Answer:
Width of a box, 
Explanation:
The ground level energy of a proton in a box is, E = 5 MeV
Energy in a box is given by :
For ground state, n = 1
m is mass of proton
h is Planck's constant
l is width of the box
So, the width of the bx is 
.
Answer: find the answer in the explanation
Explanation:
The capillarity of water molecules is different from the mercury molecules.
What is capillarity ?
This is the tendency of a liquid substance to rise in a capillary tube.
Molecules water rises up in a harrow tubes because of the force of adhesion between the water molecules and the tube molecules is greater than the force of cohesion between the water molecules. This helps water to wet the tube and rise. While mercury which is also a liquid falls in a narrow tubes to level below the outside surface because the force of cohesion between the mercury molecules is greater than the force of adhesion between the mercury molecules and the tube molecules. Mercury does not wet.
As we know that gravitational force of Sun will provide the centripetal force to all planets
so here we will have
here we know that
now from above equation
Yes because it helps with my work
