5 godz. temu · The physical universe is defined as all of space and time (collectively referred to as spacetime) and their contents. Such contents comprise all of energy in its various forms, including electromagnetic radiation and matter, and therefore planets, moons, stars, galaxies, and the contents of intergalactic space. The universe also includes the physical laws that influence energy and matter, such ...

1 dzień temu · Find p, y and x, as follows: Let p be the part of the root found so far, ignoring any decimal point. (For the first step, p = 0.) Determine the greatest digit x such that (+). We will use a new variable y = x(20p + x). Note: 20p + x is simply twice p, with the digit x appended to the right.
5 godz. temu · The Moon is Earth's only natural satellite.It orbits at an average distance of 384,400 km (238,900 mi), about 30 times the diameter of Earth. Tidal forces between Earth and the Moon have over time synchronized the Moon's orbital period (lunar month) with its rotation period at 29.5 Earth days, causing the same side of the Moon to always face Earth. . The Moon's gravitational pull – and to a ...
