For this case, what we must do is to rewrite these measurements in the same unit in order to compare them.
By writing the measurements in meters we have:
Therefore, physically the correct measure is:
Answer:
the length of a student's textbook most likely is:
30 centimeters
Answer:
44.4cm
Explanation:
glass has an index of refraction .n = 1.54
radii of curvature of 40 cm R1 = 40 by
radii of curvature of 600 cm R2 = 60
Now, by lens maker formula
1/f = (n - 1) (1/R1 - 1/R2)
Putting in the given values for n = 1.54 , we get f = 22.2
f = 1 / 0.0225
f = 44.4cm
so, focal length in air will be = 44.4 cm
Answer:
intensity of sound at level of microphone is 0.00139 W / m 2
sound intensity level at position of micro phone is 91.456 dB
EXPLANATION:
Given data:
power of sound P = 31 W
distance betwen microphone & speaker is 42 m
a) intensity of sound at microphone is calculated as
= 0.00139 W / m 2
b) sound intensity level at position of micro phone is
where I_o id reference sound intensity and taken as
= 91.456 dB
