Food and Drink. Fighter pilots do not have any problem taking food and drinks on flights. The biggest concern is to prevent foreign object damage (FOD) from items like crumbs, bottles, bags, etc. Otherwise, there are plenty of places to carry food to eat: your helmet bag, G-Suit pockets and flight suit pockets.
Mercury has less mass than earth,the surface gravity on mercury is less than the surface gravity on Earth.The surface gravity on Mercury is about 38% of the surface gravity on Earth,so that means if you weighed 100kg then you would only be 38kg on Mercury.
If you're talking about the entire planet together, then of all the planets in our solar system, earth is the most dense. Rock planets are obviosly denser than gas giants, and the largest rock planet is earth, making it have the most gravity, which causes it to be the most condensed and have the highest density. The Earth is the densest planet in the Solar System overall. It has a density of about 5.515 times that of water. However, it is only the densest because it is made of rocky material AND massive enough for that material to be compressed more under its own gravity and internal pressure. If it were not for gravitational compression, Mercury would actually be denser than the Earth.
