How do repeater stations improve the quality of a broadcast?

1 answer:

3 0

They pick up broadcast signals, amplify them, then send them out.
This is needed due to the radio waves traveling in a ripple pattern; they degrade over time.

You need to get to class, which is 282 meters away. You can only walk in the hallway at about 2.0 m/s (if you go any faster, you

worty [1.4K]

Answer:

Time, t = 141 seconds

Explanation:

Given that,

Distance between the class and the person, d = 282 m

Speed of the person, v = 2 m/s

We need to find the time taken by the person to get to your class. Let the time taken is t. The speed of the person is given by :

$v=\dfrac{d}{t}$

$t=\dfrac{d}{v}$

$t=\dfrac{282\ m}{2\ m/s}$

t = 141 seconds

So, the time taken by the person to get to your class is 141 seconds. Hence, this is the required solution.

A stone is dropped from the edge of a roof, and hits the ground with a velocity of -180 feet per second. How high (in feet) is t

Neko [114]

Answer:

d = 506.25 ft

Explanation:

As we know by kinematics that

$v_f^2 - v_i^2 = 2 a d$

here we know that initially the stone is dropped from rest from the edge of the roof

so here initial speed will be zero

now we have

$v_i = 0$

also the acceleration of the stone is due to gravity which is given as

$g = 32 ft/s^2$

now we have

$v_f = 180 ft/s$

so from above equation

$180^2 - 0 = 2(32)d$

$d = 506.25 ft$
