Glycerin, with a density of 1.26 grams per cubic centimeter [g/cm3] and a viscosity of grams per centimeter second [g/(cm s)] is pumped through a -centimeter [cm] radius steel pipe at an average velocity of centimeters per second [cm/s]. Determine the Reynolds number in the pipe for the system and indicate if the flow is laminar, transitional, or turbulent. The Reynolds number in the pipe for the system is:

Specify the type of flow.

a. turbulent
b. transitional
c. laminar

Amajor difference radio waves, visible light, and gamma rays is the of the photons, which results in different photon frequencies and wavelengths

By what primary heat transfer mechanism does the sun warm the earth?

Afaulty model rocket moves in the xy-plane (the positive y direction is vertically upward). the rocket's acceleration has components ax(t) = ? t2 and ay(t) = ? ? ? t, where ? = 2.50 m/s4 , ? = 9.00 m/s2 , and ? = 1.40 m/s3 . at t = 0 the rocket is at the origin and has velocity ~v0 = v0x ? i + v0y ? j with v0x = 1.00 m/s and v0y = 7.00 m/s. (a) calculate the velocity and position vectors as functions of time. (b) what is the maximum height reached by the rocket? (c) sketch the path of the rocket. (d) what is the horizontal displacement of the rocket when it returns to y = 0?
