An ethernet cable is 3.80 m long and has a mass of 0.210 kg. A transverse pulse is produced by plucking one end of the taut cabl
Tasya [4]

Answer:

T=94.54N

Explanation:

The tension in a cable is given by:

T=\mu v^2(1)

Where \mu is the mass density of the cable and v is the speed of the cable's pulse. These values are defined as:

\mu=\frac{m}{L}(2)\\v=\frac{d}{t}

The pulse makes four trips down and back along the cable, so d=4(2L)

v=\frac{8L}{t}(3)

Replacing (2) and (3) in (1), we calculate the tension in the cable:

T=\frac{m}{L}(\frac{8L}{t})^2\\T=\frac{64mL}{t^2}\\T=\frac{64(0.21kg(3.80m))}{(0.735s)^2}\\T=94.54N

2. Using examples to describe each term, differentiate
melisa1 [442]

Answer: find the answer in the explanation

Explanation:

Average velocity is the average value of magnitude of initial velocity and final velocity.

If U = initial velocity and V = final velocity, then average velocity can be expressed as

Average velocity = ( U + V )/2

A vehicle who takes 60 minutes to cover 30 miles north and then 30 miles south and end up at the same place, has an average speed of 60 miles divided by 60 minutes, or 1 mile per minute.

Instantaneous velocity is the distance covered in a specific direction per time taken. Instantaneous velocity can be expressed as

Velocity = displacement/ time.

Uniform velocity occurs when we have a constant velocity. That is, when velocity does not change. When a vehicle travels in equal distances in equal intervals of time.
