3 0

Answer:

Unsaturated Solution: Less amount of salt in water, clear solution, no precipitation. Saturated Solution: The maximum amount of salt is dissolved in water, Colour of the solution slightly changes, but no precipitation. Supersaturated Solution: More salt is dissolved in water, Cloudy solution, precipitation is visible.

student built a simple heat engine that could lift masses. If the heat engine takes in 300 J of heat and loses 50 J to the envir

k0ka [10]

Answer:

So it will lift the mass by h = 17 m

Explanation:

As per energy conservation we know that

$Q_1 = W + Q_2$

here we know that

$Q_1 = 300 J$

$Q_2 = 50 J$

now we have

$W = 300 - 50$

$W = 250 J$

so work done by the engine is 250 J

now we have

$W = mgh$

$250 = 1.5 \times 9.81 \times h$

$h = 17 m$

Describe how varying the incline plane angle Affects the force

Greeley [361]

Answer: the force increases as the angle increases

Explanation:

If we assume the incline plane is frictionless, the only force acting on an object on the incline plane is the force of gravity:

$F=mg$

where m is the mass and g the acceleration due to gravity.

However, the actual force that makes the object sliding down along the incline is not the gravity itself, but the component of the force of gravity parallel to the surface of the incline, which is given by

$F_p = mg sin \theta$

where $\theta$ is the angle of the incline.

Therefore, we see that as the angle of the incline increases, the force on the object increases.
