Answer:
is there a graph or something? I will come back to finish this ok. ok
Step-by-step explanation:
Answer:
Area of the square = 36
We can assume that the total area of the 4 circle sections is equal to the area of one circle with a 3 inch radius.
Area of Circle = PI * 3 * 3
Area of white region = 36 - PI * 9
Answer is D
Step-by-step explanation:
The answer is Point K because is -3
$57.75 because 14 divided by .25 is 56 and then plus the first mile is 57.75
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
