Heat rises therefore the heat from the fire rises up to your hand... i didnt have any answer choices to work with sorry
Answer:
the ratio of the kinetic energy of an electron to that of a proton if their wavelengths are equal is 1835.16 .
Explanation:
We know, wavelength is expressed in terms of Kinetic Energy by :
Therefore , 
It is given that both electron and proton have same wavelength.
Therefore,
.... equation 1.
.... equation 2.
Now, dividing equation 1 by 2 .
We get ,
Putting value of mass of electron = 
and mass of proton = 
We get :
Hence , this is the required solution.
Answer:
45°.
It is a property of the parabolas.. When the angle between a parabola and the x-axis is 45° the range is maximum.
Each electron provides a charge of -1.602 × 10^-19 coulombs.
If there are 8.51 × 10^-6 extra electrons:
1 electron ____________ -1.602 × 10^-19 coulombs
8.51 × 10^6 electrons___x = -1.602 × 10^-19*8.51 × 10^6/1=-1.32×
10^-12 coulombs
So the extra electrons provide a charge of 1.32× 10^-12
coulombs.
So the net charge is -1.32× 10^-12 coulombs (there are more
electrons besides those extra electrons, but there are also protons, so they
don’t affect the net charge – the other electrons just compensate the charge of
the protons).
Answer:
Atoms form chemical bonds to satisfy the Octet rule and become Stable element.
Explanation:
- Every atom desires to achieve total eight valence electron in their outermost shell to become stable. This rule is known as octet rule.
- During the chemical reaction process, every element goes through the process of receiving or donating the element to complete the octet rule to become stable.
- The electronic configuration of element having eight electrons in its valence shell is the noble gases.
