Electric power is a scalar or vector
WebJul 27, 2024 · 1. Current density is a vector, J →, and it must be a vector based on where it shows up in Maxwell’s equations. Current is I = ∫ A J → ⋅ d A →, where A is an area and d A → is a directed normal vector to a differential element of A. So, since it is the dot product of two vectors, current is a scalar. Most of the confusion is not ... WebWe would like to show you a description here but the site won’t allow us.

WebVector acceleration is a scalar acceleration and a direction, eg \ (5 m\,s^ {-2}\) to the right. Treat acceleration as a vector when there is another vector quantity, such as velocity or force ... WebApr 3, 2024 · Hint: Scalar quantities have only a magnitude and do not depend upon any direction, when it comes in comparing to vector quantities of the same type, we have to compare both the magnitude and the direction. Complete step-by-step answer: Power is defined as the energy (or work) per unit time. Power = \[\dfrac{{work(energy)}}{{time}}\] …
WebAdaptive predictive expert control procedure or system, called ADEX, that implements a control strategy in which an adaptive predictive expert controller, called ADEX controller, uses in its adaptive predictive domains a predictive adaptive model that dynamically relates the output of the process to be controlled with an integral function of the control signal … WebExplanation: Mass is a scalar quantity that describes the amount of matter in an object, while weight is a vector quantity that describes the force exerted on an object due to gravity. The weight of an object can be calculated by multiplying its mass by the acceleration due to gravity (g), which is about 9 m/s^2 on Earth.
WebApr 14, 2024 · False. Electric charge is not a scalar quantity, it is a vector quantity as it has both magnitude and direction. In addition to the magnitude of the charge, the direction of the electric field produced by the charge is also an important factor to... WebScalars have a size, while vectors have both size and direction. When adding vector quantities, it is possible to find the size and direction of the resultant vector by drawing a …
WebBoth the vector field and the scalar field can have the same domain, e.g., (R^2) as in your example. But, a scalar field has (R) as codomain whereas a vector field has (R^n) with …
WebSep 11, 2024 · The dot product is known as a scalar product and is invariant (independent of coordinate system). An example of a dot product in physics is mechanical work which is the dot product of force and distance: (14.5.7) W = F → ⋅ d →. The cross product is the product of two vectors and produce a vector. how to escape git bashWebScalars and vectors are two kinds of quantities that are used in physics and math.
