A man walks a certain distance at the rate of 5 miles an hour and returns at the rate of 4 miles an hour. If the total time that it takes him is 3 hours and 9 minutes‚ what is the total distance that he walks? 18. An airplane flew in a direct line from its base at the rate of 300 miles an hour and returned over the same route at the rate of 250 miles an hour

Determination of rate of photosynthesis INTRODUCTION Photosynthesis is the major process by which light from the sun is captured by plants‚ algae and some bacteria to produce energy. It is a process in which light energy is converted into chemical energy which is then stored in sugars. Photosynthesis occurs in two stages‚ light-dependant reactions and light-independent reactions. In light-dependent reactions the chlorophyll traps light energy which is then used to excite electrons and split water

The Real Unemployment Rate The real unemployment rate that the government puts out every week does not reflect the true unemployment rate in the United States. There are many people who should be considered unemployed but are not. Some people are not even counted in the labor force when they should be. These people include those who have given up looking for a job for four weeks straight because they are discouraged as well as people who are in the armed forces. I personally thing that both

Crime in Norfolk Tina Tompkins AIU Online Crime in Norfolk I chose to analyze the crime rate in Norfolk‚ Virginia. I’ll be moving there if my fiancé is re-stationed to the Naval base there. I was curious about how safe it is to live there‚ but it’s not at all. The crime rate is greater than I could have imagined and that makes me uncertain about having to live there. I believe more should be done about it‚ and below is what I think would make it better. In the city of Norfolk there is

investigation will show the effect of temperature on the rate of reaction. The Berocca tablet was reacted with hot water (47oC) and then with cold water (20oC). In the hypothesis‚ it was predicted that the temperature will be inverse proportional to the time Berocca tablet reacts with water to produce 50ml of carbon dioxide gas. Through the result table‚ we can see that the hypothesis is supported and it was correct. In the conclusion‚ it was shown that the temperature has the ability to speed up or

The incarceration rates of Norway‚ Australia‚ and Singapore can are much lower compared to the United States. In Norway the murder rate is less than half of that in Australia and robbery rate is significantly lower as well. The rates of all of the three first world countries i researched were surprising to me. I think they are surprising to me because Singapore have a very very low crime rate‚ and i would believe that is because they have very strict rules there compared to other places such as Australia

In this lab the rate of germination in relation to temperature was observed testing the hypothesis‚ if the seeds are exposed to cold temperatures then they will not germinate. In the standard germination test a total of one hundred corn seeds were divided into four groups of twenty-five and each group was used to make a ragdoll. The rag dolls were germinated in room temperature. In the cold test one hundred corn seeds were placed on four layers of moist paper towels in the bottom of a metal tray

Newton’s Law of Cooling The main purpose of this experiment was to find the positive constant “K” for different liquids in the Newton’s Law of Cooling equation‚ in order to determine when it was safe to store food products in commercial restaurant after cooking. The high risk temperature for bacteria growth is between 5 and 60 degrees. However putting hot food into your fridge before this point can cause food poisoning especially in deep containers‚ which is why it is vital that food companies
