Answer:
for given question is 2.79 and 
is 0.52
{i- vant hoff’s constant ; Kb- constant ; m molarity }
M = no. of moles of the solute present in one kg of solution
Let the weight of amount of solute be “w” and its molecular mass be “M”
Let the mass of the solvent in the given question be “x”
The majority of wind turbines consist of three blades mounted to a tower made from tubular steel. There are less common varieties with two blades, or with concrete or steel lattice towers. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes.
Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller. So therefore your answer would be A.

Which of the following is not an example of a mass movement?
to. a. Ground slides b) acid rain c. mud flow d. drop
Answer:
b) acid rain
Explanation:
Acid rain is not an example or a type of mass movement.
Mass movement or mass wasting is the movement of rocks, soils and other debris downslope under the influence of gravity.
Water, slope and gravity are triggers of mass movement.
- Acid rain is a not a form of mass movement
- It occurs with some certain gases mixes rain water to produce an acidic precipitation.
- When the water falls to the each surface, it causes problems to the ecosystem and can also corrode building materials.
