surface of revolution help

It is the time taken by a satellite to complete one revolution around the Earth. Circumference of a circle of radius R + h is 2 p (R+h). Let T be the time period, v the velocity and h the height of the satellite above the Earth's surface. Substituting in the equation, we g..

Find the surface area of revolution formed by revolving the curve given by parametric equations x = 4 t , y = 3 t + 1 from 1 ≤ t ≤ 3 around y -axis. => 40 π square units or 80 square units or 32 7 π square units or 160 π square units or 140 π square units..

Find the surface area of revolution formed by revolving the curve x = 3cos t , y = 3sin t from 0 ≤ t ≤ π 3 about the x -axis. => 9 π square units or 18 π square units or 3 4 ( 3 3 - π ) square units or 9 3 π square units or 4.5 square units..

Find the surface area of revolution formed by rotating the curve x = t , y = t , 5 ≤ t ≤ 9 about the x -axis. => π 6 (37 3 7 - 2 1 2 1 ) square units or π 12 (37 3 7 - 2 1 2 1 ) square units or π 6 (21 2 1 - 3 7 3 7 ) square units or 2416π 3 square units or 2 3..

Electrostatic field lines help us visualize electric fields. Similarly, potential at various points in an electric field can be represented graphically by equipotential surfaces. To help mountain climbers, contour lines are drawn on topographic points through points of..

Surface Energy - We know that work has to be done in order to bring a molecule, from interior to the surface, against the force of cohesion. If the surface area is increased, more molecules can be accommodated at the surface. Increase in surface are..

We know that work has to be done in order to bring a molecule, from interior to the surface, against the force of cohesion. If the surface area is increased, more molecules can be accommodated at the surface. Increase in surface area, results in cooling. To m..

- By polishing the surfaces the friction between the moving surfaces can be reduced...

Surface tension is also related to the intermolecular forces in the liquid. The molecules in liquids are held closely and hence attract each other. A molecule in the bulk of the liquid is attracted equally on all sides so that the net attractive pull on the molecule is zero. However, a m..

Introduction - Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bulk phase ca..
