After the discovery of uranus, astronomers calculated its orbit and predicted its position in the sky using kepler's laws of planetary motion, which had been known since the early 17th century. however, they soon discovered a small discrepancy between the predicted and actual positions of uranus. as a scientist, what should you do when presented with such a conflict between prediction and observation?
select all that apply: a. verify that your observations are correctb. consider whether kepler's laws need to be modified to account for the new observationsc. think about what else might cause the observed discrepancy ord. consider that uranus may not be a planet

•• al and bert are jogging side-by-side on a trail in the woods at a speed of 0.75 m/s. suddenly al sees the end of the trail 35 m ahead and decides to speed up to reach it. he accelerates at a constant rate of 0.50 m/s2, while bert continues on at a constant speed. (a) how long does it take al to reach the end of the trail? (b) once he reaches the end of the trail, he immediately turns around and heads back along the trail with a constant speed of 0.85 m/s. how long does it take him to meet up with bert? (c) how far are they from the end of the trail when they meet?
