If the tube where filled with helium instead of air, how would your results change? 3. another tuning fork in the set has a frequency of 256 hz. why wasn't this one included in the procedure outlined above?

where's the following? you gotta add it to know what the choices are

explanation:

i think the answer is a and b

i wish you luck

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
