Scalar quantities - Study guides, Class notes & Summaries

UNIT I DIGITAL IMAGE FUNDAMENTALS 1.1. Define Image. An Image may be defined as a two dimensional function f(x,y) where x & y are spatial (plane) coordinates, and the amplitude of f at any pair of coordinates (x,y) is called intensity or gray level of the image at that point. When x,y and the amplitude values of f are all finite, discrete quantities we call the image as Digital Image. 1.2. Define Image Sampling. Digitization of spatial coordinates (x,y) is called Image Samplin...

Scalars Quantities that are fully described by a magnitude alone. Vectors Quantities that are fully described by both a magnitude and a direction. Distance Scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement Vector quantity that refers to "how far out of place an object is" it is the object's overall change in position. Speed Scalar quantity that refers to "how fast an object is moving." Velocity V...

The steps of the scientific method correct answers 1. Observe - ask questions / gather info 2. Hypothesis - identify variables / explain observation / formula 3. Experiment - test predications / check reproducibility 4. Conclude - collect data / accept or deny as theory Occam's razor correct answers If 2 different hypotheses explain the same phenomenon, the one with fewer assumptions is the accepted hypothesis Pseudoscience correct answers theory of creationism (not tested, not a re...

ASVAB Mechanical Comprehension Force ️Ans - Any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape. (a push or pull) Velocity ️Ans - Speed in a given direction Acceleration ️Ans - A change in velocity; the rate of change of velocity with time. Force = Mass x Acceleration ️Ans - Mathematical formula to determine Force For every action (force) in nature, there is an equal (in size) and oppo...
