How star properties affect star formation? provided following are the spectral types of four different main-sequence stars. rank the stars based on the strength of the radiation pressure that pushes outward as they are forming, from highest pressure to lowest pressure. a) o9.b) a5.c) g2.d) m6.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

thermal energy is the answer

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
