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. Ketika busur ditarik, energi potensial elastis disimpan dalam pegas busur. Ketika anak panah dilepaskan, energi potensial elastis tersebut berubah menjadi energi kinetik, menyebabkan anak panah meluncur ke depan. Gaya pegas terjadi karena adanya deformasi pada pegas yang kemudian menghasilkan gaya restoratif yang kembali ke bentuk semula setelah deformasi dihilangkan.Rate this question:

- A.
Batang
- B.
Ladam
- C.

- D.
Jarum
Correct Answer
D. JarumExplanation
The correct answer is "Jarum". The explanation for this is that a compass uses a magnetic needle or "jarum" to align itself with the Earth's magnetic field. The needle is usually mounted on a pivot so that it can rotate freely. One end of the needle is marked with the letter "N" for north, while the other end is marked with the letter "S" for south. As the needle aligns itself with the Earth's magnetic field, it points towards the Earth's magnetic north pole, allowing us to determine the direction of north.Rate this question:

- D.
Rem sepeda
Correct Answer
D. Rem sepedaExplanation
The correct answer is "Rem sepeda" because it is the only object listed that utilizes frictional force. When the brakes of a bicycle are applied, the brake pads create friction against the wheel rims, causing the bicycle to slow down or stop. This frictional force is essential for controlling the speed and movement of the bicycle. The other objects listed, such as an arrow, slingshot, and compass, do not rely on friction to function.Rate this question:
