Answer 1

PLEASE GIVE IT A THUMBS UP !!!

THANK YOU !!!

(a)

f = 1/2 sqrt ( g/L)

f = 1/2 sqrt ( 9.8 / 2.2)

f = 0.336 Hz

________________________

(b)

apparent acceleration is g + a

so,

f = 1/2 sqrt ( g + a / L)

f = 1/2 sqrt ( 11 / 2.2)

f = 0.355 Hz

(c)

in free fall, tension is zero,

so,

f = 0 Hz
