Therefore, recycling is an important solution to mitigate the negative impacts of plastic waste on the environment and human health.

The correct answer is 3 : 2. The explanation for this answer lies in the concept of potential energy. The potential energy of an object is directly proportional to its mass and height. In this case, both fruits have the same height since they fell from the same tree. However, fruit A has a higher mass than fruit B. Therefore, fruit A will have a higher potential energy compared to fruit B. The ratio of their potential energies can be calculated by dividing the mass of fruit A by the mass of fruit B, which gives us 3 : 2.

The frequency of an object's vibration is calculated by dividing the number of vibrations by the time it takes to complete those vibrations. In this case, the object vibrates 25 times in 5 seconds, so the frequency is 25/5 = 5 Hz. The period of an object's vibration is the time it takes to complete one full vibration. In this case, since the frequency is 5 Hz, the period is 1/5 = 0.2 seconds. Therefore, the correct answer is 5.0 Hz and 0.2 s.

The correct answer is (1) dan (4). This is because statement (1) states that the direction of propagation of sound is the same as the direction of its vibrations, which is true. Statement (4) states that sound is produced by vibrating objects, which is also true. Statement (2) states that sound becomes louder as its frequency increases, which is incorrect. Statement (3) states that sound cannot propagate through solids, which is also incorrect.

The correct answer is 1-4-5-7. This is the correct sequence of events during expiration in the respiratory process. First, the intercostal muscles relax (1), then the volume of the chest cavity decreases (4), leading to an increase in air pressure in the lungs (5). Finally, the air in the lungs is expelled (7).

When two substances with different temperatures are mixed together, they reach a final temperature called the equilibrium temperature. This can be calculated using the principle of heat transfer, which states that the total heat gained by one substance is equal to the total heat lost by the other substance. In this case, the first substance is 2 kg of water at 100ºC, and the second substance is 5 kg of water at 30ºC. By applying the heat transfer principle, we can calculate that the final temperature of the mixture will be 50ºC.

The correct answer is 819 kJ because to calculate the heat required in the process, we need to consider the heat required to raise the temperature of the ice from its initial temperature to 0°C, the heat required to melt the ice at 0°C, and the heat required to raise the temperature of the resulting water from 0°C to its final temperature. By using the specific heat capacities and latent heat of fusion given, we can calculate that the total heat required is 819 kJ.

The fan uses more electricity than the lamp but less than the electric kettle. The electric kettle uses the most electricity out of the three appliances.

The correct answer is 1.600 N. This is because the force required to lift an object is equal to its mass multiplied by the acceleration due to gravity. In this case, the mass of the object is 400 kg and the acceleration due to gravity is 10 N/kg. Therefore, the force required to lift the object is 400 kg * 10 N/kg = 4,000 N. However, since the question asks for the force required to lift the object to the top, which is against gravity, the force needed will be double that amount, resulting in 4,000 N * 2 = 8,000 N. However, the question only provides answer choices in the hundreds, so the closest option is 1,600 N.

The correct answer is 2 dan 4. This is because in the image, there are two objects interacting with each other. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. In this case, object 2 is exerting a force on object 4, and object 4 is exerting an equal and opposite force on object 2. This is a clear example of Newton's third law in action.

The correct answer is "keluamya darah menstruasi sudah berhenti" because the thickening of the uterine wall occurs after the menstrual bleeding stops. During the menstrual cycle, the uterine lining sheds through menstruation, and once this bleeding stops, the uterus begins to rebuild its lining in preparation for a potential pregnancy. Therefore, the thickening of the uterine wall starts after the cessation of menstrual bleeding.

The peti besi that has the highest acceleration is the one being pushed by one child. This is because when only one child is pushing the box, all the force exerted by the child is applied to that box, resulting in a larger net force and therefore a greater acceleration. When multiple children are pushing the other boxes, the force is divided among them, resulting in a smaller net force and a lower acceleration.
