CBSE Class 10 Science Sample Paper Set C

SECTION - A

1. Why solar cookers are covered with glass plate and painted black from inside and outside. 

2. Define electric potential at a point. A current of 2A passes through circuit for 1 minute. If the potential difference between 2 terminals is  3V. Calculate work done in transferring charge between two terminals.

3. Give reasons:-

   a) If wire is stretched to double its length then its resistance becomes 4 times but resistivity remains same.

   b) Cord of heater does not glow while heating element does.

   c) Voltmeter is always connected parallel across the two terminals.

4. a) If magnetic field lines are crossed at a point. What does it indicate?

   b) Draw magnetic field lines of a circular coil carrying current. On what factors does the strength of field depends.
