Gaya yang ditimbulkan oleh gaya tarik magnet bumi adalah ..
- A.
Gaya magnet
- B.
Gayar gesek
- C.
Gaya gerak
- D.
Gaya gravitasi
Correct Answer
D. Gaya gravitasiExplanation
The correct answer is "Gaya gravitasi". The question asks about the force generated by the Earth's magnetic pull, and the force that fits this description is gravitational force. Gravitational force is the force of attraction between two objects with mass, in this case, the Earth and the object experiencing the force. This force is what keeps objects on the Earth's surface and affects their motion.Rate this question:

Anak panah yang dilepaskan dari busurnya termasuk contoh gaya ...
- A.
Gaya magnet
- B.
Gaya gravitasi
- C.
Gaya gesek
- D.
Gaya pegas
Correct Answer
D. Gaya pegasExplanation
Anak panah yang dilepaskan dari busurnya termasuk contoh gaya pegas karena ketika busur ditarik, energi potensial pegas disimpan dalam pegas busur. Ketika anak panah dilepaskan, energi potensial pegas tersebut berubah menjadi energi kinetik yang mendorong anak panah maju. Ini menunjukkan adanya gaya pegas yang bekerja pada anak panah untuk memberikan dorongan.Rate this question:

Buah jatuh selalu ke bawah, hal itu menunjukkan adanya gaya ....
- A.
Panas
- B.
Dorong
- C.
Gravitasi
- D.
Magnet
Correct Answer
C. GravitasiExplanation
The correct answer is Gravitasi. This is because the question states that fruits always fall downwards, which indicates the presence of a force pulling them towards the ground. This force is known as gravity, which is responsible for the attraction between objects with mass.Rate this question:

Alat untuk mengukur besar kecilnya gaya adalah ....
- A.
Speedometer
- B.
Dinamometer
- C.
Meteran
- D.
Penggaris
Correct Answer
B. DinamometerExplanation
A dinamometer is a tool used to measure the magnitude of force. It is commonly used in physics experiments and engineering applications to determine the force exerted by an object. A speedometer is used to measure the speed of an object, a meteran is used for measuring length, and a penggaris is a ruler used for measuring distance. Therefore, the correct answer for measuring the magnitude of force is a dinamometer.Rate this question:

Dua kutub magnet yang sama jika didekatkan akan ....
- A.
Saling menolak
- B.
Saling mendekat
- C.
Saling terkait
- D.
Saling menempel
Correct Answer
A. Saling menolakExplanation
When two magnets with the same poles are brought close to each other, they will repel each other. This is because like poles of magnets repel each other due to the magnetic field lines generated by each magnet. The magnetic field lines of the two magnets interact and create a force that pushes the magnets away from each other, resulting in them repelling each other.Rate this question:

- D.
Jarum
Correct Answer
D. JarumExplanation
The correct answer is "Jarum" because a compass uses a magnetic needle (jarum magnet) to align itself with the Earth's magnetic field. This needle is typically in the shape of a thin bar or rod, with one end pointing towards the North Pole and the other end towards the South Pole. The needle is magnetized and free to rotate, allowing it to accurately indicate the direction of magnetic north.Rate this question:

Benda yang mudah berubah bentuk ketika diberikan gaya adalah ....
- A.
Batu
- B.
Kayu
- C.
Kaca
- D.
Bata
Correct Answer
C. KacaExplanation
Kaca is the correct answer because it is a material that is known for its ability to easily change shape when force is applied to it. Unlike batu (stone), kayu (wood), and bata (brick), kaca can be easily molded or shaped under pressure or heat. This property of kaca makes it a versatile material used in various industries such as construction, manufacturing, and household items.Rate this question:

Alat yang dapat mencegah terjadinya perpindahan panas adalah ….
- A.
Kipas angin
- B.
Televisi
- C.
Pisau
- D.
Termos
Correct Answer
D. TermosExplanation
A thermos is a device that can prevent the transfer of heat between its contents and the surrounding environment. It is designed with a double-walled container and a vacuum layer in between to minimize heat transfer by conduction and convection. Additionally, the inner walls are coated with reflective materials to reduce heat transfer by radiation. This insulation property of a thermos allows it to keep hot liquids hot and cold liquids cold for extended periods of time, making it an effective tool for preventing heat transfer.Rate this question:

