How do you add two frequencies? You just add them by connecting a wire with one to a wire with the other together at a circuit node. Often it’s helpful to have a resistor on each to balance input impedances but that only affects the total amplitude of each frequency not their “mixing”. What happens […]
What happens when you separate the mixture of flour and sugar?
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 […]
Is a theory an educated guess?
Is a theory an educated guess? In reality, they are quite different. A hypothesis is an educated guess or prediction about the relationship between two variables. But, because theory is a result of scientifically rigorous research, it is more likely that the theory is true (as compared to a single hypothesis). What is a good […]

Will C freeze water?
Will C freeze water? Ordinarily, the freezing point of water and melting point is 0 °C or 32 °F. The temperature may be lower if supercooling occurs or if there are impurities present in the water which could cause freezing point depression to occur. Under certain conditions, water may remain a liquid as cold as […]
What are the 3 models of light?
What are the 3 models of light? Further Reading Color and light. The photon model of light. The ray model of light. The wave model of light. What are two light models? As far as I’m aware, there are two different (and almost contradictory) models that describe the behavior of light: light as a wave […]
What triggers anger in the brain?
What triggers anger in the brain? Anger starts with the amygdala stimulating the hypothalamus, much like in the fear response. In addition, parts of the prefrontal cortex may also play a role in anger. People with damage to this area often have trouble controlling their emotions, especially anger and aggression. What shape does the brain […]
What is the distance between two successive waves?
What is the distance between two successive waves? wavelength How is wave height calculated? The wave height is the vertical difference between a wave crest and a wave trough. The wave velocity (celerity) equals the wave length divided by the wave period. Sea reports give the significant wave height. This is calculated from the height […]
Can plants survive without vascular tissue?
Can plants survive without vascular tissue? Plants that lack vascular tissue, which is formed of specialized cells for the transport of water and nutrients, are referred to as non-vascular plants or bryophytes. Non-vascular embryophytes probably appeared early in land plant evolution and are all seedless. These plants include liverworts, mosses, and hornworts. What lacks vascular […]
Who attacked first in the French and Indian War?
Who attacked first in the French and Indian War? Washington moved within about 40 miles of the French position and set about building a new post at Great Meadows, which he named Fort Necessity. From this base, he ambushed an advance detachment of about 30 French, striking the first blow of the French and Indian […]
