Answer:

it decreases in size

Explanation:

The reason why this happens is simply just condensation. unlike when water is boiling, that is evaporating

A ball tossed vertically upward from the ground next to a building passes the bottom of a window 1.8 s after being tossed and pa
VLD [36.1K]

The ball takes 0.2 sec to travel the height of the window, which is 2 m.

 Then the speed of the ball at that time was

v = \frac{d}{t}

v = \frac{2}{0.20}

v = 10\ \frac{m}{s}

We know that:

v = v_0 -gt

Where v_0 is the initial velocity.

So:

10 = v_0 -9.8(2)

10 + 9.8(2) = v_0

v_0 = 29.6\ m / s

Then we have the equation for the position as a function of time.

r = r_0 + v_0t - \frac{1}{2}gt^2

Where

r_0 = initial position

r = position as a function of time

v_0 = initial velocity

g = acceleration of gravity

t = time.

If the ball is thrown from the ground then:

r_0 = 0 m

We want to find now the distance between the window and the ground.

When the ball reaches the bottom of the window t = 1.8s

So:

r = 0 + 29.6(1.8) - 0.5(9.8)(1.8)^2

r = 37,404 m

The window is 37,404 m high

Finally, to know how high the ball rises we must know at what moment the vertical velocity of the ball is zero.

v = v_0 -gt\\\\0 = v_0 -gt\\\\gt = v_0\\\\t = \frac{29.6}{9.8}

t = 3.02\ s

Now we replace t in the position equation

r = 0 + 29.6(3.02) -0.5(9.8)(3.02)^2

r = 44.70\ m

The ball reaches up to 44.70 m in height.

A solid is 5 cm tall, 3 cm wide, and 2 cm thick. It has a mass of 129 g. What is its<br> density?
rjkz [21]

Answer:

4.3 g/cm³ or 4.3g/cc

Explanation:

Volume(V) = Height × Length × Width

= 5cm × 3cm × 2cm

= 30cm³

Mass(m) = 129gram

So,

Density = m/V

= 129g/30cm³

= 4.3g/cc or 4.3g/cm³
