What is the purpose of theory in research?
What is the purpose of theory in research? Theories are formulated to explain, predict, and understand phenomena and, in many cases, to challenge and extend existing knowledge within the limits of critical bounding assumptions. The theoretical framework is the structure that can hold or support a theory of a research study. Why do we need […]
Why can velocity be negative but speed can t?
Why can velocity be negative but speed can t? 2 Answers. Remember that velocity and acceleration are vectors, they have a magnitude and direction. Speed, on the other hand, is a scalar quantity which only has magnitude. So yes, the negative sign indicates a slowing down. What does it mean when position is negative? In […]
What is 4 2He called?
What is 4 2He called? 4/2He or the alpha particle that consists of two protons and two neutrons can be discharged from the nucleus during the disintegration of radioactive decay.

Why do objects transfer heat?
Why do objects transfer heat? All matter contains heat energy. Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases. The transfer or flow due to the difference in temperature between the two objects is called heat. How is heat different from temp? Heat […]
