Online notes and solutions CBSE class 6 science - Magnets

In this post, we shared some notes on Magnets from CBSE Class 6 Science.
What are Magnets?
Substances that own the property of attracting iron square measure referred to as magnets. Magnets have 2 ends decision its poles. Two poles, named as, the pole and therefore the South Pole. On establish the poles, the pole is usually painted in red color. the opposite finish of the magnet can, therefore, be the South Pole. In laboratories, magnets square measure painted utterly red in color with a white dot to point the pole.
Types of Magnets
Magnets are of two types: –  natural and artificial magnets. A material which exists naturally and owns magnetic properties is called a natural magnet, example:  magnetite (lodestone). A substance which is made into a magnet by artificial means is known as an artificial magnet. Artificial magnets are formed by magnetizing various shapes of magnetic materials. An iron needle, a rectangular iron bar, a blade or an iron nail can be transformed into a magnet by rubbing a bar magnet over it. Hence, artificial magnets can be of various shapes, example. Bar magnets, horseshoe magnets, dumb-bell shaped magnets, cylindrical magnets, etc. Artificial magnets are more powerful than natural magnets.
Compass 
A compass is an instrument that is employed to search out the directions. it's a skinny magnet supported from a pivot in order that it will rotate freely. The needle is placed over a dial with the directions marked. the complete assembly is placed within an airtight box. The pole of the magnet is painted red. At Compass, the magnet points within the north-south direction. By orientating the dial properly, the directions will be found. within the ancient days, an recent inform device known as the south-pointing fish was wont to grasp the directions, during which the top of the fish pointed towards the south.

PURCHASED GOODWILL METHOD UNDER IND AS 103

The acquisition of subsidiaries results in  Goodwill calculation  and also records net assets of the subsidiary at fair value on the date of acquisition. Let’s get answers to all the questions related to Goodwill, valuation of NCI, and impairment relating to them. Q1 – What are the ways in which an entity can make payment for purchase consideration? ANS: – Cash – Share exchange – Deferred payment – Contingent consideration Q2 – How is deferred payment dealt, when it forms part of purchase consideration? ANS:  The deferred payment is discounted to present value and included in the cost of consideration. At the end of each year, the liability is increased by unwinding the discount, until the payment is settled. For example, An amount of Rs. 108,000 was deferred to be paid after 2 years. The discount rate applicable is 8%. The net present value today of Rs. 108,000 is equal to (108,000 * 1) / (1.08) ^2)= Rs. 92,593 included in purchase consideration. A liability of Rs. 92,59...

NCERT 12th Class Physics Ohm’s Law and Resistance

NCERT 12th Class Physics Ohm’s Law and Resistance Ohm’s Law Ohm’s law:   It states that “the current flowing through a conductor is directly proportional to potential difference between the ends of the conductor provided physical conditions like temperature, pressure etc.  remain the same”. i.e.   VαI or V = IR Here V is apotential difference,I is current and R is Resistance of the conductor. Resistance:  It is the ability of a conductor to oppose the flow of electric current . SI unit of resistance is ohm. Factors on which resistance of a conductor depends: Nature of the material of the conductor Length of the conductor ‘ l’ Area of cross-section ‘A’ Temperature ie R ∝ l R ∝ 1/A R= 𝜌 l/A Where 𝜌 is resistivity of the material of the conductor. What to study the same topic in Hindi? click on  Physics in Hindi The resistivity  of thematerial of a conductor: 𝜌=RA/ l If we have A=1m 2  and  l ...
