The similarity between thermal energy, heat and temperature?
Vitek1552 [10]
Heat energy and thermal energy are the same because heat energy is thermal energy. Also thermal energy and temperature are the same because temperature is measuring heat in degrees Celsius or degrees Fahrenheit. Hope this helps!

Energy energy can be transferred from one form to another we use many Indrajeet Converse in our daily life observe carefully to
aleksandr82 [10.1K]

Answer:

Find the list below.

Explanation:

Energy conversion imply the transformation of energy from one form to another. Examples of these conversions in my home include the following:

1. Chemical energy stored in food is converted to mechanical energy used in working(example sweeping)

2. Chemical energy stored in batteries are used to produce sound energy from the radio.

3. Electrical energy flowing through the wires are used to provide heat energy from the heating device.

4. Electric energy stored in the fan is converted to kinetic energy.

5. Chemical energy stored in petrol is converted to mechanical and electrical energies in the generator.

6. Electric energy supplied by the electric gas cooker is used to generate thermal energy after heating water.

7. Electrical energy flowing through the wires supply light energy in the bulbs.

8. Electric energy is converted to light and sound energy in the televisions.

9. Light energy from the sun is converted to chemical energy in the plants at the garden.

10. Electric energy is converted to sound and light energy in the kitchen blender.

Two large parallel metal plates are 1.2 cm apart and have charges of equal magnitude but opposite signs on their facing surfaces
zheka24 [161]

Answer:

E=1100V/m

                                                                     

Explanation:

Given           required           <u>solution</u>

V=6.6v         E=?                   V=Ed ;    V is the potential difference between                                                              

d=D/2=1.2cm/2=0.6cm=0.006m             the   halfway                  

                                                               E is the electric field between the two                                                                              

                                                                       plates.

                                                              d is the distance between the halfway.

So we can use the above formula to calculate the electric field.

    V=Ed   from this E=V/d  substitute the values from the given equation.

E=6.6v/0.006m

E= 1100 v/m
