Questions & Answers

Q: How many sample papers should I solve for each subject?

It is recommended to solve at least five sample papers for each subject to gain thorough practice and better understanding of the concepts.

Q: How to remember chemical reactions in chemistry?

There are various tricks and mnemonic techniques available to remember chemical reactions. You can also ask your teacher or refer to study materials for effective methods.

Q: Can you explain myopia?

Myopia is a refractive error in which the eyeball elongates, causing distant objects to appear blurry. It can be corrected using concave lenses.

Q: What type of lens is used as a magnifying glass?

A convex lens is commonly used as a magnifying glass to enlarge the size of objects.

Q: How should two identical prisms be arranged to recombine white light?

Two identical prisms should be arranged upside down with respect to each other to recombine white light into a single beam.

Q: Why do iron filings arrange in a certain pattern around a bar magnet?

Iron filings arrange in a pattern along magnetic field lines due to magnetic induction, which causes them to act like tiny magnets and attract each other.

Q: What is the purpose of a fuse in a household circuit?

A fuse is placed between the main connection and the rest of the house to protect the circuit from high electric current. The fuse wire melts when the current exceeds its capacity, breaking the circuit and preventing damage.

Q: What physical quantity is indicated by the pattern of magnetic field lines?

The pattern of magnetic field lines indicates the magnetic field strength and direction at different points around a magnet or current-carrying wire.
