The netro level 8 and 4 is the hydrogen atom 2. Hope u enjoy your grade
Answer:
a) increase
Explanation:
The frequency of sound produced due to vibration of a string is governed by the following formula
n = 1/2L√T/m ;
L is length of the string in vibration, T is tension in the string and m is mass of string per unit length.
So frequency is inversely proportional to length of the string. Hence shortning of length of string increases the frequency of vibration.
Answer:
an atom can not be broken into smaller pieces
Explanation:
Because the masses that you give are for blocks that are 1 cubic meter in volume, they also serve as the densities for the two metals that you are comparing.
<span>mass = density*volume </span>
<span>volume = (4/3)*pi*r^3 </span>
<span>volume of iron sphere = (4/3)*3.14*0.0201^3 = 3.40*10^-5 m^3 </span>
<span>mass of iron sphere = 7860* 3.40*10^-5 m^3 = 0.27 kg = mass of Aluminum Sphere </span>
<span>Volume of Al Sphere = 0.27/2700 = 9.90*10^-5 m^3 </span>
<span>Radius = cube root (volume / (4/3) / pi) = 2.87 cm. </span>
<span>I did this using the MS calculator, and I'm not 100% sure on the numerical answer, but the process is what you need to do to solve the problem. You should double check my answer.
hope this helped :)
