How many counts per minute is dangerous? It’s normal to find a range of 7-30 CPM in surroundings. In my opinion, anything below 150 CPM is considered safe, but if the value overshoots this limit, the substance or atmosphere is dangerously radioactive. How many mSv per hour is safe? That’s 1,000 to 2,000 millisievert (mSv). […]
What amount of CO2 is evolved when 50g of CaCO3 is strongly heated?
What amount of CO2 is evolved when 50g of CaCO3 is strongly heated? 22 g of CO2 are obtained from decomposition of 50 g of CaCO3. What type of reaction is CaO CO2 CaCO3? Decomposition What type of reaction is C O2 gives CO2? Combustion reactions involve the reaction of a substance with oxygen gas […]
What are the three major issues in developmental psychology?
What are the three major issues in developmental psychology? Understand the three major issues in development: continuity and discontinuity, one common course of development or many unique courses of development, and nature versus nurture. Where do developmental psychologists work? Developmental psychologists work in a variety of settings, including academia, government agencies, health care facilities and […]
What is the formula of extension?
What is the formula of extension? e is extension = (l-lo); l is the stretched length and lo is original length, and. k is the gradient of the graph above. It is known as the spring constant. How do I calculate my extension length? Analysis For each result, calculate the extension: extension = length – […]
How do you identify radiation type?
How do you identify radiation type? To determine the type of radiation (alpha, beta or gamma), first determine the background count rate, then the source count rate with no absorber. Next, place a sheet of paper between the source and the monitor. If the counts are significantly reduced, the source emits alpha particles. What are […]
What is my weight in the moon?
Where does most of the US electricity come from?
Where does most of the US electricity come from? According to the U.S. Energy Information Administration, most of the nation’s electricity was generated by natural gas, coal, and nuclear energy in 2019. Electricity is also produced from renewable sources such as hydropower, biomass, wind, geothermal, and solar power. Which state produces the most energy? The […]
Can blind people see their dreams?
Can blind people see their dreams? People who were born blind have no understanding of how to see in their waking lives, so they can’t see in their dreams. But most blind people lose their sight later in life and can dream visually. Danish research in 2014 found that as time passes, a blind person […]
What is the energy of orbiting satellite?
What is the energy of orbiting satellite? The kinetic energy of a satellite in a circular orbit is half its gravitational energy and is positive instead of negative. When U and K are combined, their total is half the gravitational potential energy. Why does the speed of a satellite not change? The gravitational force doesn’t […]
Does activity affect pH?
Does activity affect pH? The most favorable pH value – the point where the enzyme is most active – is known as the optimum pH. This is graphically illustrated in Figure 14. Extremely high or low pH values generally result in complete loss of activity for most enzymes. How does pH affect catalytic activity? pH: […]
