Destilasi adalah metode pemisahan campuran yang paling tepat untuk memisahkan minyak goreng yang tercampur dengan air. Pada destilasi, campuran dipanaskan hingga mencapai suhu didih minyak goreng, sehingga minyak akan menguap dan dapat dipisahkan dari air. Uap minyak kemudian dikondensasikan kembali menjadi bentuk cair, menghasilkan minyak murni yang terpisah dari air. Metode ini efektif karena minyak dan air memiliki titik didih yang berbeda, sehingga dapat dipisahkan dengan baik melalui destilasi.

The correct answer is 2 dan 3. This is because the question states that the objects have the same mass and are subject to the same force. According to Newton's second law of motion, F = ma, where F is the force, m is the mass, and a is the acceleration. Since the mass is the same for all objects, the object with the largest acceleration will be the one with the smallest inertia or resistance to motion. Therefore, the objects represented by numbers 2 and 3 in the diagram will have the largest acceleration and the highest inertia, respectively.

During expiration, the volume of the chest cavity decreases (4), the intercostal muscles relax (2), the diaphragm relaxes (6), and the air pressure in the chest cavity increases (8). This causes the air to be pushed out of the lungs. Therefore, the correct order of the expiration process in abdominal respiration is 4 - 2 - 6 - 8.

The correct answer is P, R, and Q, S. This can be inferred from the given table that shows the distances traveled by an object in a straight path and within a certain period of time. The object that exhibits both uniform linear motion (GLB) and uniformly accelerated motion (GLBB) would be the one that has traveled distances in both a constant rate and an increasing rate. Looking at the table, the distances for P and R are the same, indicating a constant rate of motion (GLB). On the other hand, the distances for Q and S are different, indicating an increasing rate of motion (GLBB). Therefore, the correct answer is P, R, and Q, S.

Based on the given information, Yumna hears the echo of her own shout after 0.2 seconds and Donny hears the echo of his shout after 0.3 seconds. The speed of sound in air is given as 340 m/s.

We can use the formula: distance = speed x time.

Let's calculate the distance between Yumna and Donny.

For Yumna: distance = 340 m/s x 0.2 s = 68 m
For Donny: distance = 340 m/s x 0.3 s = 102 m

Since both Yumna and Donny are standing in a straight line in front of the cliff, the distance between them is the difference between their distances from the cliff.

Distance between Yumna and Donny = 102 m - 68 m = 34 m

Therefore, the correct answer is 34 m.

When a bullet is shot upwards, it reaches its maximum potential energy at the highest point of its trajectory. The potential energy of an object is given by the formula PE = mgh, where m is the mass of the object, g is the acceleration due to gravity, and h is the height. In this case, the mass of the bullet is given as 60 grams and the acceleration due to gravity is 10 m/s^2. To find the height, we can rearrange the formula as h = PE / (mg). Plugging in the given values, we get h = (60g) / (60 * 10) = g / 10 = 10 / 10 = 1. Therefore, the height of the bullet at its maximum potential energy is 1 meter. However, the answer choices do not include this value, so it seems there may be an error in the question or answer options.
