Answer:
95.3 N
Explanation:
The tension in the cable is found by the equation:
Where 
is the mass density, and 
is velocity.
First we find mass density:
--> 
is mass: 
and 
is length of the cable: 
, so:
And the velocity:
the time is 
and in that time the pulse went down and back along the cable 4 times, if one time down and back is:
2*4.15m=8.3m,
four times this path is:
4*8.3m=33.2m
thus, the velocity is:
And with this data we can now calculate the tension:
The tension is 95.3N
Answer:
No, a physical circuit is just a path connecting point and switches. It cannot be related to the transmission characteristics. It's the logical circuit which can be refers to the transmission characteristics of connection such as speed of data etc. So the answer is false.

Answer:
Explanation:
A magnet has a magnetic field around it which originates at the north pole and enters through the south pole.
In a magnet, like poles will repel each other and unlike poles will attract.
- The north pole of one magnet will repel another north pole of another magnet.
- North pole of one magnet will attract the south pole of another magnet.
- This is the law of attraction and repulsion of magnet.
Velocity is speed plus direction
Answer:
C. Experimental Probability
Explanation:
The empirical (or experimental) probability means the event that arise and depend how the event arise when the data is collected from an experiment in a more no of trials. It would be depend upon the direct observation. Here each and every observation in an experiment is known as trial
So the probability that depend upon the experiment observation is known as the experimental probability
Hence, the option c is correct
