<span>Most objects tend to contain the same numbers of positive and negative charge because this is the most stable situation. In fact, if an object has an excess of positive charge, it tends to attract an equal number of negative charges to balance this effect and restore neutrality: the attracted negative charges combine with the excess of positive charges, leaving the object electrically neutral.</span>
The stretch of the spring is
The constant of the spring is k=15 N/m, so we can find the force produced by the weight by using Hook's law:
This
is
true
Electromagnetic waves travel fastest through vacuum
The answer is True
Fiber is an example
Answer: No
Explanation:
The force F required is equal to the Force exerted in stretching the first material since conditions are the same
