|
kinetic |

Which of the following is the correct order for types of radiation from lowest to highest frequency?
infrared waves → microwaves → ultraviolet light |
|
visible light → ultraviolet light → radio waves |
|
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
As a cold front moves into an area, the heavier cool air __________ the lighter warm air that it is replacing.
pushes above |
|
pushes under |
|
cancels out |
|
mixes with |
A cold front is a warm-cold air boundary with the colder air replacing the warmer. As a cold front moves into an area, the heavier cool air pushes under the lighter warm air that it is replacing. The warm air becomes cooler as it rises and, if the rising air is humid enough, the water vapor it contains will condense into clouds and precipitation may fall.
Blood pressure is generally highest in which of the following?
capillaries |
|
veins |
|
heart |
|
arteries |
Arteries are thick-walled because they carry oxygenated blood at high pressure, veins are comparatively thin-walled as they carry low-pressure deoxygenated blood.
