Y: Radio
Z: Gamma
because gamma has a higher frequency then radio, therefore the higher the frequency the shorter the wavelength
It looks correct, but that graph only shows position and time?
answer - d
set up equation
the velocity can be found through the change in kinetic energy
due to the conversation of energy, the change in kinetic energy is the same as the change in potential energy when the height is changed
ΔK =
ΔU = mgΔh
ΔK = ΔU
= mgΔh
= 2gΔh
v =
values
g = 9.8
Δh = 42 - 4.2 = 37.8 m
plug in values
v =
v =
v = 27.2
answer choice D
Answer: (c) Context Effect
Explanation: Context Effect is an aspect of cognitive psychology which describes how environmental factors afects a person's perception of stimuli. It is known to occur at all scales at which words may be viewed. It is supported by constructive perception, the effect of a context perception is known to be part of a top-down design, the view of the moon through a narrow tube which has affected the perception of the viewer who now see the moon as shrinking in size is a context perception.
