Latihan Soal IPA Fisika Kelas VII

Explanation
When a substance is dissolved, it forms ions. In this case, the correct answer is "Hidrogen +", which means that when the zat asam (acidic substance) is dissolved, it will produce hydrogen ions.

Explanation
The correct answer is GLBB Dipercepat. This is because when a coconut falls from its stalk, it is experiencing a change in its velocity, which is an acceleration. The acceleration is caused by the force of gravity acting on the coconut, causing it to accelerate towards the ground. This is an example of a body experiencing a change in velocity due to an external force, which is the definition of GLBB (Gerak Lurus Berubah Beraturan) Dipercepat.

Explanation
Andi bersepeda dengan kecepatan 10 m/s selama 1 menit. Untuk mencari jarak yang ditempuh, kita dapat menggunakan rumus jarak = kecepatan x waktu. Dalam kasus ini, kecepatan Andi adalah 10 m/s dan waktu yang ditempuh adalah 1 menit atau 60 detik. Menggantikan nilai ke dalam rumus, kita dapat menghitung bahwa jarak yang ditempuh oleh Andi adalah 10 m/s x 60 detik = 600 m.

Explanation
When a base and an acid react, they will produce salt and water. In this case, the given options are base, acid, air, and oxygen. Oxygen is not a product of the reaction between a base and an acid. Therefore, the correct answer is water.

Explanation
Berat bukan merupakan besaran pokok karena berat adalah hasil dari gaya gravitasi yang bekerja pada suatu massa. Besaran pokok adalah besaran dasar yang tidak dapat didefinisikan atau diukur dengan besaran lainnya. Suhu, intensitas cahaya, dan kuat arus adalah contoh besaran pokok karena mereka dapat diukur secara langsung tanpa menggunakan besaran lainnya.

Explanation
Berat is not considered a fundamental quantity because it can be derived from the fundamental quantities of mass and acceleration due to gravity. The fundamental quantities are independent and cannot be derived from any other quantities. Suhu (temperature), Intensitas Cahaya (light intensity), and Kuat Arus (electric current) are all considered fundamental quantities as they cannot be derived from any other quantities.
