Scalar quantity has magnitude only,example arespeed/time/distance/massVector quantity have both magnitude and direction,example areweight/force/displacement(Any one example for each case)Show the direction is the opposite from the originalPeriod is the time taken for one complete oscillation of the ...
The technique involves taking vector and scalar products of successive magnetic measurements; the resulting scalar quantity is insensitive to slow field variations as well as sudden ones (i.e., tangential discontinuities) and provides a measure of total noise. We illustrate this analysis by ...
Scalar tells the magnitude or how fast the car is moving. Velocity is a vector quantity that describes the magnitude and tells the direction of where the car is going. Therefore, a vector, by definition, is a physical quantity with both magnitude and direction. Other scalars and vector pairs...
Scalar multiplication is one of the type of matrix multiplication method where the scalar quantity is multiplied with the vector quantity and the result of scalar multiplication is the vector quantity. Matrix multiplication can be performed under two categories one is scalar multiplication an...
a) Vector : The physical quantity which is specified with magnitude and direction is called a vector. Eg : Displacement, velocity are vectors. b) Scalar : The physical quantity which does not require any direction for its specification is called 'sca
The unit of weight is N but the unit of mass in kg Weight is a vector quantity but Mass is a scalar quantity. Weight is one kind of force but the mass is not a force. Weight can be zero but mass can never. We often confuse that mass and weight are the same or different. Someti...
Must the total energy of a system be conserved whenever its momentum is conserved? Explain why or why not. Explain why momentum is conserved when a ball bounces off the ground. Why is momentum considered to be a vector quantity? Describe and name the different types of ...
Because displacement is a vector quantity, it can be a positive, negative, or zero value. When understanding displacement, it is important to take the starting and ending positions of the object into consideration. By drawing the vector from the starting point to the ending point of an object...
At this stage, we have already imposed the adding up constraint (i.e., out of L goods we have deleted the last). Let p denote the L vector of prices, and x denote income (total expenditure).1 For every individual, define the cost function C(p,u) to give the minimum cost to ...
A scalar distance r between masses m1 and m2, which in three dimensions is equal to: (20) r=(m1x−m2x)2+(m1y−m2y)2+(m1z−m2z)2 A unit vector r^ that provides a direction for accelerations and velocities. A unit vector has a magnitude of 1, which means it can be ...
