A marble is rolling at a speed of 3.31 m/s  Falls of the end of the table that is 91.2 cm tall.  how long will the marvel be in the air?

d 0.431 seconds

Explanation:

= Height of the table = 91.2 cm

a = g = Acceleration due to gravity =

= Initial velocity in y axis = 0

y = Height of floor = 0

t = Time taken to fall to the floor

The marble will be in the air for 0.431 seconds

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

c because the action was the roller coaster reaches bottom of hill (action) reaction would be blood tends to drain away from head
