Step-by-step explanation:
In the plane geometry Abeka, second edition, it is given :
Principle 2 states that between any two points, only one straight line can be drawn.
And according to principle 3 two straight lines interacts at one point only.
Thus this can be well illustrated by two straight lines which are represented by the streets of a city and these two streets intersects at a point.
To start this question, we should know what is the atomic number of cobalt. The atomic number (the number of protons) of Cobalt is Z =27.
Now, we know that a Cobalt 60 isotope means an isotope of Cobalt whose Atomic Mass is 60.
Thus, in a Cobalt 60 isotope, the number of neutrons in the nucleus are

From the question we know that the given nuclear mass is 59.933820 u.
Now, the mass defect of Cobalt 60 can be easily calculated by adding the masses of the protons and the neutrons as per our calculations and subtracting the given nuclear mass from it.
Thus,
Mass Defect = (Number of Protons Mass of Proton given in the question) + (Number of Neutrons Mass of Neutron given in the question)-59.933820 u

Thus, the required Mass Defect is 0.5634u.
In eV, the Mass Defect is 
Answer:

Answer:
is the equivalent expression as
is equal to
.
Step-by-step explanation:
Considering the expression

As we know that
- Like terms are said to be the terms which hold the same variables raised to the same power.
- For example,
and
are like terms as they contain the same variable
raised to the same power.
Lets solve the expression





Therefore,
is the equivalent expression as
is equal to
.
