Is it true that hypothesis is an educated guess? A hypothesis is an educated guess or prediction about the relationship between two variables. The objective of a hypothesis is for an idea to be tested, not proven. The results of a hypothesis test can demonstrate only whether that specific hypothesis is or is not supported […]
Which is stronger neap or spring tides?
Which is stronger neap or spring tides? Spring tides have higher high tides and lower low tides whereas neap tides have lower high tides and higher low tides. Hence, the range (difference in water level between high and low tide) is much larger in a spring tide than in a low tide. What months do […]
What is called where muscle build strength against resistance?
What is called where muscle build strength against resistance? Resistance training (also called strength training or weight training) is the use of resistance to muscular contraction to build the strength, anaerobic endurance and size of skeletal muscles. When you do resistance training repeatedly and consistently, your muscles become stronger. What is the difference between muscular […]
Does eating fat make you fatter?
Does eating fat make you fatter? To be clear, neither carbohydrates nor fats on their own cause you to gain weight – it’s just that you tend to eat more calories when your diet is focused on carbohydrates over fat. Being in a caloric surplus causes you to gain weight. Does cutting carbs reduce belly […]

He was the first modern European scientist to propose that Earth and other planets revolve around the sun, or the Heliocentric Theory of the universe. Did the church silence Galileo? Galileo’s discoveries were met with opposition […]
At what temperature does superconductivity occur?
At what temperature does superconductivity occur? Superconductivity, complete disappearance of electrical resistance in various solids when they are cooled below a characteristic temperature. This temperature, called the transition temperature, varies for different materials but generally is below 20 K (−253 °C). How can we destroy superconductivity? The superconducting state can be destroyed by a rise […]
Does a resistor change the current?
Why would a bird need low bone density?
Why would a bird need low bone density? Bird skeletons don’t weigh any less than mammal skeletons of the same size. After all, thin, hollow bones are more fragile, so they’d need to be made of much denser material to keep from breaking all the time. That density also helps with flying, according to research […]

How is an electron removed?
How is an electron removed? Ionization is the process in which one or more electrons are removed from an atom or molecule, thereby creating an ion. In order to remove an electron from an atom, enough energy must be supplied to break the bond between the negatively charged electron and the positively charged nucleus; this […]
