Answer:
Intensity at 45 cm will be 0.2283 volt
Explanation:
We have given that intensity of signal measured by the detector is 0.74 volt at a distance of 25 cm
We know that intensity of signal is given by 
, here s is strength of light and r is distance
So 
In second case
Intensity is given by
So 
, to hit nails into a piece of wood or a wall, or to break things into pieces.
Answer:
if your glasses are polarized, you can see the fish in the water. also im pretty sure its d
Explanation:
To answer the problem we would be using this formula which isE = hc/L where E is the energy, h is Planck's constant, c is the speed of light and L is the wavelength
L = hc/E = 4.136×10−15 eV·s (2.998x10^8 m/s)/10^4 eV
= 1.240x10^-10 m
= 1.240x10^-1 nm
