Answer:
Period refers to a amount of time needed to complete a cycle, while, on the other hand, frequency is the number of cycles per unit of time. That means that the shorter time between the cycles is, the more cycles there will be. Imagine clapping your hands every two seconds. In ten seconds you would've clapped five times. But if you decrease the period, and clap every second, then in ten secons you would have clapped ten times. So decreasing the period increases the rate.
Another way to look at this is through an equation: T (period) = 1/f (frequency). That means that T•f= 1, which means that if any of them increases, the other must decrease (and vice versa) so that the product of multiplication remains 1.

The actual weight of the stone is 11 N. It is based on the Archimedes principles.
<h3>What is Archimedes principle?</h3>
- Archimedes principle states that the up thrust by water on an object is equal to the weight of water displaced.
- Upthrust by water on an object= actual weight of object - weight inside water
<h3>What is the actual weight of the object, if its weight inside water is 9N and weight of water displaced is 2N?</h3>
Actual weight= weight inside water+ weight of water displaced
= 9N + 2N = 11N
Thus, we can conclude that the actual weight of the object is 11N.
