Answer:
Conservation of mechanical energy
Explanation:
Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.
In the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved) while the opposite is the case when there is air resistance involved.
One of the chief concerns for those that set sail on the Mayflower was how to organize themselves, especially with a variety of factions, once they got to the new world.

Answer:
1. Cartography
2. Navigational compass
3.Photography
4. Internet
Explanation:
Cartography: is a method of designing, creating and studying geographic locations on flat surfaces like maps. This scientific method dates to some thousands of years ago. It dates to pre-historic times as far back as 2300 BCE when the Babylonians represented locations in clay tablets.
Navigational compass: is thought to have originated in the Han Dynasty in China between the 2nd century BC and the 1st century AD. Then it was used for fortune-telling and was called the "South Pointing Fish." It was adapted as a navigational compass in the Song Dynasty in the 11th century.
Photography: This originated in the 19th century precisely the late 1830's when Nicéphore Niépce captured the pewter plate exposed t light and coated with bitumen. In the later part of the century, geographers began adapting it to their work.
Internet: the inventions of computers in the 1950's came along with the internet that has been a useful resource for geographers.
