Answer:
The answer is C.
Explanation:
An ion is unlike a neutral atom in the fact that it has a charge. Because electrons are negatively charged, an atom becomes more positive if electrons are lost.
I think it’s Malleability
To solve this problem it is necessary to apply the concepts related to uniaxial deflection for which the training variable is applied, determined as
Where,
P = Tensile Force
L= Length
A = Cross sectional Area
E = Young's modulus
PART A) The elongation of the bar in a length of 200 mm caliber, could be determined through the previous equation, then
Therefore the elongaton of the rod in a 200mm gage length is 
PART B) To know the change in the diameter, we apply the similar ratio of the change in length for which,
Where,
Poission's ratio
= Lateral strain
= Linear strain
Therefore the change in diameter of the rod is 
Answer:
Option D => it is moving from high potential to low potential and losing electric potential energy.
Explanation:
Consider a big circle, within the circle we have force, F. That force, F is known as the Electric Field and inside the region or field or space, charged particle or object will be able to exerts force on the other objects.
Electric Field can be represented mathematically by using the formula below; E = kQ/r^2.
So, let us answer the question with what we have considered above. It is worthy of note to know that electric Field moves from a region of higher potential to a region of lower potential. So, any option that says this is correct.
But, there is only one problem and that is the fact that the question asked us about the direction of the movement of proton. Since, proton is s a positive charge, it is going to lose electric potential energy. So, Option D is correct.
Answer:
Explanation:
The total energy of an electron in an orbit consists of two components
1 ) Potential energy which is - ve because the field is attractive
2) Kinetic energy which represents moving electron having some velocity.
Kinetic is always positive.
3 ) In an orbit , The magnitude of potential energy is twice that of kinetic energy. So if -2E is the value of potential energy E wil be the value of kinetic energy.
4 ) Total energy will become some of potential energy and kinetic energy
-2E + E = -E
5 ) So total energy becomes equal to kinetic energy with only sign reversed.
In the given case total energy is -0.28 eV . Hence kinetic energy will be +0.28 eV.
When kinetic energy is calculated as +.28 eV , the potential energy will be
- 2 x .28 or - 0.56 eV .
