How the rain is measured? The most common rainfall measurement is the total rainfall depth during a given period, expressed in millimeters (mm). For instance, we might want to know how many millimeters of rain fell over the course of 1 h, 1 day, 1 month, or 1 year. You can easily get a rough […]
What are the 2 branches of the autonomic nervous system?
What are the 2 branches of the autonomic nervous system? The autonomic nervous system has two main divisions: Sympathetic. Parasympathetic. Can you control autonomic nervous system? While involuntary physiological processes are usually outside the realm of conscious control, evidence suggests that these processes, through regulation of the autonomic nervous system, can be voluntarily controlled. Is […]
How much activity is considered active?
What makes good insulation?
What makes good insulation? Polystyrene and plastic foam are both used as insulators as they have small air bubbles trapped inside them. This makes them very good insulators because heat energy can’t flow through them. This stops the movement of air in the space between the two layers of glass and reduces heat loss from […]
What is an example of experimental control?
What is an example of experimental control? Experimental controls are used in scientific experiments to prevent factors other than those being studied from affecting the outcome. For example, suppose a researcher feeds an experimental artificial sweetener to thirty laboratory rats and observes that eight of them subsequently die of dehydration. How do you show experimental […]
What does the orange and white buoy mean?
What does the orange and white buoy mean? These special-purpose buoys have orange symbols on white pillars, cans, or spars. They are used to: Give directions and information. Warn of hazards and obstructions. What side do you pass a red buoy on? right What color is a marker that indicates safe water? Safe Water Markers: […]
What type of relationship exists between the length of wire in the resistance if all other factors remain the same?
What type of relationship exists between the length of wire in the resistance if all other factors remain the same? What type of relationship exists between the length of a wire and the resistance, if all other factors remain the same? Resistance is directly related to length. What type of relationship exists between the length […]
Is the moon dying?
Is the moon dying? The moon isn’t “dead” after all. Newly discovered ridges on the moon’s surface are leading scientists to think that the moon might have an active tectonic system. These ridges, speckled with boulders, could be evidence that, not too long ago, tectonic activity broke apart the moon’s surface. Is Moon cracked? In […]
How many types of flux does a transformer have?
How many types of flux does a transformer have? There are basically two main types of transformers step-up transformer which converts a low input voltage into high output voltage and step-down transformer which converts high input voltage to low voltage. Transformers are used for regulating AC current, rectification, battery charging, etc. How can flux leakage […]
Is liquid a good conductor of electricity?
Is liquid a good conductor of electricity? Substances which allow easy flow of electric current through them are known as electrical conductors. Metals, graphite and certain liquids are a few examples of good conductors of electricity. What liquids are non conductive? Pretty much any oil or organic liquid is non-conducting. These include: Mineral oil. What […]
