Question: Is the sound:

The Company is a manufacturer of Muhibah cylindrical aluminum cans. The owner intends to reduce the cost of production. The burden productional is proportional to the surface of the foil used. The volume that each function of tin is 1000cm cube (1L).

1.

Answer: for a volume of cylinder = r ^ 2 * pi * h outdoor space = 2 * pi * r ^ 2 +2 * pi * h * r

1. let size = 1000 and solve the equation h = 1000 / (pi * r ^ 2)
2. substitute in the equation of this area outside. for S h = 2 * pi * r ^ 2 2000 / R after simplification
3. find dS / dr = 4 * pi * R-2000 / r ^ 2
4.

Grade 8 science homework question!?

Jan 20, 2009 by Santastinks | Posted in Homework Help

Question: The doubtful is from the Nelson Science & Technology 8 textbook page 98 number 2.

Here is the ask:
Imagine you have travelled to a planet that has twice the force of grimness of Earth. You have taken a solid with a mass or 1kg with you. Describe its mass, bias, and volume on this planet compared with that on Earth

Answer: it would have the same bulk and volume, but twice the amount of weight. this is because both volume and mass are ratios, volume is (length x wideness x height) and mass is (density/volume)

Encyclopedia of Space Science & Technology 2 Volume Set | RAPIDSHARE

Researchers in optics, materials processing, and telecommunications desire a naming that can take under one's wing a irritable reading of a billion of central topics in lacuna science. The two-volume Encyclopedia of Span Science and Technology represents an hopeful omnium gatherum of the underlying real principles of rockets, satellites, and pause stations; what is known by astronomers about the sun, planets, galaxy, and sphere; and the form of the lapse habitat on android and other biological systems. The Encyclopedia covers a species of main topics, including:
