To find the amount of oil in each gasoline-oil mixture, we can use the ratio of 1 part oil to 50 parts gasoline. For 5 liters of gasoline-oil mixture, we have 5/51 parts oil, which is 0.1 liters of oil. For 10 liters of gasoline-oil mixture, we have 10/51 parts oil, which is 0.2 liters of oil. For 13 liters of gasoline-oil mixture, we have 13/51 parts oil, which is approximately 0.25 liters of oil. For 26 liters of gasoline-oil mixture, we have 26/51 parts oil, which is approximately 0.51 liters of oil. **

Ruffy doesn't have Gear 1 because it is actually his base form. Gear 1 refers to the initial transformation Ruffy undergoes when he activates his Devil Fruit power, the Gomu Gomu no Mi. This form enhances his physical abilities, such as strength and speed, making him a formidable fighter. As he progresses and develops new techniques, he gains access to more advanced forms like Gear 2 and Gear 3, which further amplify his powers. **

Gear 1 5 typically refers to the first gear in a vehicle's transmission system. The number 5 likely refers to the speed at which the vehicle is traveling while in first gear. This combination suggests that the vehicle is in first gear and traveling at a speed of 5 miles per hour. In general, first gear is used for low-speed driving, such as when starting from a complete stop or navigating through heavy traffic. **

The 5L natural wood stain from Toom is likely toxic if vegetables come into direct contact with it. Wood stains typically contain chemicals that can be harmful if ingested, especially for food items like vegetables. It is important to use food-safe products or finishes when working with surfaces that will come into contact with food to avoid any potential health risks. **

In Formula 1, gear shifting is done using paddle shifters located behind the steering wheel. The driver uses their fingers to pull the right paddle to upshift and the left paddle to downshift. The gear changes are made electronically and are almost instantaneous, allowing for seamless acceleration and deceleration. The gear ratios are pre-set by the team based on the track characteristics to optimize performance. **

Luffy learns Gear 2 during the Enies Lobby arc, specifically during his fight against Blueno. He unlocks this ability after observing CP9's Soru technique and pushing his body to its limits to keep up with Blueno's speed. As for Gear 1, it is not explicitly shown when Luffy learns this technique, but it is implied that he developed it during his training with Silvers Rayleigh during the time skip. Both Gear 1 and Gear 2 are important power-ups for Luffy, allowing him to increase his strength and speed in battles. **

1 * 1 is another way of writing 1 * 1 * 1 because when you multiply a number by 1, the value of the number remains unchanged. In other words, multiplying by 1 does not alter the original number. Therefore, when you multiply 1 by 1, the result is still 1, and when you multiply that result by 1 again, it remains 1. This is why 1 * 1 is equivalent to 1 * 1 * 1. **

Gears with a module of 1 or 2 are typically smaller gears used in precision machinery and equipment. These gears are commonly found in devices where precise and smooth motion is required, such as in watches, small motors, and robotics. Gears with a module of 1 or 2 have finer teeth and are designed to provide more accurate and efficient power transmission in compact spaces. **
