What is the negative connection in a battery called? Energy cannot be created or destroyed, but it can be saved in various forms. One way to store it is in the form of chemical energy in a battery. When connected in a circuit, a battery can produce electricity. A battery has two ends — a […]
What are the base units the SI units are based on number?
What are the base units the SI units are based on number? It comprises a coherent system of units of measurement starting with seven base units, which are the second (the unit of time with the symbol s), metre (length, m), kilogram (mass, kg), ampere (electric current, A), kelvin (thermodynamic temperature, K), mole (amount of […]
What are the qualities of a good software?
What are the qualities of a good software? It can be measured on: Budget. Usability. Efficiency. Correctness. Functionality. Dependability. Security. Safety. Are two kinds of software products? There are two types of software : System software. Application software. Why is requirements elicitation a difficult task? Sometimes, Stakeholders or users are unable to specify or clearly […]
Which is the low frequency noise?
Which is the low frequency noise? Low frequency noise, considered as the frequency range from about 10Hz to 200Hz, causes extreme distress to a number of people who are sensitive to its effects. The noise levels are often low, in the region of a subject’s hearing threshold, where there are large differences between individuals. How […]
What are 4 things we automatically process?
What are 4 things we automatically process? Some examples of automatic processes include motor skills, implicit biases, procedural tasks, and priming. The tasks that are listed can be done without the need for conscious attention. Implicit biases are snap judgments that people make without being aware that they made them. What three things do we […]
What is the relationship between atmospheric pressure and altitude?
What is the relationship between atmospheric pressure and altitude? Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than […]
Which waves can carry information?
Which waves can carry information? While many different types of EMF are used to convey information over distance, the most common are radio waves, also called radiofrequencies. This is a wide spectrum ranging from tens of kilohertz to 300 gigahertz. Within this spectrum, frequency bands are allocated to each use. How do we use waves? […]
What is diagram example?
What is diagram example? In science the term is used in both ways. For example, Anderson (1997) stated more generally: “diagrams are pictorial, yet abstract, representations of information, and maps, line graphs, bar charts, engineering blueprints, and architects’ sketches are all examples of diagrams, whereas photographs and video are not”. Why is a diagram important? […]
Where is the potential energy of the system the greatest?
Where is the potential energy of the system the greatest? Where is the potential energy of the system the greatest? At the highest point of the oscillation. At the new equilibrium position of the oscillation. Is potential energy negative or positive? This is a negative value for two reasons; the force acting between them is […]
How quick can evolution happen?
How quick can evolution happen? Across a broad range of species, the research found that for a major change to persist and for changes to accumulate, it took about one million years. How Fast Is human evolution? A study by anthropologists John Hawks, Henry Harpending, Gregory Cochran, and colleagues suggests that human evolution has sped […]
