So it can be easily absorbed into the blood steam.
Answer : The temperature will be, 969.66 K
Explanation :
Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.
![P\propto T](https://tex.z-dn.net/?f=P%5Cpropto%20T)
or,
![\frac{P_1}{T_1}=\frac{P_2}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7BP_1%7D%7BT_1%7D%3D%5Cfrac%7BP_2%7D%7BT_2%7D)
where,
= initial pressure of gas = 758 torr
= final pressure of gas = 2500 torr
= initial temperature of gas = ![21.0^oC=273+21.0=294K](https://tex.z-dn.net/?f=21.0%5EoC%3D273%2B21.0%3D294K)
= final temperature of gas = ?
Now put all the given values in the above equation, we get:
![\frac{758torr}{294K}=\frac{2500torr}{T_2}](https://tex.z-dn.net/?f=%5Cfrac%7B758torr%7D%7B294K%7D%3D%5Cfrac%7B2500torr%7D%7BT_2%7D)
![T_2=969.66K](https://tex.z-dn.net/?f=T_2%3D969.66K)
Thus, the temperature will be 969.66 K
Answer:
a) 70,560 J
b) 88.2 N/m
Explanation:
The spring potential will equal the change in gravity potential
PS = PE = mgh = 80(9.8)(100 - 10) = 70,560 J
PS = ½kx²
k = 2PS/x² = 2(70560)/(100 - 50 - 10)² = 88.2 N/m
Answer:
f = 878,080 N
Explanation:
mass of pile driver (m) = 2100 kg
distance of pile driver to steel beam (s) = 5 m
depth of steel driven (d) = 12 cm = 0.12 m
acceleration due to gravity (g0 = 9.8 m/s^{2}
calculate the average force exerted on the pile driver by the beam.
- from work done = force x distance
- work done = change in potential energy of the pile driver
- equating the two equations above we have
force x distance = m x g x (s - d)
f x 0.12 = 2100 x 9.8 x (5- (-0.12))
d = - 0.12 because the steel beam went down at we are taking its
initial position to be an origin point which is 0
f = ( 2100 x 9.8 x (5- (-0.12)) ) ÷ 0.12
f = 878,080 N
