Yes they are equivalent because 7x5=35 and 8x x 5=48x
Answer:
12 c 13 d
Explanation:
12
t = 2(6)-3(3) = 12 - 9 = 3
13
q=(2(3)-2)/4 = (6-2)/4 = 4/4 = 1
Solve for the time it will take to complete a revolution. That is,
0.510 s / 440 revolutions = 51/44000 s
The frequency in Hertz is the reciprocal of this value thus the frequency is approximately equal to 862.75 Hz.
Angular velocity expressed in radians/second
(440 rev / 0.510 s) x (2π rad / 1 rev) = 5420.787 rad/s
The period is the reciprocal of frequency which is approximately equal to 1.16x10^-3 s.
Answer:
Thickness = 103.38 nm
Explanation:
Given that:
The refractive index of the thin soap bubble = 1.33
The wavelength of the light = 550 nm
The minimum thickness that produces a bright fringe can be calculated by using the formula shown below as:
Where, n is the refractive index of the thin soap bubble = 1.33
is the wavelength
So, thickness is:
<u>Thickness = 103.38 nm</u>
