Newtons. English (now American) system Feet‚ pounds (mass)‚ seconds‚ pounds (force) cgs system Density The density of a substance is defined as its mass divided by a unit volume ρ=M/V where ρ=density M=mass V=volume In the SI system the base unit for density is kg/m^3‚ whereas in the American engineering system density is commonly expressed as (lb_M)/(ft^3 ) (lb_M=pounds(mass)). Density of water SI system: 1 x 103kg/m3 = 1 g/cm3 American engineering system: 62.4 lbM/ft3.

In the pasted years population has been growing rapidly in MEDC’s and LEDC’s‚ by looking at the crude birth rate and crude death rate we are able to see how the population grows in certain countries. Looking at how high the rates are in a LEDC country and a MEDC country‚ you are able to conclude that you can relate specific factors to different areas of the world. When looking at the population growth of a LEDC there are common factors that appear when looking at the death and birth rates. For

The musculoskeletal system includes bones‚ muscles‚ and connective tissues that all work together to provide the framework for the body‚ create body movements‚ store minerals and lipids‚ produce blood cells‚ and protest the body’s organs. The bones‚ muscles‚ and connective tissue comprise approximately sixty percent of the body’s mass. There are 206 bones and about 700 named muscles of three different types: skeletal‚ cardiac and smooth muscles (Taylor). Musculoskeletal disorders consist of minor

calcium level in the blood and in tissues that need calcium to function properly. When the calcium level increases‚ it will cause symptoms that point to hyperparathyroidism. The extra calcium in the blood comes from the bones so fractures can occur. Blood work as well as bone density scanning will be used to diagnose hyperparathyroidism. Treatment at first will try to correct the high calcium level by dilution with IV fluids and Lasix. If the condition is severe‚ the parathyroid gland that is malfunctioning

exact approximation of quantity as in cars by fuel meters what we get an idea of whether tank is full‚ empty‚ half full etc. The liquid level detector and optimizer play an important role in tanks to indicate the level of liquid of a particular density. In this paper we have proposed a technique to measure the amount of liquid available in tank. This device digitally displays the level of liquid inside the tanks using load sensor. The measurements are taken so the accuracy level is of 96.36%-98%
