Answer:
The time is 1206 years.
Explanation:
Given that,
Distance = 27000 ly
Speed = 0.9990c
We need to calculate the time
Using formula of speed
Put the value into the formula
We need to calculate the time dilation the clock on the spaceship
Using formula of dilation time
The time convert in years
We know that,
So, the time is
Hence, The time is 1206 years.
In <u>370 K to 375 K </u>temperature intervals of 5 K, would be the greatest increase in the entropy of the sample.
Option: C
<u>Explanation</u>:
Because the largest difference in molar entropy occurs when a condensed phase (solid/liquid) transforms to the gas phase. Then change in entropy is equal to heat transfer divided by temperature: .
According to given ice sample at 260 K, when this solid sample start converting into liquid sample it will gain positive temperature and steam will take place near 373 K (273 K ice temperature + temperature of boiling water). Therefore it’s very obvious that greatest increase in entropy will occur during 370 K – 375 K.
