Sadly, I haven't read the chapter, and I can't see Table 3.
But I've seen this fun question before, so instead of reporting
the question for incomplete content, I'm going to answer it
and take your points.
a). one decaration
b). two kilomockingbirds
c). one microphone
d). one nanogoat
e). one examiner
By the way ... perhaps it hadn't occurred to you, but YOU could have
easily answered these completely on your own. All you'd need to do
is take a look at Table 3 in the latest chapter of your Physics book !
Answer:
Part a)
Part b)
Explanation:
Let the length of the rod at 0 degree Celsius is given as Lo
now we have
now we know that
= Length of rod at zero degree C
Part a)
now we have
now we have
Part b)
length of the rod is 6.3689 cm
now we have
Use KE= 1/2mv^2
So...
50,000=(.5)(1,000)v^2
50,000=500 x v^2
Divide 500 on both sides
100 = v^2
Square root both sides to get rid of v^2
Therefore v = 10 m/s
