Answer:
Isentropic compression in a pump, Constant heat addition in a boiler, Isentropic expansion in a turbine, constant heat rejection in a condenser
Explanation:
Ideal rankine cycle schematic diagram and T-S diagram is shown in below figure
The process 1-2 is isentropic compression is taking place in pump.
The process 2-3 is constant heat addition, heat addition takes places at boiler.
The process 3-4 is isentropic expansion, is taking place is turbine.
The process 4-1 is constant heat rejection , takes place in condenser.
Answer
The current is 0.83 amps .
Option (C) is correct .
Explanation :
Formula for parallel resistors
As given
A combined circuit has two resistors in parallel (10.0 ohms and 14.0 ohms) .
Putting all the values in the above
L.C.M of (10,14) = 70
As given
Another resistors in the series is 5.0 ohms .
Formula
Now by using the ohms law .
Where V is voltage , R is resistance and I is current .
As given
The power source is 9.0 volts .
V = 9 volts
Putting values in ohms law
I = 0.83 amps (Approx)
Therefore the current is 0.83 amps .
Option (C) is correct .
Answer:
Similarities between magnetic fields and electric fields: Electric fields are produced by two kinds of charges, positive and negative. Magnetic fields are associated with two magnetic poles, north and south, although they are also produced by charges (but moving charges). Like poles repel; unlike poles attract.
they attract each other
Explanation:
Since initial velocity is zero hence , u = 0
=> d = 1/2 * a * t2
on solving we get
d = 86.436 metres
Note ; Here Gravitational Acceleration is take as , g = 9.8 m/s2
