9 godz. temu · Google Earth is a computer program that renders a 3D representation of Earth based primarily on satellite imagery.The program maps the Earth by superimposing satellite images, aerial photography, and GIS data onto a 3D globe, allowing users to see cities and landscapes from various angles. Users can explore the globe by entering addresses and coordinates, or by using a keyboard or mouse.
9 godz. temu · Q1.1 The person first moves 70m east and then 30m west. The total distance covered by the person is the sum of these two distances, which is 70m + 30m = 100m. However, displacement is the shortest distance from the initial to the final position of the person. Since the person moved 70m east and then 30m west, the displacement is 70m - 30m = 40m.

It comprises all of existence, any fundamental interaction, physical process and physical constant, and therefore all forms of energy and matter, and the structures they form, from sub-atomic particles to entire galactic filaments.Space and time, according to the prevailing cosmological theory of the Big Bang, emerged together 13.787 ± ...
9 godz. temu · Properties Form and structure Gallium crystals Most metals are shiny and lustrous, at least when polished, or fractured. Sheets of metal thicker than a few micrometres appear opaque, but gold leaf transmits green light. This is due to the electrons which reflect light. Although most elemental metals have higher densities than nonmetals, is a wide variation in their densities, lithium being the ...
