Suppose a team of astronomers recently discovered a solar system similar to our own, but in an earlier stage of development. Based on how the planets of our solar system formed, which two observations would you expect the astronomers to make? dense, rocky objects orbiting near the central star thick clouds of liquid helium orbiting near the central star planetesimals orbiting in different directions around the central star clusters of rock loosely held together by gravity the rate of rotation slowing down for all objects

What component of earth’s atmosphere exists entirely as a result of photosynthesis?

3. a worker pushes a 30.5 kg polished stone along a polished table with a force on bonin a straight line for 5.20 s after starting from rest. there is no friction between thestone and the table. at the end of the table. the stone is hooked to a cable with a lengthof 62.0 cm to rotate it to a rough table to store until they can be picked up. the roughtable has a coefficient of static friction 0.702 with the polished stone. remember that 8= 9.80 m/s2a) what is the speed of the stone when it is hooked to the cable? b) what is the tension in the cable while the stone is rotating? (there is still nofriction)c) how much force is needed to make the stone begin sliding from rest on therough table? ius = 0.70262.0 cm30.5 kg20.5 kg6= 0
