What is the difference between oscillation and frequency? Therefore oscillation is said to be a periodic motion, that gets repeated at regular time durations. Generally, a wave is measured on the basis of wave parameters which are nothing but amplitude, period, frequency, phase, etc….Comparison Chart. Basis for Comparison Period Frequency Unit Seconds Hertz Is a […]

Which of the following is the example of double displacement reaction? Double displacement reactions take place mostly in aqueous solutions wherein the ions precipitate and exchange of ions takes place. For example, when a solution of barium chloride is mixed with sodium sulphate, a white precipitate of barium sulphate is formed rapidly. These reactions are […]

What cells are responsible for healing? Beyond the stem cell, three other types of cells are critical to the process of tissue repair: fibroblasts, endothelial cells and macrophages. In most wounds, complete replacement of wounded tissue to its original, unharmed state is impossible. Do immunosuppressants slow healing? The principal drugs that can slow wound healing […]

Do you have to have a seatbelt on in the backseat? While the law may not mandate that you wear your seat belt as a backseat passenger, it’s still a good idea to buckle up. In response, many states have enacted laws to encourage backseat passengers in vehicles to buckle up their seat belt just […]

What is scalar projection formula? Remember that a Scalar projection is the vector’s LENGTH projected on another vector. And when we add the DIRECTION onto the LENGTH, it became a vector, which lies on another vector. Then it makes it a Vector projection . It can be understood as this formula: Projectionᵥw = (Componentᵥw) * […]

What is the basic principle of triangulation? In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration. What is strength of figure in triangulation? The […]

Why do we have two high tides per day quizlet? Explain why most coastal regions get two high tides and two low tides each day. Moon gravity pulls on different parts of Earth the Moon gravity causes high tide on the side closest to the Moon low tides occur between the two high tides the […]

What is Dry Cell give an example? A dry-cell battery stores energy in an immobilized electrolyte paste, which minimizes the need for water. Common examples of dry-cell batteries include zinc-carbon batteries and alkaline batteries. What is the rate of ZnCl2 in dry cell? The compositions of dry cell electrolyte are 15% ZnCl2 and 27%NH4Cl in […]

How does System unit work? System Unit. The system unit, like the one above is the case that contains all the electronic components of any computer system. Also on the motherboard is the Central Processing Unit (CPU), processor or brain of the computer. The CPU controls information and tells the other components inside the computer […]

Why do we believe there is dark matter? A sufficiently massive and cold gas cloud can collapse under its own gravity to form stars. By contrast, dark matter cannot lose energy by emitting light. Thus, while conventional matter can collapse into dense objects like stars and planets, dark matter remains more diffuse. Does a parallel […]
