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? […]

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 […]
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 […]
What is the formula for acceleration?
What is the formula for acceleration? Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction. […]
Who discovered positive and negative charges?
Who discovered positive and negative charges? Benjamin Franklin What is charge and write its properties? The charge is a scalar quantity as it has only magnitude and no direction. The charge is just as other fundamental properties of the system like mass. The only difference between mass and charge is that charge is both positive […]
What can I say instead of like?
What can I say instead of like? Thankfully, there are plenty of filler words you can use without the stigma. In place of “like,” try, “for example,” “say,” “nearly,” or “about.” Eventually, you may want to correct for additional words altogether, but for now, use these words as a crutch to stop using “like.” How […]
What are 5 non-renewable resources?
What are 5 non-renewable resources? There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years—hence the name “fossil” fuels. How can we save renewable […]
What else is produced during the replacement reaction of silver nitrate?
What else is produced during the replacement reaction of silver nitrate? Answer. Answer: What else is produced during the double replacement reaction of silver nitrate and potassium sulfate? 2AgNO3 + K2SO4 → Ag2SO4 +. What is produced in a synthesis reaction? Synthesis reactions are reactions that occur when two different atoms or molecules interact to […]
