Speed of Light Determining the speed of light is something that has been a very long and trying process. No one scientist could determine such a thing. Galileo was the first noted scientist to attempt experimentation on the speed of light. Other famous scientist‚ such as‚ Roemer‚ Foucault‚ Fizeau‚ Michelson‚ and Einstein added their own discoveries to the collage of information gathered through the years. Every scientist performed their experiments differently based on the knowledge and ability

Process of Photosynthesis Photosynthesis is process by which plants containing chlorophyll make carbohydrates from water and carbon dioxide in the air in the presence of light. Green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. Photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen‚ on which most organisms depend. Photosynthesis

EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

Light pollution happened slowly at first which was several decades ago it was a process that was hardly noticeable. A light here‚ a light there‚ burning way into the dark nighttime realm‚ helping us see in the darkness when people all their our beds fast asleep. The process still continues today‚ with little thought ever given to what we are stealing away. Our intentions are good but our methods need adjustment‚ and they needs to be done immediately. In fact‚ our methods should have been changed

The effect of temperature on the rate of maggot movement Research and Rationale This experiment is aiming to analyse the behaviour of maggots when they are exposed to light and the effect of that on their movement rate. Behaviour is the way in which animals respond to external factors is known as behaviour. As animals become bigger their behaviour becomes more complex. This is because larger animals tend to have a more complex nervous and hormonal system. Two of the types of behaviour are called

Photosynthesis and cellular respiration go hand in hand‚ but there are differences of the two that most people overlook. Without either of these processes though‚ the human species wouldn’t exist. Along with every other plant or animal. Photosynthesis starts off the cycle‚ with light energy being trapped within the cell and transported into the chloroplast. Water and carbon dioxide follow the similar route of the light energy and as so is collected into the chloroplast. Photosynthesis tends to take

Growth rates and how to calculate them. Growth rates can be tricky to calculate and interpret and many people get confused. So here’s how to get ahead of everyone. Let’s start with a time series where we know the answer. In the example below‚ X starts at 100‚ grows 3%‚ then falls back again‚ then grows 3% again. So over the three years‚ it has grown from 100 to 103. 1 Year 2000 2001 2002 2003 Average CAGR 2 3 4 X Growth X DlnX 100 103 0.03 0.0295588 100 -0.0291262 -0.0295588 103 0.03 0.0295588

If you are interested in learning the benefits of high intensity interval training‚ your concern with personal fitness is likely greater than the average person’s. High intensity interval training at its most effective level is not for the average Jane or Joe. HIIT‚ as it is also referred to‚ can make even a professional athlete weep. But the results are worth it. High intensity interval training has the advantage of requiring much less time to produce great results. It is designed to achieve rapid
