Step-by-step explanation:
2.65-2.30 is 0.35
0.35/2.65 is 0.132
0.132 X 100 is 13.2% decrease
It would be 46.34 percent.
Answer:
The value of the damping coefficient γ is (6/19)√29, which is approximately 1.70058.
Step-by-step explanation:
Given that a certain vibrating system satisfies the equation
u'' + γu' + u = 0
We wish to find the value of the damping coefficient γ for which the quasi period of the damped motion is 90% greater than the period of the corresponding undamped motion.
The period of the undamped motion T is 2π
The quasi period T_d is (4π)/√(4 - γ²)
Since the quasi period is 90% greater than the period of the undamped motion, we have
T_d = 1.9T
So that we can finally obtain
γ as 1.70058.

Answer:
x=67°
Step-by-step explanation:
Sum of all angles is 180°
36°+77°+x=180°
113°+x=180°
x=180°-113°
x=67°
Bro this is right answer plzzz mark me as brainliest★
