Answer:

With Boyle's law we have that for a constant temperature and gas quantity the pressure of a gas multiplied by its volume is also constant: This means that under the same temperature, two gases with equal quantity of molecules and equal volume must also have the same pressure, as well as that two gases with equal quantity and pressure must have the same volume.

A small rock is thrown vertically upward with a speed of 22.0 m/s from the edge of the roof of a 30.0-m-tall building. The rock

Answer:

a) $v=32.74\frac{m}{s}$ .

b) $t=\frac{v-v_0}{g} =5.58s$ .

Explanation:

a) What is the speed of the rock just before it hits the street?

From Kinematics we have $v^2= v_0^2+2a(y_f-y_i)$ .

If we take the top of the roof as the position $y_0=0m$ , then

$y_f=-30m$ and we have (also, $a=g=-9.8\frac{m}{s^2}$ ) :

$v^2= v_0^2+ 2ay_f$ ⇒ $v= \sqrt{v_0^2+ 2ay_f}$

⇒ $v=32.74\frac{m}{s}$ .

b) How much time elapses from when the rock is thrown until it hits the street?

From Kinematics we have $v(t)=v_0+at=v_0+gt$

When the rock touches the ground:

$v=-32.74\frac{m}{s}$

With a minus sign to indicate the vector velocity points down.

$t=\frac{v-v_0}{g} =5.58s$

(remember that $g=-9.8\frac{m}{s^2}$ )

Which statement describes a digital signal?

hoa [83]

Answer:

"It is made of numbers" describes the digital signal.

Explanation:

The digital signal are the electrical signal which is translated into the pattern of bits. The digital signal are always discrete value in every sampling point. The conversion of the programming into the stream or the binary sequence like 0s and 1s. The digital signals never gets weaken over distance but the analog signal gets weakened or impair at distance. The digital signals are consists of one or two value, Timing graph are square waves.
