Answer:
Inverse multiplexer or demultiplexer
Explanation:
An inverse multiplexer or demultiplexer behaves in an opposite way to the multiplexer. It collects data from a single source and breaks it down into several smaller outputs.
<em>A transponder performs the function of transmitting and receiving data in digital communication.</em>
<em>A multiplexer collects data from several analog or digital input signals and forwards them to a single output line</em>
<em>codec is used to decode and decode digital data streams</em>
<em>intelligent terminals are simply terminals that have processing power just like a smart keyboard.</em>
Answer:
Explanation:
According to the <u>Third Kepler’s Law</u> of Planetary motion:
(1)
Where;:
is the period of the satellite
is the Gravitational Constant and its value is
is the mass of the Earth
is the semimajor axis of the orbit the satllite describes around the Earth (as we know it is a circular orbit, the semimajor axis is equal to the radius of the orbit).
On the other hand, the orbital velocity is given by:
(2)
Now, from (1) we can find
, in order to substitute this value in (2):
(3)
(4)
(5)
Substituting (5) in (2):
(6)
(7) This is the speed at which the satellite travels
The car A and car B are travelling at different speeds. The car that has a greater acceleration is car B.
<h3>What is acceleration?</h3>
Acceleration is defined as the rate change of velocity with time.
acceleration a = (Δv) / (Δt)
Car A is traveling with a constant velocity of 18 [m/s]. The initial and final velocity is same. So, the acceleration is given by
a = (18 -18)/ t
a = 0 m/s²
Car B speeds up from 0 [m/s] to 10 [m/s] in 4 seconds. The acceleration is
a = (10 -0)/ 4
a = 2.5 m/s²
Thus, the car B has greater acceleration.

Answer: did you get the answers?
Explanation:
In order to calculate the time taken by the snowball to reach the highest point in its journey, we need to consider the variables along the y-direction.
Let us list out what we know from the question so that we can decide on the equation to be used.
We know that Initial Y Velocity = 8.4 m/s
Acceleration in the Y direction = -9.8 m/, since the acceleration due to gravity points in the downward direction.
Final Y Velocity = 0 because at the highest point in its path, an object comes to rest momentarily before falling down.
Time taken t = ?
From the list above, it is easy to see that the equation that best suits our purpose here is
Plugging in the numbers, we get 0 = 8.4 - (9.8)t
Solving for t, we get t = 0.857 s
Therefore, the snowball takes 0.86 seconds to reach its highest point.
