Calculate For the reaction described in question 30, the concen-trotion of CH 3 CHO is found to increase from 0.0300mol / l to 0.0500mol / L in 42.5 seconds. Express the average rate of the reac-tion in mol CH3CHO produced/L. s.

According to newtons universal law of gravitation, which would change the parh of the ball so it traces out widest curved path possible?

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.
