Answer:
Explanation:
For third normal mode of vibration
l = , λ is wavelength , l is length of string .
.4 =
λ = .267 m
velocity =
T is tension and m is mass unit length
m = .5 x 10⁻³ / 40 x 10⁻²
= .00125 kg / m
Putting the values
velocity =
= 253 m /s
frequency
= velocity / λ
= 253 / .267
= 947.5 Hz .
Answer:
Atlanta is at 596.0 km from the house.
Explanation:
The distance between Atlanta and the house can be found using the following equation:
(1)
Where:
v: is the speed = 80 km/h
t: is the time = 7.45 h
By solving equation (1) for d and entering the above values we have:
Therefore, Atlanta is at 596.0 km from the house.
I hope it helps you!
