Calculate the acceleration of gravity on the surface of the sun. the mass of the sun is msun = 1.99 ✕ 1030 kg, the radius of the sun is rsun = 6.96 ✕ 108 m, and g = 6.67 ✕ 10−11 n · m2/kg2. m/s2 (b) by what factor would your weight increase if you could stand on the sun? (never mind that you can't.) fg, sun fg, earth =

Why do scientists believe that light is made of streams of particles? scientists believe that light is made of streams of particles because only the presence of photons can explain phenomena observed during experiments on the photoelectric effect. these observations include only some frequencies of light causing the ejection of electrons, no time gap existing between light striking a metal and electrons being ejected, and intensity having no effect on the kinetic energy of the ejected electrons.

In the image, the arrow is pointing to a celestial object. which attribute disqualifies the object from being a planet?
