Answer:All three states of matter (solid, liquid and gas) expand when heated. ... Heat causes the molecules to move faster, (heat energy is converted to kinetic energy ) which means that the volume of a gas increases more than the volume of a solid or liquid.
Explanation:well I tried lol she just copied and pasted faster than I could
Answer:
The answer to your question is given below.
Explanation:
From the diagram given in the question, we can see that the bulbs are in parallel connection. This implies that different current will go through the bulb but the same voltage. But the resistance of each bulb is the same, therefore the same current current will go through them.
This can further be understood if we determine the current flowing through each bulb. This is illustrated below:
Voltage (V) = 30V
Resistant 1 (R1) = 15Ω
Current 1 (I1) =..?
V = I1R1
30 = I1 x 15
Divide both side by 15
I1 = 30/15
I1 = 2A.
Voltage (V) = 30V
Resistant 2 (R2) = 15Ω
Current 2 (I2) =..?
V = I2R2
30 = I2 x 15
Divide both side by 15
I2 = 30/15
I2 = 2A.
The overall current(I) in the circuit:
I = I1 + I2
I = 2 + 2 = 4A.
From the illustrations above, we can see that the same current will flow through each bulb as the will current split into two equal parts
Answer:
Part A: The car shoots out of the milk carton at a fast speed.
Part B: Potential Energy
Part C:
1. Gravitational Potential Energy
2. Motion Energy
3. It goes from Motion Energy/Kinetic Energy to Gravitational Potential Energy.
4. Motion Energy
Part D: It is a transfer of energy from the rubber band to the car.
Part E: The car stopped because of gravitation pull that is slowly making the car slow down and eventually stop. The energy is then converted to kinetic energy and heat energy.
Part F: I would think adding force would make the car move again. The type of energy it would have while moving would be: Motion Energy.
Have a great day! :D
<u>The statements that describes energy best as follows:
</u>
- The total amount of energy in the universe remains constant.
- Energy can be converted from one form to another.
- Energy cannot be created or destroyed.
<u>Explanation
:</u>
The Universe is a closed system of energy from where the thermodynamics first law is quoted i.e. the energy in the closed system remains constant.
The energy in the closed system can neither be created nor destroyed in the absence of external energy supply. However, it keeps on changing from one state to another. These are the absolute statements about the total energy existing in the Universe.
There are many energy forms existing in the Universe such heat, mass, vibrations etc. that consistently change their form from one to another but the total energy amount is always constant until external energy is applied to the system.
According to the quantum theory, even an electron absorbs or emits energy while jumping from one energy band to the other. There is never a case where energy can create or destroy in a closed system.
