What is the most likely reason that a hypothesis would be useful even? What is the most likely reason that a hypothesis would be useful even if experiments show that it is false? New hypotheses and experiments can be developed that better fit the observations made during the original experiments. Why is it smart to […]
What two types of digestion occur in mouth?
What two types of digestion occur in mouth? Mechanical and Chemical Digestion There are two kinds of digestion: mechanical and chemical. Mechanical digestion involves physically breaking the food into smaller pieces. Mechanical digestion begins in the mouth as the food is chewed. What does the stomach do in the digestive system? Stomach. The stomach is […]
Where an object is located in relation to another object?
Where an object is located in relation to another object? 7.1 An object is in motion if its position changes relative to another object. To decide if you are moving, you can use your chair as a reference point. A reference point is a place or object used for comparison to determine if something is […]
What happens when two magnets are placed side by side?
What happens when two magnets are placed side by side? Opposite poles of a magnet attract each other, whereas like poles repel each other. However, when lined up with another north-seeking pole, the two magnets would push away from each other because their forces are not compatible. Is Venus a permanent magnet? Venus is a […]
What is the relation between refractive index and intensity?
What is the relation between refractive index and intensity? The intensity of light (as calculated from time average of the poynting vector) is given by I=(1/2)ϵvE20. Here the intensity is dependent on the velocity of light in the medium. The refractive index also depends on the velocity of light. What is the speed and intensity […]
What factors affect collision theory?
What factors affect collision theory? Key Takeaways Reactions occur when two reactant molecules effectively collide, each having minimum energy and correct orientation. Reactant concentration, the physical state of the reactants, and surface area, temperature, and the presence of a catalyst are the four main factors that affect reaction rate. What are the 5 major factors […]
Is eccentricity positive or negative?
Is eccentricity positive or negative? In mathematics, the eccentricity of a conic section is a non-negative real number that uniquely characterizes its shape. How is eccentricity calculated? The formula to determine the eccentricity of an ellipse is the distance between foci divided by the length of the major axis. What does a negative eccentricity mean? […]
Where are the inner transition elements?
Where are the inner transition elements? The inner transition metals are found in the f-block, usually put at the bottom of the Periodic Table. These elements were sometimes called rare earth metals due to their extremely low natural occurrence. What are transition metals and their properties? The transition metals have the following physical properties in […]
How do I filter rows instead of columns in Excel?
At what temperature does all motion cease theoretically?
At what temperature does all motion cease theoretically? A temperature scale whose zero point is absolute zero, the temperature of 0 entropy at which all molecular motion stops, -273.15° C. The size of a degree Kelvin is the same as the size of a degree Celsius. Which temperature does all molecular motion steps? Step by […]
