What is the pressure at the bottom of a swimming pool that is 3 meters in depth? 29,400 pa What is the pressure at the bottom of a pool? The chart shows that 2.31 feet of water will create one PSI. So in CPO class, I ask the students: “How much pressure is at the […]
What element has 2 protons 2 neutrons?
What element has 2 protons 2 neutrons? Helium What did Chadwick prove? In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, […]
Can COVID-19 affect a newborn baby?
Can COVID-19 affect a newborn baby? COVID-19 is uncommon in newborns born to mothers who had COVID-19 during pregnancy. Some newborns have tested positive for COVID-19 shortly after birth. It is unknown if these newborns got the virus before, during, or after birth. Most newborns who tested positive for COVID-19 had mild or no symptoms […]
What is the difference between stored energy and usable energy?
What is the difference between stored energy and usable energy? The stored energy is termed as potential energy while the working energy is termed as kinetic energy. The electricity used in our homes is also a form of energy because it is a form of usable power. The places from which the different energies are […]
What happens when a cell with 1% salt gets put into a 10% salt solution?
How much force does a falling person have?
How much force does a falling person have? OSHA limits the amount of force that a person should experience during a fall to 1,800 pounds. Forces greater than this can result in internal bleeding, damage, or death. When a personal fall arrest system is used, a shock-absorbing lanyard or fall limiter is the only way […]
What are three types of models?
What are three types of models? Contemporary scientific practice employs at least three major categories of models: concrete models, mathematical models, and computational models. What is simple model? A Simple Model exists to make the skill set required to build financial models more accessible. The intention is to create simple material and facilitate the learning […]
What is the very first step in the proton-proton cycle?
What is the very first step in the proton-proton cycle? The first step in this process is the collision of two protons where proximity permits the strong nuclear force to bind them together. The resulting combination is not stable, and one of the protons will decay to become a neutron, and this forms a stable […]
How do you do a well yield test?
How do you determine instantaneous speed?
How do you determine instantaneous speed? Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. What does instantaneous rest mean? It […]
