Answer:
Lower energy shell which will be nearer to the nucleus.
Explanation:
When electron move from one energy level to another, an electron must gain or lose just the right amount of energy.
When atoms releases energy, electrons move into lower energy levels. The electrons in the shells aways from the nucleus have more energy as compared to the electrons in the nearer shells.
Electrons with the lowest energy are found closest to the nucleus, where the attractive force of the positively charged nucleus is the greatest. Electrons that have higher energy are found further away
The force of gravity on objects is proportional to the mass of each object.
(That's a big part of the reason why, when you eat more and your mass
increases, you weigh more.)
The forces of gravity between the Earth and the 6kg ball are 50% greater
than the forces of gravity between the Earth and the 4kg ball.
(The gravitational forces between the 4kg ball and the 6kg ball, or between
both bowling balls and you, are so small that they may be ignored.)
Answer:
Change in specific internal Energy
Explanation:
Given:
- Mass of the gas, m=0.4 lb
- Initial pressure and volume are
- Final pressure and temperature are
- Heat transfer from the gas is 2.1 Btu
Since the process is isotropic we have
So the final volume of the gas is calculated.
Work in any isotropic is given by w
According to the first law of thermodynamics we have
So the Specific Internal Change is given by
So the specific Change in Internal energy is calculated.
<em>A simple metallic band model is proposed for the transition metal mono antimonides, by analogy to the transition metals.</em>
That first one you have selected (3,-3) works in both equations so it's correct.
good job.
you can do this guess and test method with multiple choice answers. If it works in both equations it is the solution. Otherwise use substitution or elimination to combine the two into one equation in only one variable. Then you can solve for the one variable first and use it to solve for the other.
