(4) a compound is the correct answer~
Yes, the ones that make of the atom itself. The proton which is a positive charge which has most of the weight of the atom and is found in the nucleus. The neutron which weighs almost nothing has a neutral charge and is found in the nucleus with the protons. Lastly the electrons which have a negative charge and orbit the atom in the electron cloud around the nucleus and also weigh very little.
When, in a solid state, molecules are vibrating in place, in a liquid state, molecules are moving fast, and in a gas state, molecules are moving very fast.
The correct answer is D. Frequency. I just took the test.
Answer:
Gamma range
Explanation:
A very intense start is a bright star at very high temperature. Now, hotter the object shorter is the wavelength of peak radiation. The increasing order of wavelength of the given regions in the electromagnetic spectrum are:
gamma range < ultra violet < visible < infrared
Ideally, since the shortest wavelength based on the given options is the gamma range, the peak intensity can also be expected to fall at that wavelength. If the star spectrum was recorded in the UV-visible range of the EM spectrum, then it would fall in the UV range
