Answer:
the force exerted on the dipole = 0.11 N
Explanation:
Using F = (KQq/r^2) sin ∅
the distance of dipole to the line charge will be 30 cm, hence 1 st charge on the dipole -10 micro C is 29 cm and that to + 10 micro C is 31 cm (2 cm apart).
0.91 N with -ve charge and 0.80 to +ve charge. The difference is the force on the dipole i.e 0.11 N
Answer:
9.3 hours to travel 600 km.
Explanation:
The average geese speed is around 40 mph or 64.3 km/h, but in good weather and wind conditions this speed can go up to 70 mph or 112 km/h
Considering the formula:
were x=space, v=speed and t= time. Clearing the equation, to find the hours of flight:
So, the geese will take 9.3 hours to travel 600 km at their average speed of 64.3km/h.
Answer:
Convection
Convection transfers heat energy through gases and liquids. As air is heated, the particles gain heat energy allowing them to move faster and further apart, carrying the heat energy with them. Warm air is less dense than cold air and will rise.
Chemical energy is the potential of a chemical substance to undergo a transformation through a chemical reaction to transform other chemical substances. Examples include batteries, food, gasoline, and etc.
Answer:
Hydrogen bonding
Ionic bonding
Non- induced dipole forces
Ion dipole forces
Van-der wall forces
Explanation:
Intermolecular forces are the forces which operates at molecular level they may be attractive or repulsive in nature. But the given question ask only about attractive molecular forces. These are of basically five types:-
1. Hydrogen bonding- It is the force of attraction between hydrogen atom and an electro-negative atom.
2 .Ionic bonding- It is the force of attraction between cationic and anionic pair.
3.Non - Induced dipole forces- It is the dipole- dipole interaction between permanent electromagnetic materials.
4.Ion-dipole forces- These bonds are stronger than hydrogen bond and also stronger than dipole-dipole bond.
Van-der walls forces- It is the force of attraction between uncharged molecules.
