The auditory nerve carries an electrical signal to the brain, which turns it into a sound that we recognize and understand.
Answer:
29.16 J
Explanation:
From Hook's law,
W = 1/2(ke²)..................... Equation 1
Where W = work done, k = Spring constant, e = extension.
Given: W = 9 J, e = 0.5 m.
Substitute into equation 1
9 = 1/2(k×0.5²)
Solve for k
k = 18/0.5²
k = 72 N/m.
The work done required to stretch the spring by additional 0.4 m is
W = 1/2(72)(0.4+0.5)²
W = 36(0.9²)
W = 29.16 J.
Answer:
It does not hit the students face because the speed of the balloon slows down as energy is lost through thermal.
Explanation:
Answer:
There will be a phase change at the first interface and no phase change at the second interface:
If the film is 1/4 wavelength thick this restriction will hold
The wavelength of the light in oil is 545 nm / 1.45 = 376 nm
376 nm / 4 = 94 nm
"D" is correct
