The acceleration of each body is determined by its mass and the net force acting on it, according to Newton’s second law of motion. The tension in the string is constant. Each body has the same acceleration, given by 𝑎 = 𝑇 𝑚 = (𝑚 𝑔) − 𝑇 𝑚, where 𝑔 is the acceleration due to gravity.
22 godz. temu · Hubble's law, also known as the Hubble–Lemaître law, is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away from Earth. The velocity of the galaxies has been determined by their redshift, a shift of the light they emit toward the red end of the visible ...
