Answer:
3.5 K
Explanation:
When a sample of a substance releases heat energy, its temperature decreases according to the equation:
where
Q is the heat energy released
m is the mass of the substance
C is the specific heat capacity
is the initial temperature
is the final temperature
For the block of brass in this problem, we have:
m = 0.1 kg is the mass
Q = -56.4 J is the heat energy released (negative since it is released)
C = 380 J/kg K is the specific heat capacity of brass
is the initial temperature
Solving for , we find the final temperature:
Median is the middle data in the list of the given numbers. In the given data set the median gets decreased by the presence of the outlier. Thus, option C is correct.
<h3>What is an outlier?</h3>An outlier is a data that varies significantly from the other data set, due to some error or measuring variability.
The median of the data without outlier is calculated as:
First, data is arranged in the ascending order: 105, 108, 109, 113, 118, 121, 124
Median =
= 4th term
= 113
The median of the data with outlier is calculated as:
First, data is arranged in the ascending order: 61, 105, 108, 109, 113, 118, 121, 124
Median =
= (109 + 113) ÷ 2
= 111
Therefore, the outlier decreased the median.