Panas Matahari sampai ke bumi dengan cara ....
- A.
Konduksi
- B.
Konduktor
- C.
Konveksi
- D.
Radiasi
Correct Answer
D. RadiasiExplanation
The correct answer is "Radiasi." Radiasi refers to the process by which the Sun's heat and energy reach the Earth through electromagnetic waves. Unlike conduction or convection, which require a medium to transfer heat, radiation can occur in a vacuum. This is how the Sun's energy is able to travel through the vacuum of space and reach the Earth.Rate this question:

- B.
Konduksi
- C.
Konveksi
- D.
Evaporasi
Correct Answer
B. KonduksiExplanation
Konduksi adalah perpindahan panas melalui zat perantara. Dalam konduksi, panas berpindah dari daerah yang lebih panas ke daerah yang lebih dingin melalui kontak langsung antara partikel-partikel zat perantara.Rate this question:

- A.
Panas matahari sampai ke bumi
- B.
Hawa panas ketika dekat dengan api unggun
- C.
Udara hangat di dekat perapian
- D.
Air panas di teko
Correct Answer
D. Air panas di tekoExplanation
Pernyataan "Air panas di teko" adalah contoh perpindahan panas secara konduksi, bukan radiasi. Radiasi panas terjadi ketika panas dipindahkan melalui gelombang elektromagnetik, sedangkan konduksi terjadi ketika panas dipindahkan melalui kontak langsung antara benda-benda yang memiliki temperatur berbeda.Rate this question:

Bunyi pantul yang terdengar setelah bunyi asli disebut ....
- A.
Gema
- B.
Gaung
- C.
Nada
- D.
Pantulan
Correct Answer
A. GemaExplanation
The correct answer is "Gema". Gema refers to the echo or reverberation of a sound that is heard after the original sound. It is the reflection of sound waves off of surfaces such as walls or mountains, creating a repeated and softer sound. Gaung, Nada, and Pantulan do not accurately describe the phenomenon of sound bouncing back after the original sound.Rate this question:

Bunyi paling cepat merambat pada benda ....
- A.
Padat
- B.
Cair
- C.
Gas
- D.
Lunak
Correct Answer
A. PadatExplanation
The correct answer is "Padat" because sound waves travel fastest through solids compared to liquids, gases, and soft materials. This is because the particles in solids are closely packed together, allowing sound waves to propagate more efficiently. Liquids and gases have more space between particles, causing sound waves to move slower. Soft materials, such as foams or sponges, have a porous structure that absorbs and dampens sound waves, resulting in slower propagation. Therefore, sound waves propagate fastest in solid materials.Rate this question:

- A.
Radiator
- B.
Kontraktor
- C.
Konduktor

Contoh benda yang dapat menghantarkan panas dengan baik adalah ....
- A.
Karet
- B.
Besi
- C.
Kain
- D.
Kertas
Correct Answer
B. BesiExplanation
Besi dapat menghantarkan panas dengan baik karena besi memiliki konduktivitas termal yang tinggi. Ini berarti besi mampu mentransfer panas dengan cepat melalui partikel-partikelnya. Sebaliknya, karet, kain, dan kertas memiliki konduktivitas termal yang lebih rendah, sehingga tidak dapat menghantarkan panas dengan efisien seperti besi.Rate this question:

Benda yang tidak dapat menghantarkan panas dengan baik disebut ..
- A.
Radiator
- B.
Kontraktor
- C.
Konduktor
- D.
Isolator
Correct Answer
D. IsolatorExplanation
An isolator is a material or substance that does not conduct heat well. It acts as a barrier or insulator, preventing the transfer of heat. Unlike conductors, which allow heat to flow through them easily, isolators have high resistance to heat transfer. This makes them useful for insulating purposes, such as in the construction of buildings or in electrical insulation.Rate this question:
