Answer:
I think is d.
Explanation:
particles that make up the nucleus are balanced. An atom is unstable (radioactive) if these forces are unbalanced; if the nucleus has an excess of internal energy. the Instability of an atom's nucleus may result from an excess of either neutrons or protons.
I'm not sure, but hope it helps.
Forming very strong bond characteristics indicates that an atom is unstable. Hence, option D is correct.

Calculate the acceleration of Josh riding his bicycle in a straight line that speeds up from 4 m/s to 6 m/s in 5 seconds. Initial Speed ____. Final Speed ______. Time ______. Acceleration =________
Answers
Answer:
Initial Speed ____4m/s. Final Speed ______6m/s. Time ______5 seconds . Acceleration =________0.4m/s²
Explanation:
The acceleration is the rate of change of velocity during time t .
acceleration = Final velocity- Initial velocity/ Time
= Vf- Vi/ t
a = Δv/ Δt
= 6m/s- 4m/s/ 5s
= 2m/s/ 5s
= 0.4m/s²
It can also be defined as the difference of the initial and final velocity ( velocities measured in meters per second) during the given time t measured in seconds .The SI unit of acceleration is meter per second squared.
If the velocities are not measured in meters per second or time is not measured in seconds then the units are changed accordingly.

Answers
Answer:
2.60 LExplanation:
The new volume can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
Since we are finding the new volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
From the question we have
[tex]V_2 = \frac{4.31 \times 0.755}{1.25} = \frac{3.25405}{1.25} \\ = 2.60324[/tex]
We have the final answer as
