Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive
Answer:
No
Explanation:
The work that can be turned into heat equals 100% and there is no thermodynamic law that says that cannot be.
<h3><u>Answer;</u></h3>
= 64 N/m
<h3><u>Explanation</u>;</h3>
According to Hooke's Law for a helical spring or an elastic material, extensional force is directly proportional to the distance the material has extended.
F = ke; where F is the extension force, k is the spring constant, and e is the distance extended.
Thus;
k = F/e
= 44N/0.69 m
= 63.768 N/m
<u>= 64 N/m</u>
