To maintain a constant temperature, the Earth must radiate as much light energy every second as it absorbs from the Sun. The Earth receives about 1.74 x 1017 W from the Sun, and absorbs about 70% of the incoming light, reflecting 30% of it back into space. That 70% is the light energy that must be re-radiated by the Earth. The Earth's total surface area is about 5.10 x 1014 m2. If the Earth radiates as a uniform, perfect blackbody, what must its temperature be in order to radiate as much light energy every second as it receives from the Sun

What are atoms of the same element with varying number of neutrons

When temperature of a substance increases, of its particles increase resulting in more between particles. real world applications of thermal expansion absolute zero (-273 degrees c) is the lowest possible temperature on the kelvin scale. it is a measure of where a substance has no kinetic energy. heat is a process of the . energy flows spontaneously from a object to a until equilibrium is reached. heat is measured in heat is transferred throughis a method of heat transfer that occurs between particles of matter that are in direct contact with each other. are poor conductors that impede / reduce the rate of heat transfer. is a method of heat transfer that occurs in fluids (non-solids) by means of currents. real world application of convectiona method of heat transfer through electromagnetic waves. when energy moves from one object to another inside a closed system, no energy is or in the system in the transaction. systems will spontaneously move to a state of organized energy or high disorder over time called

Estimate the schwarzschild radius (in kilometers) for a mini-black hole formed when a superadvanced civilization decides to punish you (unfairly) by squeezing you until you become so small that you disappear inside your own event horizon. (assume that the your weight is 50 kg)
