Okay so you would do 90 / 3 which would be feet / three=yards and then minus it. because 3 feet are in 1 yard
The correct option is "d".
Given that L = 0.8T²
length of pendulum = 30ft
L= 0.8T²
30 = 0.8T²
T² = 30 / 0.8
T² = 37.5
T = √37.5 = 6.1 seconds
<span>So, 6.1 is the closest to the period in seconds for a pendulum that is 30 ft long.</span>
meee lol you can talk to me
Answer:
Step-by-step explanation:
That would be 8 x 3. It would help because 24/8 = 3.
