Answer:
The total energy in the system remains the same as the decrease in chemical energy equals the increase in thermal and radiant energy
Explanation:
According to the law of conservation of energy, "energy cannot be created nor destroyed, but only transformed".
This means that for an isolated system, the total energy of the system must remain constant.
In this case, the total energy of the system (the battery and the lightbulb) is the sum of 3 components:
- Chemical energy of the battery
- Thermal energy (the heat produced by the light bulb)
- Radiant energy (the light emitted by the bulb)
The sum of these 3 components of energy must be constant.
At the beginning, all the energy is stored as chemical energy inside the battery. Later, this energy is converted into electrical energy first (when the current starts circulating through the circuit), and finally, this energy is entirely converted into thermal energy and radiant energy as heat and light emitted by the bulb.

Aansi has to increase the temperature for sound wave to be carried more quickly through a metal medium.
<h3>What is temperature?</h3>
The temperature is the degree of hotness or coldness of the object.
When the temperature of any medium is increased, it becomes less dense. The wave travels faster in the rarer medium than the denser medium. So, in less denser medium, wave travel more faster.
Thus, Aansi has to increase the temperature for sound wave to be carried more quickly through a metal medium.

Answer:
Thickness of magazine = 9.42 mm.
Explanation:
Considering vertical motion of spider:-
Initial velocity, u = 0.870 sin 35 = 0.5 m/s
Acceleration , a = -9.81 m/s²
Time, t = 0.077 s
We have equation of motion s= ut + 0.5 at²
Substituting
s= 0.5 x 0.077 - 0.5 x 9.81 x 0.077²
s = 9.42 x 10⁻³ m = 9.42 mm
Thickness of magazine = 9.42 mm.
Answer:
Sun heating a car sitting in a parking lot
Explanation:
The sun heating a car sitting in a parking lot is an example of electromagnetic waves transferring energy.
- Electromagnetic waves are produced from the vibration between electric and magnetic fields.
- These waves can be propagated through vacuum with no particles inside of them.
- The sun produces electromagnetic radiation through the process of nuclear fusion.
- These radiations are used to warm the earth surface.
- The sun heating a car sitting a parking lot is one vivid example.
