Based on N:Z ratio, Zr-85 is expected to decay by positron emission. Zr-95 is expected to emit beta particles in a beta decay.
The N:Z ratio determines the stability of a nucleus. If a nucleus has N:Z ratio >1.5 or <1.0, such a nucleus is unstable and will undergo radioactive decay. The aim of such a decay is to attain a favorable N:Z ratio.
For Zr -85, the N:Z ratio is 1.1 while the N:Z ratio of Zr-95 is 1.4. Zr -85 is expected to decay by positron emission which increases the N:Z ratio. For Zr-95, the nucleus tends to undergo processes that decrease the N:Z ratio such as beta emission.

Answer:
Velocity
Explanation:
In the context of speed, this refers to the change of position in a fixed amount of time, and velocity provides more depth to that; it also gives direction, which makes sense when you eventually learn that the velocity is the derivative of the position.
In physics, velocity is prevalently used.
Answer:
Did not understand your question
Explanation:
All I know is that:
Control variable is what you keep the same throughout all of the tests.
Dependant variable is what you observe from the test
Independent variable is what you are altering in the test

Answer:
MM/n will be less than the theoretical value
Explanation:
Provided that
The plating efficiency is proportional to the element weight
i.e.
That represents
So,
MM by N value is
= 65.39 g /mol ÷ 2
= 32.70 g/mol
Also, the experimental plating value is 0.55 that represents that it is much lesser than the normal value
So it would be concluded that the MM by N would be lower than the theoretical value
