Drones do not hover in one place because they are affected by external factors such as wind, air currents, and changes in air pressure. These factors can cause the drone to drift or move around even when the pilot is trying to keep it in one position. Additionally, the drone's internal sensors and GPS system may not be able to maintain a perfectly stable position, leading to small movements and adjustments in its hovering. Overall, the combination of external influences and limitations in the drone's technology prevent it from hovering in one place with absolute precision. **

To calculate the volume of the aquarium in liters, we need to multiply the length, width, and height in centimeters and then divide by 1000 to convert to liters. Volume = 120cm x 40cm x 55cm = 264,000 cm³ Converting to liters: 264,000 cm³ ÷ 1000 = 264 liters Therefore, 264 liters can fit in an aquarium with dimensions length 120cm, width 40cm, and height 55cm. **
