No. The wavelength of the light determines whether an electron will be ejected from an atom.
yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in. yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in.

Test your hypothesis by Doing an Experiment
The source doesn't care how far you are from it, or whether you're even there, andthere's no relationship between that and the intensity of the radiation it gives off.However, the intensity of the radiation that you receivefrom it is inversely proportionalto the square of your distance from it ... same math as for gravity.
Intensity and duration
The intensity of radiation decreases with distance following an inverse square law. This means that as you move farther away from the radiation source, the intensity decreases exponentially. Therefore, the closer you are to the source, the higher the radiation intensity you will experience.
Paramagnetic molecules have unpaired electrons, while diamagnetic molecules have all paired electrons. One can determine if a molecule is paramagnetic or diamagnetic by examining its electron configuration and counting the number of unpaired electrons. If there are unpaired electrons, the molecule is paramagnetic; if all electrons are paired, the molecule is diamagnetic.
No, the maximum energy is emitted in the direction of motion of a charge. No energy is emitted in the perpendicular direction. The profile of the drop between these two angles is determined by the velocity (especially whether relativistic or not).
Yes, the intensity of X-rays and gamma rays can differ. Gamma rays typically have higher frequencies and energies than X-rays, so they can be more penetrating and have a higher intensity. However, the actual intensity of these radiation types depends on factors such as the source strength and distance from the source.
A redox reaction can be determined by looking at whether there is a transfer of electrons between the reactants. If one substance loses electrons (oxidation) and another gains electrons (reduction), then it is a redox reaction.
You can determine if a molecule is ionic or covalent based on the type of bond it has. Ionic bonds form between a metal and a nonmetal, where electrons are transferred. Covalent bonds form between two nonmetals, where electrons are shared.
It is predominantly the electrons on the outermost shell (valence electrons) of an atom that determine its reactivity with other atoms. These valence electrons are involved in forming chemical bonds with other atoms.
yes it is good and idd apreciate if you would try it it fills so good
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
A 2p orbital does not determine whether a material is a conductor or insulator. Conductivity is determined by the number of free electrons that can move through a material. Materials with many free electrons are typically conductors, while materials with few free electrons are insulators.
