As a physics instructor hurries to the bus stop, her bus passes her, stops ahead, and begins loading passengers. she runs at 6.0 m> s to catch the bus, but the door closes when she’s still 8.0 m behind the door, and the bus leaves the stop at a constant acceleration of 2.0 m> s2. she has missed her bus, but as a physics exercise she keeps running at 6.0 m> s until she draws even with the bus door. (a) calculate ∆t from the instant the bus leaves the stop to the instant the instructor draws even with the door. (b) at the instant she draws even, how fast is she moving? (c) at the instant she draws even, how fast is the bus moving? (d) plot v(t) for the bus and the instructor. (e) plot x(t) for the bus and the instructor. ⦁⦁⦁

Imma say go with a (:

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

Ibelieve the answer above is c but im not sure
