 mm
Thus, we can conclude that the transition length of glycerol is 38.13 mm.
The book lifted 10 metres. This is because it has been raised to a higher potential in a field because the field has a greater ability to do more work on it due to the larger distance. This can be seen in the equation G.P.E= m*g*h where gravitational potential energy is directly proportional to the height.
