Two objects with masses my and m2 are hung by a string through a pulley. In this system, mi is greater than m2, while the string and the pulley are massless. Initially, both masses are held at rest at the same height.
What will happen when the objects are released?
A)
mi will move upward with an acceleration of
(m1 - m2)
9.
(m1+
m2)
B)
m2 will move upward with an acceleration of
(m1 + m)
9.
(m1-m2)
m1 will move downward with an acceleration of
(m1 - m2
9.
(m1+ m2)
C)
D)
m2 will move downward with an acceleration of
(mi + m2)
9.
(m1-m2)

The answer is  the potential energy of the bob at position b is 1.47 joules.if the maximum height of the bob is 0.45 meters when it swings back,1.323   joules of energy was transformed to thermal energy.hope this

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
