IPA Kelas 2

Explanation
The correct answer is A. cahaya (light). Matahari dan lilin (sun and candle) both emit light, making light the source of energy in this context.

Explanation
There are five sources of sound energy.

Explanation
The correct answer is A.ada 2. This suggests that there are two sources of motion energy.

Explanation
The correct answer is B. bunyi. The question asks about the source of energy for the siren on a mobile ambulance. A siren produces sound, which is a form of energy. Therefore, the correct answer is bunyi (sound).

Explanation
The correct answer is A. Minyak tanah atau gas. The question is asking why a stove can turn on, and the correct answer is that it can turn on because there is either minyak tanah (kerosene) or gas as a fuel source.

Explanation
Andi menggunakan setrika untuk menggosok pakaian. Setrika menggunakan energi listrik untuk menghasilkan panas yang digunakan untuk melunakkan dan meratakan serat-serat pakaian. Panas adalah bentuk energi yang dihasilkan dari energi listrik dalam setrika.

Explanation
There are three ways to convert electrical energy into heat energy. These include resistance heating, induction heating, and dielectric heating. In resistance heating, electrical energy is converted into heat energy when current passes through a resistive element. Induction heating involves using electromagnetic induction to generate heat in a conductive material. Dielectric heating occurs when electrical energy is converted into heat energy through the polarization of molecules in a dielectric material. Therefore, the correct answer is B.3.

Explanation
The correct answer is B. rice cooker. A rice cooker is a kitchen appliance specifically designed for cooking rice. It uses a combination of heat and steam to cook the rice evenly and efficiently. A magic jar, blender, and panci (pot) are not specifically designed for cooking rice and may not provide the same level of convenience and precision as a rice cooker.

Explanation
The correct answer is C. kayu bakar. A tungku is a traditional stove or fireplace that is commonly used for cooking or heating purposes. It is typically fueled by burning wood, which produces heat and flames. Therefore, the correct answer is kayu bakar (wood).

Explanation
The correct answer is A. matahari because the sun is a natural source of energy. It emits light and heat, which can be harnessed through solar panels to generate electricity. The sun's energy is renewable and abundant, making it a sustainable source of power. Unlike batteries and car batteries (options B and C), which store energy but need to be recharged or replaced, the sun provides a constant and free source of energy. Water (option D) can also be a source of energy, such as hydroelectric power, but in this context, the sun is a more fitting example of a natural energy source.
