Answer:
The final temperature will be 3600 K.
Explanation:
Side 1
T=927°C
T=1200 K
Lets take volume of one side is V then the volume of other side will be 2V. The final volume of system will become 3 V.
The system is closed so the mass of system will remain constant .
We know that for ideal gas P V = m R T
The final pressure is same as initial pressure so we can say that
So the final temperature will be 3600 K.
The power supply isn't connected
Answer:
The deceleration is 4 times higher for 0.5sec than for 2 sec.
Explanation:
If the deceleration happens from 1800deg/sec to zero in 2 sec we have that the magnitude is:
if now the time to decelerate is 0.5sec:
The deceleration is now 4 times higher than the previous situation.
(a) The velocity ratio of the screw is 1570.8.
(b) The mechanical advantage of the screw is 785.39.
<h3>
Velocity ratio of the screw</h3>
The velocity ratio of the screw is calculated as follows;
V.R = 2πr/P
where;
- P is the pitch = 1/10 cm = 0.1 cm = 0.001 m
- r is radius = 25 cm = 0.25 m
V.R = (2π x 0.25)/(0.001)
V.R = 1570.8
<h3>Mechanical advantage of the screw</h3>
E = MA/VR x 100%
0.5 = MA/1570.8
MA = 785.39
