When a person floating in water alone he should be in which position? Body to be in a floating position either vertical or horizontal. Maintaining proximity to other survivors for increased motivation and more importantly prevention of heat loss while ‘Huddling-up’. Are float spas sanitary? Are float tanks sanitary? The interior of a float tank […]
What type of relationship is there between wavelength and frequency?
What type of relationship is there between wavelength and frequency? Frequency and wavelength have both direct and inverse relationships. For instance, if two waves are traveling at the same speed, they are inversely related. The wave with shorter wavelength will have a higher frequency while a longer wavelength will have a lower frequency. This is […]
How high can a 1/2 HP pump push water?
Why do we use lunar calendar?
Why do we use lunar calendar? For 3,000 years, the lunar calendar served the purpose of guiding agricultural affairs and farming activities by dividing the year into 24 solar terms. The solar terms are used to reflect the change of seasons, dividing the year into 4 seasons of exactly three months. Why do the Chinese […]
How fast can a human move?
How fast can a human move? 28Â mphMaximum, Running How fast can a human react? about 250 milliseconds What is the average reaction time for a 13 year old? Both are near the average reaction time for humans which 0.25 seconds. According to our results, children have an average reaction time of 0.25673 seconds and adults […]
What is law of constant proportion class 9th?
What is law of constant proportion class 9th? The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in […]
Why do reaction forces exist?
Why do reaction forces exist? The reaction force is what makes you move because it acts on you. Newton’s Third Law of Motion explains that forces always come in action-reaction pairs. The Third Law states that for every action force, there is an equal and opposite reaction force. This is the reaction force. What is […]
How many principal investigators can you have?
How many principal investigators can you have? Most agencies do not recognize more than one Principal Investigator. Co-Investigator’s are permitted by some funding agencies, but Co-P.I.’s are discouraged. Who can be principal investigator? The Principal Investigator (PI) is an individual who assumes the authority and responsibility for the conduct of a research study. The PI […]
How much power does wind generate?
How much power does wind generate? How much energy do they generate? When the wind is blowing more than 12 miles per hour, each wind turbine can produce 1.5 megawatts of electricity. At reduced wind speeds, electricity production decreases. When wind speed exceeds 45 miles per hour the turbines shut down to protect the machinery […]
How do you find displacement?
How do you find displacement? Displacement can be calculated by measuring the final distance away from a point, and then subtracting the initial distance. Displacement is key when determining velocity (which is also a vector). Velocity = displacement/time whereas speed is distance/time. What does the displacement value mean? Displacement Value can be defined as the […]
