What is the maximum angle of a pendulum?
Paul Appell pointed out a physical interpretation of the imaginary period: if θ0 is the maximum angle of one pendulum and 180° − θ0 is the maximum angle of another, then the real period of each is the magnitude of the imaginary period of the other.
Answer:
The girl is 2.5 meters below sea level
Step-by-step explanation:
We are told in the question that:
A girl is snorkeling 1 meter below sea level
Hence, her elevation in meters below the sea level = -1m
We are told in the question that:
She then dives down another 1.5 meters
Once again: Her elevation in meters below the sea level = -1.5m
How far below sea level is the girl?
This is calculated as:
-1 m + -1.5m
= -1m - 1.5m
= -2.5m
Therefore, the girl is 2.5 meters below sea level
Answer:
2.71
Step-by-step explanation:
-(1.46) +(_3.82)+7.99= -1.46-3.82+7.99
2.71
Answer:
The conclusion is that the researcher was correct
Step-by-step explanation:
From the question we are told that
The sample size is 
The sample mean is 
The standard deviation is 
The significance level is 
The Null Hypothesis is 
The Alternative Hypothesis is 
The test statistic is mathematically represented as

Substituting values


Now the critical value for
is

This obtained from the critical value table
So comparing the critical value of alpha and the test value we see that the test value is less than the critical value so the Null Hypothesis is rejected
The conclusion is that the researcher was correct
