Answer:
makes a transition from a high to a lower energy state
Explanation:
The emission spectrum is the spectrum of electromagnetic radiation emitted due to the transition from a state of high energy to a state of lower energy made by an electron in the atoms of the chemical element or compound. The emitted photons have an energy equal to the difference in energy between the two states.
yes ,each piece will remain a magnet because the small pieces will cut into north and south
Answer:
The resultant strain in the aluminum specimen is 
Explanation:
Given that,
Dimension of specimen of aluminium, 9.5 mm × 12.9 mm
Area of cross section of aluminium specimen,

Tension acting on object, T = 35000 N
The elastic modulus for aluminum is,
The stress acting on material is proportional to the strain. Its formula is given by :

is the stress

Thus, The resultant strain in the aluminum specimen is
