Why is it easier to travel to a remote viewing site with an 8" Cassegrain than an 8" Newtonian reflector?
What will be an ideal response?
The Cassegrain design is much more compact, and thus easier to carry, transport, and set up.

An incompressible fluid is flowing through a pipe with a constriction. The pipe is on an incline with an angle of 30.0 degrees. The narrow section is 10.0 m from the wide section and the narrow section is lower than the wide section. The velocity of the fluid in the wide section of the pipe is 4.00 m/s. The diameter of the wide section is 12.00 cm and the diameter of the narrow section is 9.00 cm. The pressure of the fluid in the wide section is 250 kPa. What is the pressure in the narrow section of the pipe? (density of the fluid is 1,000 
A. 295 kPa B. 282 kPa C. 275 kPa D. 252 kPa E. 240 kPa
