Answer:
707 m/s
Explanation:
Since the root mean temperature is directly proportional to the root mean square velocity.
We have
V1/V2 =√T1/T2
V1= root mean square velocity of nitrogen at 300K
V2= root mean square velocity of nitrogen at 600K
Thus;
517/V2 = √300/600
517/V2 = 0.707
V2 = 500/0.707
V2= 707 m/s

Answer:
Explanation:
14 lb force is required to stretch the spring by 4 inch distance
So we have
stretch in the spring is given as
now we will have
Now we need to find the work to stretch it by x = 10 in = 0.254 m
so we have
