I’d go with the second one. If the solute is completely dissolved, then it’s unsaturated. If it settles out, it’s saturated. If you heat up a saturated solution and it becomes unsaturated, you have a saturated solution.
R=u^2 sin2x / g
7.8=u^2 sin2*30 /10
u=9.5m/s
I = Delta p
I = Impulse
Delta p = Momentum variation
Delta p = pf - po
Pf = Final momentum
Po = Initial momentum
p = m x v
M = Mass
V = Velocity
Delta p = (m x Vf) - (m x Vo)
I = 1.2 x 10^3 x 20 - 12 x 10^2 x 18
I = 2.4 x 10^4 - 216 x 10^2
I = 2.4 x 10^4 - 2.16 x 10^4
I = 0.24 x 10^4
I = 24 x 10^2 Newtons x seconds (N x s)
Answer: The value of impulse is 24 x 10^2 Newtons x seconds (N x s).
Answer:
When the system is in thermal equilibrium
Explanation:
You know the transfer of thermal energy has ended when the temperature is uniform in the system.
Explanation:
i expected to use Stefan's law of heat exchange but the value you gave aren't conclusive.
I should say that the temperature of the star should be close to that of the sun because of the similarity in the intensity curves
