calories than others. Donald Hensrud‚ a chair of the Division of Preventive‚ Occupational and Aerospace Medicine stresses that the key to weight loss is burning more calories than you consume. “Because 3‚500 calories equals about 1 pound (0.45 kilogram) of fat‚ you need to burn 3‚500 calories more than you take in to lose 1 pound”‚ he said. I think that in order to achieve your weight loss goals and maintain the results you should develop balanced eating habits and sustainable lifestyle choices

difference. A quantity is a type of measurement while a unit represents a way to measure something. Ex1-A quantity is length; a unit used to measure length is a meter. Ex2- A quantity is mass; kilograms are used to measure mass. 6. List the seven SI base units and the quantities they represent. Meter(length)‚ Kilogram(mass)‚ Seconds(time)‚ Kelvin(temperature)‚ Mole(amt. of substance)‚ Ampere(electric current)‚ Candela(Luminous intensity.) 8.

ABSTRACT This paper describes numerical simulation of a selected soft missile impact small scale test. The main aim of the testing program is to provide data for the calibration and verification of the numerical simulation models for soft missile impact time-history simulation. The experiments are conducted both with dry and fluid filled missiles. The objective of the tests with fluid filled missiles is to investigate the release speed and the droplet size of the fluid spray release in the impact

we would need a lot more ATP and therefore we would need to oxidize glucose at a faster rate and hence our breathing rate would increase so that we can increase intake of oxygen. Variables Independent Variable * Weight: measured in kilograms using a weight scale and will start from 0kg and be increased by 3kg for each trial up until 12kg. Books will be used as weights in this experiment. Dependent Variable * Respiratory rate: measured by counting the number of breaths for 30
