Answer:
t = 0.657 s
Explanation:
First, let's use the appropiate equations to solve this:
V = √T/u
This expression gives us a relation between speed of a disturbance and the properties of the material, in this case, the rope.
Where:
V: Speed of the disturbance
T: Tension of the rope
u: linear density of the rope.
The density of the rope can be calculated using the following expression:
u = M/L
Where:
M: mass of the rope
L: Length of the rope.
We already have the mass and length, which is the distance of the rope with the supports. Replacing the data we have:
u = 2.31 / 10.4 = 0.222 kg/m
Now, replacing in the first equation:
V = √55.7/0.222 = √250.9
V = 15.84 m/s
Finally the time can be calculated with the following expression:
V = L/t ----> t = L/V
Replacing:
t = 10.4 / 15.84
t = 0.657 s
Answer:

Answer:
Essentially, your thumb is the main piece of your body that has saddle joints. The bones in your seats joint are in charge of moving forward and backward, side to side.
When all is said in done, the piece of the thumb joint that is subjected to extreme anxiety is that known as CMC joint or carpometacarpal joint. This joint is fundamentally shaped by the metacarpal bone and it explains with the trapezium bone of the wrist.
Explanation:
<h3><u>Answer;</u></h3>
= 21600 Joules or 21.6 Kilo joules
<h3><u>Explanation;</u></h3>
Electrical energy is given by the formula = VIt ;
where V is the voltage in volts, I is the current in Amperes, and t is time in seconds.
Voltage = 120 volts
Current = 3 amperes
Time = 60 seconds or 1 minute
Therefore;
Electrical energy = 120 × 3 × 60
<u> = 21600 Joules or 21.6 Kilo joules</u>
No they do not there not humans
