Answer:

A magnet has two poles.

Like poles repel each other and unlike poles attract

An electromagnet is used to separate large masses of iron scrap.

The strength of the magnetic field of an electromagnet is increased by inserting a core of soft iron.

In a torch we use a dry cell as the source of electricity.

To light a table lamp and to run a refrigerator, we use mains as the source of electricity.

A group of two or more cells is called a battery.

Conductors pass electricity through them.

This is ur answer....

<em></em>

<em>The heat is transferred by the process of conduction of heat. </em>

<em> It is given that, Jimmy held the end of a metal bar over a fire while holding on to the opposite end.     </em>

<em> After some time, the end he was holding began to get very hot. </em>

<em> The process of traveling heat from one end of the bar to the other end is called conduction. It is the process of transfer of heat by the interaction of particles and motion of electrons.</em>

An object placed on an equal-arm balance requires 12 kg to balance it. when placed on a spring scale, the scale reads 12 kg. eve
Mkey [24]
<span>equal-arm balance = 12 kg spring scale = 2 kg The equal arm balance measures the mass of an object by using a counter mass on the opposite plate of the balance. The force of gravity affects both the mass being tested and the mass standards being compared against equally. So if the local gravitational field changes, those changes affect both the tested mass and the standard masses equally. Contrast that to the spring scale. In that scale, the spring provides a calibrated level of force irrespective of the local gravitational field. So if the local gravity is higher, the force indicated also is higher. And if the gravitational field is lower, the indicated force is also lower. The strength of the spring DOES NOT CHANGE with changes in the local gravitational field.</span>
