Answer: Option (A) is the correct answer.
Explanation:
An isothermal process is defined as the process in which temperature of a system remains constant. In an isthermal process, = 0.
When an outside thermal reservoir is in contact with a system then very slow change in the system will occur in order to allow the system to continue adjusting to the reservoir's temperature through exchange of heat.
Hence, we can conclude that the temperature remains constant, best describes the isothermal process.
Answer:
14.16 W
Explanation:
We have given impedance Z=91.5 ohm
Voltage across the resistor = 36 V
We have to find the power delivered by the source
We know that according to telegens theorem , the absorbed = power delivered
So the voltage across the resistor = 36 V
Current in the RLC circuit this current will be same in the whole circuit as it is a series RLC circuit
Now the power absorbed by the resistor
As the power absorbed = power delivered
So power delivered by the source =14.16 W
Answer:
The magnitude of the force F is given by
F = ( +
+
) *(
*g/(
))
Explanation:
Given there are three blocks of masses ,
and
(ref image in attachment)
When all three masses move together at an acceleration a, the force F is given by
F = ( +
+
) *a ................(equation 1)
Also it is given that does not move with respect to
, which gives tension T is exerted on pulley by
only, Hence tension T is
T = *a ..........(equation 2)
There is also also tension exerted by . There are two components here: horizontal due to acceleration a and vertical component due to gravity g. Thus tension is given by
T =
................(equation 3)
From equation 2 and 3, we get
*a =
Squaring both sides we get
*
=
* (
+
)
*
= (
*
)+ (
*
)
( -
) *
=
*
=
*
/(
-
)
Taking square root on both sides, we get acceleration a
a = *g/(
)
Hence substituting the value of a in equation 1, we get
F = ( +
+
) *(
*g/(
))
