pentagon [3]

The change of state as depicted by the model is condensation.

<h3>What is Condensation?</h3>

The process by which the water vapors get converted into liquid droplets to get settled on a cold surface is known as condensation.

As per the given problem, the cylinder in the left has the balls evenly spaced throughout and the right cylinder has the balls in the form of layers at its bottom.

So, this clearly reflects that the comparing both the balls in both cylinders, the right cylinder consists of the balls undergone through the process of condensation.

This is because,

During condensation, the vapor molecules get converted into liquid.

And in the left cylinder, the balls evenly spaced have more intermolecular distance which designates the gaseous molecules.

While in the right cylinder, the layered form of gas shows that the conversion occurred to some state of molecules, having less intermolecular space.

And liquid has less intermolecular space than gas.

Thus, we can conclude that the change of state as depicted by the model is condensation.

A ball is thrown downward at 12 m/s from a windowsill 35 m above the ground. At the same time, another ball is thrown upward at

wariber [46]

Answer:

The second ball lands 1.5 s after the first ball.

Explanation:

Given;

initial velocity of the ball, u = 12 m/s

height of fall, h = 35 m

initial velocity of the second, v = 12 m/s

Time taken for the first ball to land;

$t = \sqrt{\frac{2h}{g} }\\\\t =\sqrt{ \frac{2*35}{9.8}}\\\\t = 2.67 \ s$

determine the maximum height reached by the second ball;

v² = u² -2gh

at maximum height, the final velocity, v = 0

0 = 12² - (2 x 9.8)h

19.6h = 144

h = 144 / 19.6

h = 7.35 m

time to reach this height;

$t_1 = \sqrt{\frac{2h}{g} }\\\\t_1 = \sqrt{\frac{2*7.35}{9.8}}\\\\t_1 = 1.23 \ s$

Total height above the ground to be traveled by the second ball is given as;

= 7.35 m + 35m

= 42.35 m

Time taken for the second ball to fall from this height;

$t_2 = \sqrt{\frac{2h}{g} }\\\\t_2 = \sqrt{\frac{2*42.35}{9.8} }\\\\t_2 = 2.94 \ s$

total time spent in air by the second ball;

T = t₁ + t₂

T = 1.23 s + 2.94 s

T = 4.17 s

Time taken for the second ball to land after the first ball is given by;

t = 4.17 s - 2.67 s

T = 1.5 s

Therefore, the second ball lands 1.5 s after the first ball.

andriy [413]

Answer:

Weight, W = 125 N

Explanation:

Pressure, P = 5 Pa

Area, A = 25 m²

We need to find how much must a man weigh (force) if the pressure he exerts while standing on one foot which has an area of 25 m² exerts a pressure of 5 Pa. So,

Pressure = force/area

So,

$F=P\times A\\\\F=5\times 25\\F=125\ N$

So, the weight of the man is 125 N.
