试题 :
1(a)What is the first law of thermodynamics,for
W=p△V?
(b)What is the internal energy of the H2 gas
at temperature T?
(c)What is the specific heat of the H2 at con-
stant volume?
(d)By ideal gas equation of motion,what is the
work done,at constant pressure,for an increase
of temperature △T of H2?
(e)What is the specific heat at constant press-
ure of H2?
2(P402 Problem 15-27) a block weighing 14.0N,which can slide without
friction on an incline at angle θ=40.0ο,is conn-
ected to the top of the incline by a massless s-
pring of unstretched length 0.450m and spring c-
onstant 120N/m.(a)How far from the top of the i-
nclineis the block’sequilibrium point?(b)If the-
block is pulled slightly down the incline and re-
leased,what is the period of the resulting oscillations?
3(Problem14-53)the fresh water behind a reservoir dam has dep-
th D=15m. A horizontal pipe 4.0cm in diameter passes
through the dam at depth d=6.0m. A plug secures the
pipe opening.(a)Find the magnitude of the frictional
force between plug and pipe wall.(b)The plug is removed.
What water volum exits the pipe in 3.0h?
4( Sample Problem 12-4 )See the textbook”Fundanmental of Physics7Ext V.”
