The sun appears small because it is located far away from the Earth.

In ancient times, people used to create fire by rubbing two stones together. This friction between the stones generated enough heat to ignite dry materials and create fire. This method of creating fire was commonly used by early civilizations before the invention of matches or lighters.

Gaya gesek terjadi antara dua permukaan yang saling bersentuhan dan bergerak relatif satu sama lain. Dalam contoh ini, ban mobil dan jalan raya saling bersentuhan saat mobil bergerak. Ketika ban mobil menggelinding di atas jalan, terjadi gaya gesek antara permukaan ban dan permukaan jalan. Gaya gesek ini menghambat gerakan ban mobil dan menyebabkan keausan pada ban serta mempengaruhi kecepatan mobil.

A dinamometer is a tool used to measure the magnitude of force. It is specifically designed to measure forces such as tension, compression, and shear. It is commonly used in physics and engineering experiments to measure the force exerted by an object. A speedometer, meteran, and penggaris are not suitable for measuring the magnitude of force, making dinamometer the correct answer.

The question asks which part of the animal's body is most utilized by humans for consumption. Out of the given options, "Daging" (meat) is the correct answer as it is the most commonly consumed part of an animal for food purposes.

Semua bentuk tarikan dan dorongan disebut "gaya". Gaya adalah kekuatan yang bekerja pada objek untuk menyebabkan perubahan dalam kecepatan, arah, atau bentuknya. Gaya dapat berupa tarikan atau dorongan, dan dapat berasal dari berbagai sumber seperti gravitasi, magnetisme, atau interaksi antara objek. Dalam fisika, gaya diukur dalam satuan Newton (N).

A ketapel, also known as a slingshot, is an example of a spring force or a pegas force. When the rubber band of the ketapel is stretched, it stores potential energy. When released, the rubber band exerts a force that propels the projectile forward, similar to how a spring force works. Therefore, the correct answer is ketapel.

Pegunungan yang memiliki sedikit pepohonan cenderung memiliki tanah yang tidak stabil dan rentan terhadap longsor. Kehilangan pepohonan dapat mengurangi kekuatan penahan tanah dan meningkatkan risiko longsor. Oleh karena itu, tanah longsor adalah jawaban yang paling sesuai dengan deskripsi tersebut.

This answer is correct because when the plate is thrown and falls to the ground, the force of gravity acting on it causes it to change shape and break. This demonstrates that force can indeed alter the shape of an object.

Indonesia memiliki sumber daya alam yang melimpah karena tanahnya sangat subur. Kondisi tanah yang subur memungkinkan pertumbuhan tanaman yang baik, sehingga Indonesia dapat menghasilkan berbagai jenis komoditas pertanian seperti padi, kelapa sawit, karet, dan cengkeh. Selain itu, tanah yang subur juga mendukung keberadaan hutan yang luas di Indonesia, yang menjadi sumber kayu dan berbagai jenis flora dan fauna. Dengan demikian, kekayaan alam Indonesia dapat dimanfaatkan secara optimal untuk kepentingan pembangunan dan kesejahteraan masyarakat.

The factors that affect the motion of a falling object due to gravity are its weight, shape, and surface area. The price or value of the object has no influence on its motion.

The correct answer is "Radiasi". This is because the sun's heat reaches the earth through radiation. Radiation is the process by which energy is transmitted in the form of electromagnetic waves or particles. In the case of the sun, it emits electromagnetic waves, including heat and light, which travel through space and reach the earth.

Padi bukanlah tumbuhan yang dimanfaatkan untuk pengobatan. Padi adalah tanaman sereal yang biasanya digunakan sebagai bahan makanan utama dalam bentuk nasi. Sementara kumis kucing, lidah buaya, dan jambu biji memiliki sifat-sifat penyembuhan dan sering digunakan dalam pengobatan tradisional.

When we hold the handle of a teapot filled with hot water and our hand feels hot, it proves that heat energy can transfer or move from one object to another.

An isolator is a material or substance that does not conduct heat well. It acts as a barrier or insulator, preventing the flow of heat from one object to another. Unlike conductors, which are materials that allow heat to pass through easily, isolators have high resistance to heat transfer. Therefore, an isolator is the correct term to describe a material or object that does not conduct heat effectively.

Penangkapan ikan menggunakan peledak adalah kegiatan yang merusak ekosistem laut. Peledak akan merusak terumbu karang dan habitat ikan lainnya, serta dapat menyebabkan kerusakan pada ekosistem laut secara keseluruhan.

Mutiara is the correct answer because it is a natural resource that can be renewed. Unlike gold, silver, and amethyst, which are mined from the earth and are finite in quantity, pearls are produced by living organisms (oysters) and can be cultivated through pearl farming. This process allows for the sustainable production and renewal of pearls, making them a renewable natural resource.

Bintang adalah benda langit yang memancarkan cahayanya sendiri. Bintang terdiri dari gas panas yang mengalami reaksi nuklir di intinya, menghasilkan cahaya dan energi. Cahaya yang dipancarkan oleh bintang ini dapat dilihat dari Bumi. Berbeda dengan Bulan yang sebenarnya tidak memancarkan cahayanya sendiri, tetapi hanya memantulkan cahaya matahari yang mengenainya.

Indonesia is considered an agrarian country because a majority of its population is engaged in agricultural activities. This means that a significant portion of the population is involved in farming, cultivating crops, and raising livestock. The agricultural sector plays a crucial role in the country's economy and provides employment opportunities for a large number of people. Therefore, the fact that a majority of the population is involved in agriculture supports the statement that Indonesia is an agrarian country.

The question asks for the term used to describe the ability to do work. "Energi" is the correct answer as it refers to the capacity of a system to perform work. It is a fundamental concept in physics that encompasses various forms such as kinetic energy, potential energy, and thermal energy.

The correct answer is "Pasang naik". This term refers to the rising of sea level, causing an increase in the amount of water and a shift in the coastline. It is commonly known as high tide.

The correct answer is Konveksi. Konveksi refers to the transfer of heat through the movement of fluids, such as air or water. In the context of the given question, the occurrence of land and sea breezes involves the movement of air, which is a form of convection. During the day, the land heats up faster than the sea, causing the air above the land to rise and creating a low-pressure area. This draws in cooler air from the sea, resulting in a sea breeze. At night, the land cools down faster than the sea, causing the air above the sea to rise and creating a low-pressure area. This draws in cooler air from the land, resulting in a land breeze. Therefore, the occurrence of land and sea breezes is an example of heat transfer through convection.

Erosi adalah pengikisan lapisan tanah yang disebabkan oleh gerakan air. Hal ini terjadi ketika air mengalir melalui tanah dan membawa partikel-partikel tanah bersamanya. Erosi dapat menyebabkan hilangnya lapisan tanah yang subur dan mengakibatkan kerusakan lingkungan.

Akar tumbuhan dapat menahan tanah dari air, which means that plant roots can help prevent soil erosion by holding the soil in place. When the soil is covered by plants, their roots create a network that binds the soil particles together, making it less susceptible to erosion caused by water flow. Additionally, the roots also help in absorbing and retaining water, reducing the force of water runoff and preventing the soil from being washed away. Therefore, planting vegetation can be an effective measure to minimize soil erosion.

The correct answer is "Keju" because it is the only option that is not derived from plants. "Wol" is derived from the hair of animals, "Sutera" is derived from silkworms, and "Kayu" is derived from trees. Keju, on the other hand, is a dairy product derived from animal milk.
