Answer:
T= 5.18N
Explanation:
u = mass of chord / length of chord
u = 0.49/ 7.3
u = 0.067 kg/m
Velocity of sound waves (v) =length of chord / time taken for wave to travel
v = 7.3 / 0.83 = 8.795m/s
Tension is calculated below using the formula
T = v² * u
T = (8.795)² x 0.067
T= 5.18N
Explanation:
Liquids also exert pressure in all directions on the walls of the container they are stored in. We see water coming out from leaking pipes and taps. ... Gases (Air) also exert pressure in all directions

Answer:
The final graph
Explanation:
The graph that curves downwards is negative acceleration. While the position decreases the slop increases.
The correct answer is option A. i.e. An important thing to consider when responding to a driver in front of you that stops suddenly is: the mental state of the other driver.
Our talk or discussion can disrturb the balance of the driver or he can get distracted. So, we must try not to speak much while the driver is driving because by doing this we are putting the life of ourselves in danger. Any distrcaction of driver can cause accident.
