Answer: C ) 75 kilometers
Explanation: 30 + 45 = 75
Answer: D.ultraviolet rays, visible light, infrared radiation, microwaves.
Explanation:
Shorter wavelength means higher frequency and higher energy.
Thus, the correct sequence of electromagnetic waves from shorter wavelength to longer wavelength is:
D.ultraviolet rays, visible light, infrared radiation, microwaves.
<u>Ultraviolet rays have shorter wavelength (about 380 nm) and high energy. </u>
<u>Visible light has wavelength: 380 nm to 700 nm</u>
<u>Infrared wavelength: 700 nm to 1 mm</u>
<u>Microwave wavelength: 1 mm to 1 m</u>
D=-5m
a(gravity)=-9.8m/s^2
vi= 0m/s
t=?
use equation d=vi*t+0.5a*t^2
because vi=0, you can cross out vi*t because anything multiplied by 0= 0
rearrange the equation to say t^2=d/0.5a
t^2= -5/-4.9
t^2=1.02
find the square root...
final answer: t=1s
