This process of physically separating a single phase mixture into several components would be termed simple distillation, I believe.
As it is mentioned that one is separating them based on their different boiling points.
Complete Question:
Two small objects each with a net charge of Q (where Q is a positive number) exert a force of magnitude "F" on each other. We
replace one of the objects with another whose net charge is 4Q. The original magnitude of the force on the Q charge was "F"; what is the magnitude of the force on the Q charge now?
Answer:
4 F₀
Explanation:
Assuming that we can treat to both objects as point charges, we can find the force "F" that one charge exerts upon the other applying Coulomb´s law, as follows:
F₀ = K*Q₀² / r₁₂²
If we replace one of the charges by one with a 4Q₀ charge, the new value of F will be as follows:
F₁ = K*Q₀*4Q₀ / r₁₂² =( K*Q₀² / r₁₂²)* 4 = 4* F₀
This value is reasonable, as the electrostatic force is a linear - type one, so it is possible to use the superposition principle (we can get the force exerted by one charge on another without considering the ones due to another charges)
Answer:
v = -0.45 m/s
Explanation:
Assuming the canoe was initially at rest with momentum L = 0
and that the dog's velocity is in the positive direction
conservation of momentum
0 = 15(1.2) + 40v
v = -0.45 m/s
Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
as we know that angular acceleration of the wheel is given as
now the radius of the wheel is given as
R = 3.21 cm
so the tangential acceleration is given as
Part b)
frequency of the wheel at maximum speed is given as
now we know that
now radial acceleration is given as
Part c)
total angular displacement of the point on rim is given as
here we know that
now angular displacement will be
now the distance moved by the point on the rim is given as
Answer:
Graph C
Explanation:
This is the answer because it is the only one that shows the vehicle accelerate to a constant speed before stopping and slowing down.
