Explanation:
According to hooks law "provide the elastic limit of an elastic material is not exceeded the extension e is directly proportional to the applied force F"
where F= applied force
k= spring constant
e= extension
Given data
length of string l = 16cm
extension e = 20-16= 4cm
applied force = 5N
we need t o first calculate the spring constant k
apply the formula
we can now calculate the extension of the string when supporting a 6N weight
The length of the string when supporting a 6N weight is
<em>COMMENT </em><em>:According to the analysis an extra weight of 1N will cause add 0.8cm to the length of the string</em>
Answer:
Ions compounds can be described as compounds which can dissociate into ions. An ionic compound is usually made from a metal atom and a non- metal atom. This means that a positively charged atom joins with a negatively charged atom to make the ionic bond.
For example, consider sodium chloride. Sodium has the positive charge whereas chlorine has the negative charge. Both the atoms join by ionic bonding.
