Asmall sphere with mass m is attached to a massless rod of length l that is pivoted at the top, forming a simple pendulum. the pendulum is pulled to one side so that the rod is at an angle θ from the vertical, and released from rest. (a) the pendulum just after it realeasewd. draw vectors representing the force acting on the small sphere and acceleration of the sphere. auracy count! at this point, what is the linear acceleration of the sphere? (b) reapeat part (a) for the instant when the pendlum rod is at an angle θ/2 from the vertical. (c) repeart part (a) for the instant when the pendulum rod is vertical. at this point, what is linear speed of the sphere?

I'll do it rn and then answer

The acceleration is 7

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
