<h3>
Option A</h3>
In a Series circuit with two identical loads, the voltage across each load will be: the same
<h3><u>
Explanation:</u></h3>
A series circuit is one with total the loads in a row. There is barely ONE path for electricity to pass. If this circuit was a series of flashbulbs, and one left out, the left bulbs would switch off. T
he current in a series circuit is universally the same and the voltage over the circuit is the amount of the unique voltage drops over each component. The voltage referred to as a series circuit is equivalent to the amount of the individual voltage drops.
The Emergency Stop Button icon on the Inputs toolbar can be used to press or release the Emergency Stop button on the CNC machine - False
<h3><u>
Explanation:</u></h3>
The Emergency Stop button is practiced to stop machine operation. When actuated, machine operation terminates instantly. The execution of the part program can be hindered by touching the Control and Spacebar buttons on the computer keyboard. Unlike applying the Emergency Stop button, this way of stopping the milling center does not create the software to drop the path of the tool position.
The Inputs Toolbar is idle. It contributes information only on the state of the Emergency Stop, the safety shield, and the limit switches. An input is active (on) when the button is depressed.
Answer:
a)Percent reduction in area=54.23 %
b)Percent elongation=32.87 %
Explanation:
Given that
Di= 11.53 mm
Df= 7.80 mm
Li= 51.4 mm
Lf= 68.3 mm
A= π/4 D²
a)
Percent reduction in area ,RA
RA= 54.23 %
Percent reduction in area=54.23 %
b)
Percent elongation EL
EL=32.87 %
Percent elongation=32.87 %
Answer:
T=833.8 °C
Explanation:
Given that
m= 2 kg
T₁=200 °C
time ,t= 10 min = 600 s
Work input = 1 KW
Work input = 1 x 600 KJ=600 KJ
Heat input = 0.5 KW
Q= 05 x 600 = 300 KJ
Gas is ideal gas.
We know that for ideal gas internal energy change given as
ΔU= m Cv ΔT
For air Cv= 0.71 KJ/kgK
From first law of thermodynamics
Q = ΔU +W
Heat input taken as positive and work in put taken as negative.
300 KJ = - 600 KJ + ΔU
ΔU = 900 KJ
ΔU= m Cv ΔT
900 KJ = 2 x 0.71 x (T- 200 )
T=833.8 °C
So the final temperature is T=833.8 °C
Answer:
b) False
Explanation:
Work done by a system is not a property because it doesn't define the system's state. Work is mechanical energy exchanged across the system's boundaries.
