Determining a Person’s Power through height/work Power is denoted by the formula‚ P = mgh/t. In lifting a bag‚ work is done. So in order to get power we recorded our weight‚ measured the weight of the bag‚ and the time it took to lift a bag. The experiment is done in two ways 1) with constant time and 2) with constant height. In this way‚ we can compare and know if there will be a difference in the amount of power exerted by a person if either time or height will be constant. The formulated

No. Statistical methods are used to establish the deviations in the measurement. 2. Distinguish between random (statistical) error and systematic error‚ and give an example of each. Random errors are caused by unknown and unpredictable changes in the experiment like mechanical

To determine the heating and cooling curve of water Design: What we are going to do is investigate the phase changes and what the heating curve of water is. We are going to do this is by heating up 100ml of water on a Bunsen burner then adding ice cubes. Use a thermometer to measure the temperature every 30 seconds until it reaches a plateau. Hypothesis: As more time passes‚ the temperature of the water increases. Independent variable: Time Dependent variable: Changing water temperature

6. Applications * Is it possible to add heat to a body without changing its temperature? Yes. It is possible to add energy to a body (in the form of heat) and not raise its temperature by causing a phase change. When you heat ice it takes energy to convert it from ice to water‚ but does not change the temperature of the body until it is all converted. The principle behind this is what we call latent heat. It refers to the energy (or heat) required to change the state of a substance without changing

and the world‚ and this connection is believed to continue throughout time. From the moment god created humanity (Gen. 1:26)‚ we were created for the one purpose to protect the earth. But it is in the story of Noah that we perhaps truly learn about the role that God had created us for‚ to protect nature. As soon as humanity becomes aware of the natural destruction‚ like in the Noah’s Ark story‚ only then can we fulfill our divine duty to protect all living things. The Torah makes you believe
