To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
The rows of the Periodic Table of the Elements are called:
shells |
|
groups |
|
families |
|
periods |
The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.
In the water cycle, infiltration is most closely related to:
water table |
|
runoff |
|
rivers |
|
oceans |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.

Which of the following is the correct order for types of radiation from longest to shortest wavelength?
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
|
visible light → ultraviolet light → radio waves |
|
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.
