When the clouds become too saturated with water, the water is released as precipitation in the form of:
snow |
|
ice |
|
snow or ice |
|
rain |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.
Which of the following is the correct order for types of radiation from longest to shortest wavelength?
visible light → ultraviolet light → radio waves |
|
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
|
infrared waves → microwaves → ultraviolet 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.
Which of the following states of matter exists at the highest temperature?
gas |
|
none of these |
|
solid |
|
liquid |
Solids exist at a lower temperature than liquids which exist at a lower temperature than gases.
Elements in the Periodic Table of the Elements are ordered by which of the following?
atomic mass |
|
atomic weight |
|
number of electron shells |
|
atomic number |
The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
Which of the following is the formula for work?
\(W = {\vec{F} \over \vec{d} }\) |
|
\(W = \vec{F}\vec{d}\) |
|
\(W = {F}{d}\) |
|
\(W = {{F}\over{d}}\) |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
