Answer:
The approximate change in entropy is -14.72 J/K.
Explanation:
Given that,
Temperature = 22°C
Internal energy
Final temperature = 16°C
We need to calculate the approximate change in entropy
Using formula of the entropy
Where, = internal energy
T = average temperature
Put the value in to the formula
Hence, The approximate change in entropy is -14.72 J/K.
Answer: x = 73
Explanation:
Firstly, arithmetic mean is the average of the set of numbers given in question while median is the number that is placed at the middle of sets of distribution after been arranged in either ascending or descending order.
According to the question the mean will give us sum total of the number divided by the total numbers given i.e
63 + 67 + x + 80 + 82/5
Since the numbers are already listed in increasing order, median will be 'x'
Since the arithmetic mean is equal to the median according to the question, we then have;
63 + 67 + x + 80 + 82/5 = x
Cross multiplying we have;
63 + 67 + x + 80 + 82 = 5x
292+x = 5x
292 = 5x - x
292 = 4x
x = 292/4
x = 73
Answer:
Distance, d = 299.8 meters
Explanation:
Given that,
Speed of light,
Time,
We need to find the distance covered by the light in this time. It can be calculated as :
d = 299.8 meters
So, the distance covered by the light is 299.8 meters. Hence, this is the required solution.
Answer:
Sinkhole lakes in Florida typically occur in areas with a thin layer of soil overlying limestone, hi areas with impermeable clay soil, a lake might be perched (the lake level is maintained naturally above groundwater level, Fig. 3). The shapes of sinkhole lakes often show how they are formed....

Well a simple answer would be it would start to melt because icecream is a liquid unless its frozen,just like ice.
