What happens when you separate the mixture of flour and sugar? The sugar in the flour will dissolve in the water. And the flour will continue to float on the surface of the water. Use a spoon (preferably a plastic one) to skim the flour particles from the surface of the container. Collect the flour […]
Do solar calculators die?
Do solar calculators die? Yes. They can become fine paperweights when they finally stop performing as calculators. How long do solar-powered calculators last? 5-15 years How can I charge my solar calculator without the sun? You can charge solar lights without sunlight while placing solar panels directly underneath a household light to charge them speedily. […]
How often does the House of Representatives get elected?
How often does the House of Representatives get elected? Members of the U.S. House of Representatives serve two-year terms. All 435 members get elected every midterm and presidential election year. Why do Senators have 6 year terms? To guarantee senators’ independence from short-term political pressures, the framers designed a six-year Senate term, three times as […]
Can a body have zero acceleration but have velocity?
Does dark energy cause inflation?
Does dark energy cause inflation? Dark matter and dark energy may have driven inflation, the exponential expansion of the Universe moments after the Big Bang. A new cosmological model proposed by physicists, which takes dark inflation into account, is the first to outline a precise chronology of the main events during the early history of […]
What are the three categories of adaptation?
What are the three categories of adaptation? There are three different types of adaptations: Behavioural – responses made by an organism that help it to survive/reproduce. Physiological – a body process that helps an organism to survive/reproduce. Structural – a feature of an organism’s body that helps it to survive/reproduce. What is a person who […]

Can freezing water break rocks?
Can freezing water break rocks? Freeze-thaw The formation of ice can also break rocks. If water gets into a crack in a rock and then freezes, it expands and pushes the crack further apart. When the water freezes, it expands and makes the crack even bigger. What happens to rocks when water freezes in it? […]
How do you calculate accelerating potential?
How do you calculate accelerating potential? The kinetic energy of an electron accelerated through a potential difference of V volts is given by the equation: ½ mv2 = eV where e is the electron charge (1.6×10-19 C) [You must be given the electron charge and Planck’s constant in order to answer this question]. What is […]
