Answer:
T = 243.80 N
Explanation:
In order to calculate the tension T in each of the cables, you take into account the Newton second law for the vertical component of the forces involved.
(1)
where you have used the fact that both cables have the same tension T, and they make the same angle with the horizontal.
W is the weigh of the loudspeaker and has the folowing values:
Next, you can calculate the angle θ by using the information about the length of the cables and the distance from the ceiling to the loudspeaker:
Finally, you solve the equation (1) for T, and then you replace the values of the other parameters:
The tension in each cable is 243.80N
Answer:
1.7 × 10^11 Pa
Explanation:
Please see the attachments below
Net force = mass × acceleration
F= ma
a = F/M
a = 6f/2m
a= {3f/m} ms-²
Answer:
The value is
Explanation:
The time taken for the column to take a step mathematically represented as
100 steps => 1 minutes => 60 seconds
1 step => t
=>
Generally the length of the column is mathematically represented as
substituting 343 m/s for v we have
=>
