Question

The centripetal acceleration will be lowest at (Hint: Fan:400rpm with blade length of 60 cm, Earth: one rotation in 24hr, Radius of earth 6378 km, Jupiter: one rotation in 10hr, Radius of Jupiter is 69911 km​

Answer 1

Step-by-step explanation:

Time period of earth's rotation is ,T=24h=86400 s

Angular velocity, ω=2π/T

Radius of earth, r=6378km=637800m

Now, centripetal acceleration ω2r=T (2π)

2r=0.034m/s

2 =3.4s2cm

Answer 2

Answer:

blade of the celling fan
