What are the three parts of an atom and where are they located? With the exception of hydrogen, all atoms have three main parts. The parts of an atom are protons, electrons, and neutrons. A proton is positively charged and is located in the center or nucleus of the atom. Electrons are negatively charged and […]
What happens if a digital device is too big to be placed in a Faraday bag?
What is the principle of fiber optical communication?
What is the principle of fiber optical communication? The optical fibre is a device which works on the principle of total internal reflection by which light signals can be transmitted from one place to another with a negligible loss of energy. Which of the following is the correct advantage of optical communication? Fiber optic cables […]
What is the measure of how much energy is in an object?
What is the measure of how much energy is in an object? Kinetic energy is energy possessed by an object in motion. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of […]
Do murders happen on cruise ships?
Do murders happen on cruise ships? Although cruise ship murders are incredibly rare, they do happen. Murders are usually committed by a person that the victim knows and the majority of cruise ship murders involve arguments that escalate or a previous history of abuse. For obvious reasons murders which happen on cruise ships are very […]
What are the characteristics of mixtures?
What are the characteristics of mixtures? Characteristics of mixtures The substances in a mixture can be separated using physical methods such as filtration, freezing, and distillation. There is little or no energy change when a mixture forms (see Enthalpy of mixing). Mixtures have variable compositions, while compounds have a fixed, definite formula. What are the […]
Can you charge 2 12v batteries in series?
Can you charge 2 12v batteries in series? Charging time will be the same as charging a single battery. Charge more than five batteries by connecting one 12-volt battery charger across each battery in the series, as if each battery were the only one being charged. Charge all the batteries at the same time. This […]
Can you touch dry ice with your bare hands?
Can you touch dry ice with your bare hands? AVOID CONTACT WITH SKIN AND EYES and NEVER HANDLE DRY ICE WITH YOUR BARE HANDS! Dry ice is extremely cold, -107F (-79C) and can cause severe frostbite within seconds of direct contact. (Frostbite is a freezing injury resembling a burn.) Always wear insulated gloves. What is […]
What is the application of FM?
What is the application of FM? Frequency modulation is widely used for FM radio broadcasting. It is also used in telemetry, radar, seismic prospecting, and monitoring newborns for seizures via EEG, two-way radio systems, sound synthesis, magnetic tape-recording systems and some video-transmission systems. What is meant by FM? Frequency Modulation (FM) is the encoding of […]
Why does random error occur?
Why does random error occur? Random error is always present in a measurement. It is caused by inherently unpredictable fluctuations in the readings of a measurement apparatus or in the experimenter’s interpretation of the instrumental reading. They can be estimated by comparing multiple measurements, and reduced by averaging multiple measurements. Which of the following is […]
