Answer:
T=1022.42 N
Explanation:
Given that
l = 32 cm ,μ = 1.5 g/cm
L =2 m ,V= 344 m/s
The pipe is closed so n= 3 ,for first over tone
f= 129 Hz
The tension in the string given as
T = f²(4l²) μ
Now by putting the values
T = f²(4l²) μ
T = 129² x (4 x 0.32²) x 1.5 x 10⁻³ x 100
T=1022.42 N
Answer:
D
Explanation:
At noon on the summer solstice. The sun dagger was used to observe astrological readings in the ancient time
Answer:
A.Consider and evaluate the consequences of each choice
Explanation:
As you enter the decision-making proccess you would have to see the different options that you have, after this you just have to consider and evaluate the consequences of the different options that you have, in this phase you have to weight the consequences and what it would take to make those decisions.
Answer:
the minimum thickness (in nm) t = 102.5 nm
Explanation:
t = thickness of the film
n = index of refraction = 1.61
m = order = 1
∝ = wavelength = 330 x 10-9 m
so we have the formula
2nt = m∝
2 (1.61) t = (1) (330 x 10-9)
then...
t = 1.025 x 10-7 m
converting...
t = 102.5 nm
The potential energy is directly proportional to the height.
If you double the height you double the potential energy.
