Answer:
<h3>
The volume needed to expand the gas is = 11 Lit = 11000 </h3>
Explanation:
Given :
Initial volume Lit.
Energy J = 9.38 Lit × atm. ⇒ ( 1 Lit×atm. = 101.325 J )
Pressure 650 torr = 0.855 atm. ⇒ ( 1 torr = 0.00132 atm )
In this example we have to be aware of unit conversion system.
From the laws of thermodynamics,
Here in this example, all the energy of combustion is converted into work to push back the piston
Lit =
Answer:
the speed of the fluid in the wider section of the pipe is 1m/s.
Explanation:
By equation of continuity we can write (for ideal (non-viscous, in-compressible).
A_1,A_2 are areas of the pipe at inlet and outlet of the pipe.
_1
Here, d_1 , d_2 are diameters of inlet and outlet, also v_1, v_2 are velocities at inlet and outlet.
putting values we get
solving we get
5m
Explanation:
Given parameters:
Energy = 35J
Force on object = 7N
Unknown:
Distance moved = ?
Solution:
The energy on the car will cause the car to do work . When work is done, a force moves a body in particular distance. We can see that energy and force are related:
Energy = force x distance
Distance =
Inputting the parameters:
Distance = = 5m
