A light bulb contains no energy so, Yes, a battery of any size contains more energy than any light bulb.
Yes, a smaller hot object can contain less total energy than a larger cooler object. The total energy of an object is related to its mass and temperature. While the smaller hot object has a higher temperature, its overall energy may still be less than that of a larger object at a lower temperature due to the larger object's greater mass.
Larger.
Smaller galaxies do. Larger galaxies contain billions or even trillions of stars.
The amount of energy in a battery varies depending on its size and type. Common household batteries like AA or AAA typically contain around 1-3 watt-hours of energy, while larger batteries like car batteries can store up to several hundred watt-hours.
Depends on what one means by "smaller". Since sublevels are "inside" or part of the principle energy level, then yes, they are smaller.
The rating mAh is a measure of the amount of energy that can be stored in a battery. The higher the number, the more energy can be stored. Assuming that the batteries are the same physical size and have the same nominal voltage, there is no reason why a 1400mAh battery shouldn't be used in place of a 760mAh. The only difference is that the larger battery will last longer between charges than the smaller one.
The smaller molecule will generally travel faster than the larger molecule since kinetic energy is directly proportional to the mass of the molecule. Smaller molecules have less mass, so they can achieve higher speeds with the same kinetic energy.
Yes, a body of larger mass can be hotter than a body of smaller mass if they are at the same temperature, but this typically refers to their thermal energy content rather than temperature alone. Temperature is a measure of the average kinetic energy of particles in a substance, and if both bodies are at the same temperature, they have the same average kinetic energy per particle, regardless of mass. However, the larger mass body will contain more total thermal energy due to its greater number of particles.
Smaller atoms have higher ionization energy compared to larger atoms because smaller atoms have a stronger attraction between the positively charged nucleus and the negatively charged electrons, making it harder to remove an electron from a smaller atom.
an obtuse is a larger degree than 90 but smaller than 180 degrees.
You are thinking of nuclear fusion, where in the stars hydrogen forms into helium with energy release
The battery with the larger mAh rating will last longer that the battery with the smaller mAh number will last in the same application.
