How can the rate of evaporation of a liquid be increased?
2 answers:
Answer:
Temperature: The greater the temperature of the liquid and its surroundings, the faster the rate of evaporation.The Surface area occupied by the liquid: Since evaporation is a surface phenomenon, the greater the surface area occupied by the liquid, the quicker it undergoes evaporation.

<h2>The current required winding isExplanation:
We can use the expression B=μ₀*n*I-------1 for the magnetic field that enters a coil and
n= N/L (number of turns per unit length)
Given data
The number of turns n= 1200 turns
length L= 0.42 m
magnetic field B= 1*10^-4 T
μ₀=
Applying the equation B=μ₀*n*I
I= B/μ₀*n
I= B*L/μ₀*n
Answer:
v = 0.33 m/s
Explanation:
The final velocity of the skier and boat can be calculated by conservation of the lineal momentum:
<u>Where:</u>
m1: is the mass of the water skier = 62.0 kg
m2: is the mass of the boat = 775 kg
v1i: is the initial velocity of the water skier = 4.50 m/s
v1f: is the final velocity of the water skier = ?
v2i: is the initial velocity of the boat = 0
v2f: is the final velocity of the boat = ?
Since the final velocity of the skier is the same that the final velocity of the boat, we have:
Therefore, the final velocity of the skier and boat is 0.33 m/s.
