An extension cord can be plugged into another extension cord by using a multi-outlet adapter or a power strip with multiple outlets. Simply plug one end of the first extension cord into the adapter or power strip, and then plug the second extension cord into another available outlet on the adapter or power strip. This allows for the extension cords to be connected in a safe and secure manner, while also providing additional outlets for other devices. It is important to ensure that the total power draw does not exceed the capacity of the extension cords and the outlet. **

The legality of a flight altitude depends on various factors such as air traffic control regulations, airspace restrictions, and the specific flight plan. Pilots must adhere to the altitude restrictions set by air traffic control and comply with any airspace regulations in the area they are flying. Additionally, the aircraft's performance capabilities and the weather conditions also play a role in determining the legal flight altitude. Therefore, without specific details about the flight and the regulations in place, it is not possible to determine the legality of the flight altitude. **

The moon's altitude refers to its angular distance above the horizon. The moon's altitude changes throughout the night as it moves across the sky. At its highest point, the moon's altitude can reach around 90 degrees, which means it is directly overhead. The moon's altitude is an important factor for astronomers and navigators when determining its position in the sky. **

Altitude difference refers to the vertical distance between two points, typically measured from sea level. It is the difference in elevation between the highest and lowest points in a given area. Altitude difference is an important factor in determining the topography and terrain of a region, and it can have significant effects on weather patterns, ecosystems, and human activities such as agriculture and transportation. **

The shorts in the image appear to be Muay Thai shorts. Muay Thai shorts are typically shorter in length and have a wide leg opening to allow for greater freedom of movement during kicks and knee strikes. Additionally, Muay Thai shorts often feature traditional Thai designs and symbols, which can be seen in the image. MMA shorts, on the other hand, are usually longer and have a tighter fit, with more emphasis on grappling and ground fighting. **

The altitude at which one can survive varies depending on factors such as individual health, acclimatization, and the rate of ascent. Generally, humans can survive at altitudes up to around 18,000 feet (5,500 meters) without experiencing severe altitude sickness. However, prolonged exposure to altitudes above 26,000 feet (8,000 meters) without supplemental oxygen is not sustainable for most people due to the lack of oxygen at high altitudes. It is important to acclimatize properly and be aware of the symptoms of altitude sickness when ascending to high altitudes. **

The altitude at which one dies can vary depending on individual factors such as age, health, and acclimatization to high altitudes. However, most people cannot survive for long periods above 26,000 feet (8,000 meters) without supplemental oxygen due to the lack of sufficient oxygen in the air. At extremely high altitudes, the lack of oxygen can lead to altitude sickness, hypoxia, and eventually death. **

Weightlessness occurs at an altitude of approximately 100 kilometers (62 miles) above the Earth's surface, known as the Kármán line. At this altitude, the force of gravity is significantly reduced, allowing objects to float freely without experiencing the sensation of weight. This is the boundary where Earth's atmosphere ends and outer space begins. **
