Question

Ch. Ex. 60 -A biologist is studying plant growth and wants to simulate a gravitational field twice as strong as 1 out of 7 attempts Assistance A biologist is studying plant growth and wants to simulate a gravitational field stronger than the Earth's. She places the plants on a horizontal rotating table in her laboratory (on Check My Work Earth) at a distance of 43.2 cm from the axis of rotation. What angular speed will give the plants an effective gravitational field, &eff;, of magnitude 2.80g ? [Hint: Remember to account for Earth's gravitational field as well as the artificial gravity when finding theShow Me effective gravitational field.] View Hint View Question Guided Solution Practice This Question Print Question Help Report a Problem rad/s

Explanation / Answer

2.80g = ^2*r
= 2.80*g/r = 27.44/0.432 = 7.9 rad/sec

That is the angular speed required for the horizontal table to reqch effective acceleration as 2.80g
