Mass is defined as the amount of matter in an object while weight is defined as the force exerted by an object. SI unit of mass is kilograms while SI unit of weight is Newtons. Object weighing 1 kg mass will have 9.8 N weight.
Why electric current is a scalar quantity? What does changing electric field induces? Why is the electric field inside a conductor zero? How does the electric field become zero in a conductor? What is meant by irrotational vector field?
The length of coordinates measured between two different points is termed as distance. The distance possesses the characteristics of scalar quantity by adopting the only magnitude in it. The distance is a relative quantity which shows it always measures with reference to some other point....
What is meant by the permeability of free space? The permeability of free space is a special constant that tells us the magnetic permeability in a vacuum or empty space. This dimensionless quantity is generally represented by \mu_{0} (pronounced as mu zero or mu naught). What do you mean...
In that post, we remarked that whenever one receives a new piece of information , the prior odds between an alternative hypothesis and a null hypothesis is updated to a posterior odds , which can be computed via Bayes’ theorem by the formula where is the likelihood of this information ...
Let , and partition as , where is the level set For each , only finitely many of the are non-empty. By (1), one has Using the ergodic theorem, we conclude that On the other hand, . Thus there exists such that , thus By the Bolzano-Weierstrass theorem, we may pass to a ...
What is a force - A force is a push or pull that acts upon an object. The other words it is the interaction that an object makes with other objects in the surroundings. When unopposed, a force will change the motion of an object. A force can cause an obj
In this release, when you run the RESTORE DATABASE command to restore to a new location – and a transaction log file with the same name already exists in the target location – the database restore activity is canceled, and this error displays: .db or .log file exists. Full restore ...
