Is circular motion Translatory? 1) Circular motion is the motion when all the particles of a body move along the circumference of a circle. Translatory motion is a motion when all the particles of a body either move in a straight line or a curved fixed path. What are the three types of translatory motion? […]
Can Exergy be destroyed?
Can Exergy be destroyed? Exergy is the energy that is available to be used. Energy changes from one form to another (see First Law of Thermodynamics). In contrast, exergy is always destroyed when a process is irreversible, for example loss of heat to the environment (see Second Law of Thermodynamics). How is destroyed Exergy calculated? […]
What happens to the mass of two materials when they are mixed?
What happens to the mass of two materials when they are mixed? In all physical and chemical changes, the total number of atoms remains the same, hence when substances interact with one another, combine or break apart, the total weight of the system remains the same. Does the mass change when a solid is formed? […]
Do superconductors transfer heat?
Do superconductors transfer heat? Metallic wire would introduce heat both by conducting it along its length and by generating heat as the electric current passed through it. A superconducting ceramic, on the other hand, is a poor conductor of heat and a perfect conductor of electricity, so it transmits little heat and produces none. Why […]
Does frequency increase current?
Does frequency increase current? In an inductive circuit, when frequency increases, the circuit current decreases and vice versa. What is the frequency range of load rejection? However, the standard (or average) deviation of responses is ± 1870MW/0.1 Hz; giving a range of responses from 4970 to 1230 MW/0.1 Hz. If the lower response of 1230MW/0.1Hz […]
Which best describes disagreement between scientists?
Which best describes disagreement between scientists? The disagreement between scientists is due to to their prospective about different step during the scientific method. Thus, the correct answer is option B. What question Cannot be answered by the scientific method? The scientific method has limitations. It can only answer objective questions based on quantitative facts from […]
Is there a point where the E field is zero?
Is there a point where the E field is zero? Yes. The electric field can be either positive or negative, and between every positive and negative location, there is a “border” where the electric field is zero. Why can electric fields not cross each other? Electric field lines cannot cross. This is because they are, […]
Can a vector of magnitude zero have non-zero?
Can a vector of magnitude zero have non-zero? A vector with zero magnitude cannot have non-zero components . Because magnitude of given vector ˉV=√V2x+V2y must be zero . This is possible only when V2x and V2y are zero. What is the opposite vector? Two vectors are opposite if they have the same magnitude but opposite […]
What volume of oxygen is required for the complete combustion of C2H2?
What volume of oxygen is required for the complete combustion of C2H2? According to reaction, At STP; 1 mole of acetylene that is 22.4L require 5/2 moles of oxygen that is 52×22.4 = 56L for complete combustion. What is the name of C2H2? Ethyne Is C2H2 sp3 hybridized? Answer: Since C2H2 is a linear molecule […]
What are the aims of peer review?
What are the aims of peer review? The primary goals of a peer review are to determine whether a scholarly work falls within the journal’s scope, to check whether the research topic has been clearly formulated, and to decide if a suitable approach has been taken to address the scientific issues involved. What is a […]
