Is isolated ground necessary? An isolated ground, if installed correctly, can reduce some electrical noise. However, complete power conditioning and protection usually requires additional devices such as a surge protector or an uninterruptible power supply. If the receptacle is not installed correctly, it can create a dangerous installation. What is the difference between a grounded […]

What American Indian tribes originated from Mexico? Northern Mexican Indian Middle American Indian. Huichol and Cora. Cáhita. Tepehuan. Tarahumara. Yaqui. Diegueño. Seri. […]
What are 5 ways to conserve energy?
What are derived units give examples?
What are derived units give examples? Answer. Definition: A derived unit is a SI unit ofmeasurement comprised of a combination of the seven base units. Examples: The SI unit of force is the derived unit newton or N. A newton is equal to 1 m. What are derived quantities give examples? Derived quantities are the […]
Can machine change the direction of force?
Can machine change the direction of force? Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied. That’s because a machine doesn’t change the amount of work and work equals force times distance. […]
How entropy is a measure of disorder?
How entropy is a measure of disorder? Because work is obtained from ordered molecular motion, the amount of entropy is also a measure of the molecular disorder, or randomness, of a system. The concept of entropy provides deep insight into the direction of spontaneous change for many everyday phenomena. Does entropy mean disorder? Entropy is […]
How do you interpret a negative Pearson correlation?
How do you interpret a negative Pearson correlation? Negative Correlation A negative (inverse) correlation occurs when the correlation coefficient is less than 0. This is an indication that both variables move in the opposite direction. In short, any reading between 0 and -1 means that the two securities move in opposite directions. What is negative […]
When balancing equations do you balance charges?
When balancing equations do you balance charges? Balance charge. Add e- (electrons) to one side of each half-reaction to balance charge. You may need to multiply the electrons by the two half-reactions to get the charge to balance out. It’s fine to change coefficients as long as you change them on both sides of the […]
What are the six key principles of scientific thinking?
What are the six key principles of scientific thinking? The Six Principles of Scientific Thinking. Extraordinary Claims tells us that extraordinary claims require extraordinary evidence. Falsifiability. Occam’s Razor (Also called the “principle of parsimony”). Replicability. Ruling Out Rival Hypotheses. Correlation vs. What are the principles of scientific knowledge? Among the very basic principles that guide […]
What do you get when you reverse an exothermic reaction?
What do you get when you reverse an exothermic reaction? If the forward reaction is exothermic the reverse reaction will be endothermic, and if the forward reaction is endothermic the reverse reaction will be exothermic. A reaction that produces no change in temperature in an insulated container is said to be athermal. What is forward […]
