Answer:
A) 8.03Hz
Explanation:
f = V/λ
Where wavelength( λ )= 30m
Speed (V) =241m/S
f= 241/30=8.03Hz
Not if both speeds are in the same units.
However, if the 254 is 'centimeters per time' and the 100 is 'inches per time',
then the speeds are equal.
Thank you for the message my friend, yoU have a good day as well :)
Potential Energy= 24m * 14kg * 9.8N/kg = 3292.8J
