Answer:
16 rotations.
Step-by-step explanation:
We have been given that Shawn is coasting down a 500 cm long ramp on his inline skates. The wheels on his inline skates are 32 cm in circumference.
To find the number of rotations we will divide length of ramp by 32 as distance covered by wheels in one rotation will be equal to 32 cm.
Therefore, each wheel must make 16 rotations while Shawn is coasting down the ramp.
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
Mass Defect =
Thus, the required Mass Defect is
In eV, the Mass Defect is
Answer:

Answer:
c = 10
Step-by-step explanation:
8² + 6² = c²
64 + 36 = c
64 + 36 = 100
= 10
Hope this helps :)
Answer:
x = 57.59
Step-by-step explanation:
979 * 1 / 17
x = 57.59
cross multiply then divide.
if you want to be thorough and make the equation
17x = 979(1)
x = 57.59
