i need help instantly
A drop of water on a kitchen counter evaporates in a matter of minutes. However, only a relatively small fraction of the molecules in the drop move rapidly enough to escape through the drop's surface...
An object is being swung in a circular path at the end of a 30 meter cable. The ball completes 120 revolutions each minute (120 RPM). What is the centripetal acceleration (in m/s^2)...
please answer
I'm not displaying the picture but its in in a grid showing two arrows forming an angle. It doesn't have the angle or x/y components, nothing... so i dont know how to find the magnitude and direction...
