Answer:
The answers to the questions are
1. Sound <u>e</u>nergy
2. Co<u>n</u>ductor
3. Flow
4. Thermal ener<u>g</u>y (g underlined)
5. Elect<u>r</u>ic current
6. Insulator
7. Light energ<u>y</u>
8. El<u>e</u>ctric circuit
The underlined letters are, e, n, g, r, y, e which can be rearranged to spell energy
Explanation:
1. Sound energy is the wave form of mechanical energy that is transferred by the vibration of the of the medium through which it propagates
2. An electrical conductor is used to conduct electricity from one point to another
3. An object or material flows when it has a smooth motion towards a given direction, such as a river
4. Thermal ener<u>g</u>y is the form of energy that is given off by a body as sensible heat that can be measured as a temperature by a thermometer
5. Electric current is the electricity in a circuit
6. An insulator is a material that limits the flow of electricity or heat
7. Light energy is the form electromagnetic energy which the eye can sense
8. An electric current flows an electric circuit which consist of a source of electricity and an path through which the electric current can easily flow.
