So in this problem, we treat the beans as if it's water. From 20°C, we need to bring it down to 0°C at freezing point. The total heat needed for that transformation would be
Q = m(Cp,waterΔT + ΔHfus) = (1.5 lb)(1 kg/2.2 lb)(1000g/1 kg)[(1 cal/g·°C)(20 - 0°C) + 80 cal/g)
Q = 68181.82 cal
Now, we have to equate this to the heat for liquid nitrogen.
Q = mΔHvap
68181.82 cal = m(45 cal/g)
Solving for m,
<em>m = 1,515.15 g or 3.33 pounds of liquid nitrogen</em>
The expression " middle name" initially showed up in a 1835 Harvard University magazine called Harvardiana, yet the practice goes back much further.
In extremely old Rome, having many names was a respect, typically given the most imperative individuals - like Gaius Julius Caesar. The brief premium ceased to exist just to lift move down again in Western societies in the 1700s, when rulers/rich and capable individuals began giving their youngsters wonderfully long names to demonstrate their place in (group of individuals/all great individuals on the planet). (in nearly a similar way), long Spanish and Arabic names embrace father-in light of other-based names from past eras to follow the individual's family tree. (In different societies, similar to Chinese, there are as a rule/(previously) no middle names. :)

Answer:
speed of the spaceship is 0.495251 c
Time T = 1.4982 hr
Explanation:
given data
length L1 = 1600 m
length L2 = 1390 m
to find out
speed of the spaceship and time
solution
we know here
L2 = L1 × 
so we find V by put L1 and L2
1390 = 1600 ×
V = 0.495251 c
speed of the spaceship is 0.495251 c
and
we know T1 = 1.95 hr
so we find T2
T1 = T2 
put here V and T1 so we get T2
1.95 = T2 
Time T = 1.4982 hr
