Answer:
Higher percentage of runoff water is absorbed by the vegetation whereas 100 % of water runoff on the roofed area.
Explanation:
Higher percentage of runoff water is absorbed by the vegetation and very little amount of runoff water is received on the end of vegetative cover while on the other hand, 100 percent of precipitation water runoff on the surface of roofed or paved area because no water is absorbed by the roof due to its solid surface. The percentage of runoff depends on the factors such as rainfall intensity, slope, soil water storage capacity, and infiltration rate.
From my experience, I would say it is true.
Answer:
Given:
radius of the coil, R = 6 cm = 0.06 m
current in the coil, I = 2.65 A
Magnetic field at the center, B = 
Solution:
To find the number of turns, N, we use the given formula:
Therefore,
N = 22.74 = 23 turns (approx)
Answer:
a) μ = [kg / m s]
b) D = m²/s
Explanation:
Viscosity is equivalent to a friction force that opposes the movement of fluids, it is defined by the relation
Shear stress = μ speed gradient
Fr/A = μ v₀ / h
Where Fr is the shear force, A the area, h the height and v₀ the velocity of the fluid layer
μ = [kg / m s]
The diffusion coefficient characterizes the ability of a material to move in a given solvent, depending on the size of the solute, the viscosity of the solvent, temperature
J = - D dΘ / dx
J is the broadcast glare
D = [m² / s]
