Silver-109 has a mass of 109 amu. It is one of the isotopes of the silver atm.
<h3>What are isotopes?</h3>The term isotopes has to do with the atoms of the same element that has the same atomic number but different mass numbers. This implies that the isotopes that we have do have the same number of protons but they do not have the same number of neutrons and the fact that they differ in the number of neutrons implies that would have the same chemical property.
We can see from the question that there are two isotopes of silver and tehse isotopes of silver have been identified as silver-107 and silver-109. The isotopes do have the same mass and not the same number of protons.
The percentage abundance of the two isotopes are not the same which means that one is more than the other. We can now see that the mass of the silver 109 in amu is 109 amu.

Answer:
122.5 Joule, or 122.5 j
Explanation:
Given,
mass of the object (m) = 5 kg
velocity of the object (v) = 7 m/s
Kinetic energy = × m × v²
Applying the formula:
Kinetic energy = × 5 × 7²
⇒ × 5 × 7 × 7
⇒
⇒ 122.5 Joule, or 122.5 j
Kinetic energy is the energy that an object gains as the result of the motion. It also depends on the mass of the object and force with which the motion is applied. In the given question, the mass of the object is 5 kg and the force of the velocity by which it is moving is 7 m/s.
