Domestic cats have vertical pupils. Imagine a cat is observing two small birds sitting side-by-side on a telephone wire. If the slit width of the cat's pupils is a = 0.550 mm and the average wavelength of the ambient light is λ = 519 nm, what is the angular resolution (in rad) for the two birds?

To solve this problem we will apply the concepts related to angular resolution based on wavelength and the slit width at this case of the cat's pupils. This relationship is given as,

Here,

=  Wavelength

a = Slit width

Therefore the angular resolution is

im sorry i dont know

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
