A nitrogen atom with 7 protons and 8 neutrons has a mass number of 15amu however on the periodic table the atomic mass for nitrogen is 14.01
In mechanics, the normal force<span> is the component, perpendicular to the surface (surface being a plane) of contact, of the contact </span>force<span> exerted on an object . We calculate as follows:
</span>∑F along x = 0 = F - Fn
<span>
Fn = F = mg = 7.52(9.81) = 73.77 N <------OPTION B</span>
<span>The intermolecular attractions are the caause of attraction between the molecules of liquid water. These intermolecular bonding interactions in water is due to Hydrogen bonding. The hydrogen bonding is in between O and H atoms.</span>
Answer:Electrons are transferred in the formation is ionic bonds.
Explanation:Why is because ionic bonds are caused by electrons transferring from one atom to another.
Answer:
There is a decrease in modulus of elasticity
Explanation:
Young's Modulus of elasticity also known as elastic modulus is the deformation of a body along a particular axis under the action of opposing forces along that axis. at atomic levels, it depends on bond energy or strength.
In cold working processes, plastic deformation a metal occurs below its re-crystallization temperature due to which crystal structure of metal gets distorted and as a result of dislocations fractures also occur resulting in hardening of metal but bonds at atomic levels defining elasticity are temporarily affected.
Thus an increase in cold working results in a decrease in modulus of elasticity.
