Answer: TRUE
Explanation:
Atoms are happy when they will not react with other elements while having a full outside ring of electrons because this makes them to be noble.
A stable atom possesses full outside ring of electrons while unstable one does not. So, they are happy also because of stability.
The answer to your question is Metal
No, the speed at which an object falls is not equal to the acceleration at which it falls.
Answer:
Option B
Explanation:
Speed is defined as how fast an object can cover a specific distance and in what time it covers. So it is measured as the ratio of distance covered to the time taken to cover that distance. While acceleration is the rate of change of velocity. Moreover, speed is a scalar quantity and acceleration is a vector quantity. So most of the times, the direction will play an important role in the varying values of speed and acceleration. Also, acceleration of an object will depend upon the force and mass of the object. Thus, speed and acceleration will not attain same value always.
