A ball is launched straight up with initial speed of 30.0 m/s. What is the ball's velocity when it comes back to its original po
Zanzabum

Answer:

We could get the time taken by the ball to return back to earth, using the formula:

s = u t + ½ a t², where

s = displacement of the body moving with initial velocity u, acceleration 'a' in time t.

In the present case s=0 (as the ball returns back to starting time)

u= 30 m/s; a = -10 m/s² ( negative sign as a is in opposite direction to u); t=?

0 = 30 t - ½ ×10 ×t²; ==> 5 t = 30, t= 6 second.

So ball will return back after 6 second after being thrown up.

Karl listed the steps involved when information is sent from transmitters to receivers. 1 - A signal is produced. 2 - Radio wave
anastassius [24]
The step missing is after the number 4. Because, after the antenna captures de modultates waves, it has to be demodulated in order to be able to the signal be heard, seen or used.

So, the answer is that waves are demodulated and it before the signal is heard, seen or used.
