The pupil of a cat's eye narrows to a vertical slit of width 0.540 mm in daylight. Assume the average wavelength of the light is 471 nm. What is the angular resolution for horizontally separated mice

Resolution of the light will be equal to

Explanation:

We have given a pupil of cat  width of the slit d = 0.540 mm =

Average wavelength of the light

We have to find the angular resolution for horizontally separated mice  

Angular resolution is given by

So resolution of the light will be equal to

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m
