What is the value of 1 pico Farad? 1/1,000,000,000,000 What is capacitance value? Capacitance is expressed as the ratio of the electric charge on each conductor to the potential difference (i.e., voltage) between them. The capacitance value of a capacitor is measured in farads (F), units named for English physicist Michael Faraday (1791–1867). A farad […]
What is the point of neutrons?
What is the point of neutrons? Neutrons bind with protons and one another in the nucleus via the nuclear force, effectively moderating the repulsive forces between the protons and stabilizing the nucleus. How quickly does a neutron bomb kill? two days Is there a doomsday bomb? In a 2-part episode of the TV show The […]
What sound intensity is defined as the level of pain?
Is loudness related to frequency?
Is loudness related to frequency? Now when talking about sound waves the sound level of a noise (loudness), it is proportional to the intensity of the source. The loudness of a sound does not seem to depend on frequency. But according to the equation above, intensity DOES depend on frequency. How loud is 1000hz? Using […]
Which are characteristics of a ray when it hits a boundary and refracts but not?
Which are characteristics of a ray when it hits a boundary and refracts but not? F. Only these two options are characteristics of a ray when it is refracted, but not when it is reflected. In fact: Reflection occurs when a ray hits the interface between two mediums and bounces off back. When it is […]
What does tightening a string do?
What does tightening a string do? Tension refers to how tightly the string is stretched. Tightening the string gives it a higher frequency while loosening it lowers the frequency. When string players tighten or loosen their strings, they are altering the pitches to make them in tune. The density of a string will also affect […]
Is Q A joule or kilojoule?
What are the 3 basic types of scaffolds in the construction industry?
What are the 3 basic types of scaffolds in the construction industry? Workers who use scaffolds can be divided into three groups: Suspended Scaffolds. Supported Scaffolds. Aerial Lifts. What is the narrowest scaffolding? Narrowest 600mm scaffold tower For our narrowest tower try the stair tower. It comes in a 600mm wide frame so it can […]
How do you explain combustion?
How do you explain combustion? Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat. The original substance is called the fuel, and the source of oxygen is called the oxidizer. The fuel can be a solid, liquid, or gas, although for airplane propulsion the fuel is usually […]
What is the function of semiconductor?
What is the function of semiconductor? A semiconductor can help controlled flow of electricity. The basic function of such a device is to switch ON and OFF the flow of electricity as and when required. A semiconductor device can perform the function of a vacuum tube with hundreds of times its volume. What is N […]
