Final answer:
The length of a soccer field, given as 120 meters, converts to approximately 393.72 feet when using the conversion factor of 1 meter being equivalent to 3.281 feet.
Step-by-step explanation:
It appears that the original question regarding the cheerleaders making megaphones was replaced with several unrelated physics problems. I will provide an answer to one of the listed physics questions.
Conversion of Length of a Soccer Field to Feet
The length of a soccer field is given as 120 meters. To convert this length to feet, we use the conversion factor that 1 meter is equivalent to approximately 3.281 feet. Therefore, the length of the soccer field in feet is calculated as follows:
Length in feet = Length in meters × conversion factor = 120 m × 3.281 ft/m
Length in feet = 393.72 ft
