The correct statements are that the speed decreases as the distance decreases and speed increases as the distance increases for the same time.
Answer:
Option A and Option B.
Explanation:
Speed is defined as the ratio of distance covered to the time taken to cover that distance. So Speed = Distance/Time. In other words, we can also state that speed is directly proportional to the distance for a constant time. Thus, the speed will be decreasing as there is decrease in distance for the same time. As well as there will be increase in speed as the distance increases for the same time. So option A and option B are the true options. So if there is decrease in the distance due to direct proportionality the speed will also be decreasing. Similarly, if the distance increases, the speed will also be increasing.
Answer:
Explanation:
Here by ideal gas equation we can say
now we know that pressure is kept constant here
so we will have
since we know that number of moles and pressure is constant here
so we have
now we know that initial temperature is 17.8 degree C
and finally volume is doubled
So we have
so final temperature will be
