Question
Chapter 3, Problem 1RQ
To determine
The reason for constellations invented in modern times consists of faint stars or located in southern hemisphere.
Expert Solution & Answer
Answer to Problem 1RQ
Old astronomical facilities was not sufficient to observe faint stars with less amount of light is observed.
Explanation of Solution
Most stars in northern hemisphere is so bright. Large amount of light will reach our eyes rom bright starts. So it was possible to easily identify and study them even with instruments with low resolution and power or even with naked eyes.. Ancient Greeks dominated in astronomy before the scientific revolution. With very limited accuracy instruments and facilities, they invented the bright stars in northern hemisphere.
The amount of light reaching eyes from faint stars is very less. So in order to observe them, more technologically advanced instruments with greater accuracy and resolution was required. This happen with modern scientific culture produced as part of European civilization. Galileo and newton has made a major contribution in this development. So, with modern technology, it is possible to observe faint stars in norther hemisphere too.
Therefore, the old astronomical facilities was not sufficient to observe faint stars with less amount of light is observed.

A 1000-kg car traveling east at 30.0 m/s collides with a 950-kg car traveling north at 25.0 m/s. The cars stick together. Assume that any other unbalanced forces are negligible. What is the speed of the wreckage just after the collision?
Please do on paper and show all equations and work done to get to the final answer. Along with any helpful diagrams if needed.
These are a part of my review questions in the book but i keep getting different answers from what the book says, it is not a graded assignment***
Was not explained in my physics 2 lecture, and I'm confused!
