The formula for momentum is p = mv, where p is momentum, m is mass, and v is velocity.
To solve for p, plug in 750 kg for mass and 30 m/s for velocity. • is a multiplication symbol
p = mv
p = 750kg • 30m/s
p = 22500 kg•m/s
I think you need more information like the force of gravity and the force of the three people. Once you combine the two, however, you should get the net force.
Frequency division multiplexing operates by dividing the signal into different frequencies
<u>Explanation:</u>
The technique that is used in the networking is the Frequency Division Multiplexing. using this technique, the existing bandwidths can be partitioned into different frequency bandwidths. These are not interrupting with each other. Each bandwidth can be used for carrying signals individually.
Using this technique many users can share a particular communication medium and they will not be interrupted with each other's communication.Hence this technique can also be termed as Frequency Division Multiple Access.
Your answer is B.
The relationship between medium temperature and speed of sound is a direct relationship: when one factor increases, the other increases as is shown in graph B. The British would choose the the time of day which would give the lowest speed of sound, because this would be easiest to break. Graph B shows that the lowest speed of sound would occur with the lowest air temperature - in the morning.
