Rayap dapat menyebabkan pelapukan pada kayu karena mereka adalah serangga pemakan kayu. Mereka menggali terowongan di dalam kayu untuk mencari makanan dan memakan selulosa yang ada di dalamnya. Proses ini menyebabkan kayu menjadi rapuh dan mudah hancur. Oleh karena itu, rayap dianggap sebagai hewan yang dapat merusak kayu dan menyebabkan pelapukan.

Buah yang diletakkan di tempat terbuka dapat mengakibatkan buah menjadi busuk. Hal ini disebabkan oleh paparan udara, suhu, kelembaban, dan mikroorganisme yang dapat merusak buah. Proses pembusukan ini dapat menghasilkan perubahan warna, tekstur, dan aroma pada buah, sehingga buah menjadi tidak layak konsumsi.

When a person pushes a stalled car, they are applying a force to move the car. This force is known as "dorongan" in Indonesian, which translates to "push" in English.

The correct answer is Blender. A washing machine and a blender both work by rotating an object or a set of objects at a high speed. In a washing machine, the clothes are rotated inside the drum to remove dirt and stains. Similarly, in a blender, the blades rotate at a high speed to blend or puree the ingredients. Both appliances use the principle of rotational motion to achieve their respective functions.

The correct answer is "Energi listrik menjadi panas". This is because an electric iron converts electrical energy into heat energy. When the electric current flows through the heating element of the iron, it encounters resistance, which causes the electrical energy to be converted into heat. This heat is then used to iron clothes and remove wrinkles.

The correct answer states that the stronger the pull, the faster the projectile will be propelled. This is because the force exerted by the pull of the slingshot determines the speed at which the projectile is launched. Therefore, the stronger the pull, the greater the force and the faster the projectile will be propelled.

The correct answer is "Melesat semakin jauh." When the bowstring is pulled back further, it increases the potential energy stored in the bow. When the arrow is released, this potential energy is converted into kinetic energy, causing the arrow to fly further. Therefore, the further the bowstring is pulled back, the farther the arrow will shoot.

The conversion of electrical energy into motion occurs in a washing machine. This is because a washing machine has a motor that uses electrical energy to rotate the drum and agitate the clothes, causing them to move and be cleaned.

The question asks for an exception, meaning that the correct answer should not be a way to identify spoiled food. The smell, color, and shape of food can often indicate if it is spoiled or not. However, the price of food does not necessarily determine if it is spoiled or not. Therefore, the price is the exception in this case.

Gerak adalah perpindahan suatu benda dari posisi awalnya ke posisi lain. Dalam konteks ini, gerak adalah jawaban yang tepat karena menjelaskan tentang perpindahan benda dari posisi awalnya. Energi, gaya, dan pegas tidak menjelaskan tentang perpindahan benda dari posisi awal.

Kayu tidak dapat menghantarkan aliran listrik dengan baik karena kayu adalah isolator listrik. Isolator listrik adalah bahan yang tidak memungkinkan aliran listrik melalui mereka. Sebaliknya, bahan seperti besi, alumunium, dan tembaga adalah konduktor listrik yang baik yang memungkinkan aliran listrik melalui mereka dengan mudah.

Wood is often used for making furniture because of its hardness and ease of shaping. Its hardness ensures durability and longevity of the furniture, while its ability to be easily shaped allows for intricate designs and customization. Additionally, wood is a natural material that adds warmth and beauty to any space. Its availability and affordability make it a popular choice for furniture making.

Rusting occurs when iron or steel comes into contact with oxygen and water. The high salt content in the air near the beach increases the likelihood of rusting because saltwater is more conductive than freshwater, making it easier for the electrochemical process of rusting to occur. Additionally, the salt in the air can accelerate the corrosion process by breaking down the protective oxide layer on the metal surface. Therefore, the high salt content in the air near the beach is the most plausible explanation for rusting to occur easily in that area.

A conductor is a material that allows the flow of electric current through it easily. It has low resistance and can carry electric charges. Therefore, the correct answer is "Konduktor listrik" which translates to "Electric conductor" in English.

Tarikan dan dorongan yang dapat mempengaruhi keadaan suatu benda disebut gaya. Gaya adalah interaksi antara dua objek atau lebih yang dapat menyebabkan perubahan pada kecepatan, arah, atau bentuk benda. Gaya dapat menyebabkan benda bergerak, berhenti, atau berubah bentuk.

The materials that do not conduct electricity well are wood, cloth, and paper.

When iron rusts, it forms a reddish-brown layer of iron oxide on its surface. This layer is commonly known as rust. Therefore, the correct answer is "Coklat kemerah-merahan" which translates to "reddish-brown" in English.

Perkaratan terjadi karena logam besi berikatan dengan air dan udara. Ketika logam besi terkena air, terjadi reaksi oksidasi di mana oksigen dalam udara bereaksi dengan besi, membentuk senyawa besi oksida yang berkarat. Udara yang mengandung oksigen juga mempercepat proses perkaratan ini. Oleh karena itu, kombinasi air dan udara menjadi faktor utama dalam terjadinya perkaratan pada logam besi.

Pertanyaan ini meminta penjelasan tentang hal-hal yang tidak menyebabkan pelapukan. Pada pilihan jawaban, satu-satunya yang tidak menyebabkan pelapukan adalah "Plitur". Pelapukan adalah proses perubahan atau kerusakan yang terjadi pada bahan karena paparan alam seperti cuaca, angin, air, atau suhu. Namun, penggunaan politur pada permukaan bahan dapat melindungi dan mencegah pelapukan terjadi. Oleh karena itu, politur tidak menyebabkan pelapukan.

A timbangan is a tool that uses a spring force to measure the weight of an object. The spring inside the timbangan is compressed when an object is placed on it, and the amount of compression is directly proportional to the weight of the object. Therefore, a timbangan is the correct answer as it utilizes the force of a spring to function.

To make the windows of a house resistant to rainwater, the best option is to paint them. Painting the windows with waterproof paint will create a protective layer that prevents water from seeping through the surface and damaging the wood or other materials. This will ensure that the windows remain durable and unaffected by rain.

Pengecatan dapat mencegah perkaratan pada besi karena cat yang digunakan membentuk lapisan pelindung di atas permukaan besi. Lapisan cat ini akan melindungi besi dari kontak langsung dengan udara dan air, sehingga mengurangi kemungkinan terjadinya oksidasi dan perkaratan. Dengan melakukan pengecatan secara teratur, besi dapat tetap terjaga keindahannya dan lebih tahan terhadap korosi.

Kaca is the correct answer because it does not easily rot or deteriorate like the other options. Kain (cloth), kertas (paper), and kayu (wood) are all organic materials that can be affected by moisture, insects, and other factors that cause decay. Kaca (glass), on the other hand, is an inorganic material that is resistant to these types of deterioration.

The correct answer is Biologi. This is because the question is asking about the type of weathering caused by fungal growth, which is a biological process. Weathering refers to the breakdown of rocks and minerals on the Earth's surface, and there are different types of weathering including physical, chemical, and biological. In this case, the growth of fungi on rocks can contribute to their breakdown and decomposition, which is a biological process. Therefore, the correct answer is Biologi.

The correct answer is "Kayu yang dibakar." When wood is burned, it undergoes a chemical change called combustion. During combustion, the wood reacts with oxygen in the air and transforms into ash, smoke, and gases like carbon dioxide and water vapor. This is a permanent change because the wood cannot be restored to its original form after being burned.
