Which of these diagrams best represents the steps in the formation of planets?
a) the sun is born > the clouds rotate at high speed > the clouds flatten into an elliptical disc > the planets are born
b) the clouds flatten into a disc > the sun is born > the clouds condense > the planets are born
c) the clouds of dust and gases rotate at high speed > the clouds condense > the sun is born > the planets are born
d) the clouds of gases condense > the clouds rotate at high speed > the clouds flatten into an elliptical disc > the planets are born

Awater balloon launcher uses an elastic band with a spring constant of 115 n/m to use thee launcher you stretch thee band back with a balloon n it the water balloons have a mass of 1.3 kg a) if you stretch the band by 0.8 m, what elastic force will the band exert? b) with the band stretched 0.8 m, how much elastic potential energy is stored in the spring? c) if you release the band, it pushes forward. what is the kinetic energy of the balloon when it reaches the natural length of the band? d) what is the speed of the balloon when it reaches the natural length of the band?
