Which best describes what happens to sunlight after it passes through the keyhole of a door? a) it converges until one particular shadow region b) it spreads out into multiple shadow regions c) it bends back toward the door d) it scatters back toward the door

How is that?

Diffraction happens when a wave (mechanical or electromagnetic wave) meets an obstacle or a slit .

When this occurs, the wave bends around the corners of the obstacle or passes through the opening of the slit that acts as an obstacle, forming multiple patterns with the shape of the aperture of the slit.

Note that the principal condition for the occurrence of this phenomena is that the obstacle must be comparable in size (similar size) to the size of the wavelength.

Now, if we assume the sunlight as an electromagnetic wave that passes through the keyhole of a door (obstacle), this light will scatter and multiple shadow regions with the shape of the keyhole will be formed.

Therefore, the answer is B:

muscle endurance

explanation:

i can do 50 in a row ( but i get so tired after that)

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.
