Science is open to change because scientists agree that there are no absolute truths, only the best explanations for the data

-a new model is proposed that fits the data better (such as the heliocentric model of Copernicus)
Answer:
Explanation:
It is a case of oscillation by simple pendulum . Expression for simple pendulum is given as follows
T = 
where T is time period , l is length of pendulum and g is acceleration due to gravity .
, f is frequency of oscillation
For the given case
subsequently length becomes half so
dividing
f = 
frequency of oscillation becomes √2 times.
