A body cover 20 kilometre with a speed of 40 km/hand next 20 km with a speed of 30 km per hour calculate average speed |
|
Answer» A body cover 20 kilometre with a speed of 40 km/h time taken, t₁ = 20/40 = 1/2 h It covered NEXT 20 km with a speed of 30 km/h time taken, t₂ = 20/30 = 2/3 h total time taken = t₁ + t₂ = 1/2 + 2/3 = (3+4)/6 = 7/6 h total distance traveled = 20+20 = 40km AVERAGE speed = total distance/total time ⇒ average speed = 40/(7/6) = 40×6/7 ⇒ average speed = 240/7 km/h = 34.28 km/h --------------------------------------------------------------------------- Another shortcut: You see that it travels 20km each time with different speed. When distance travelled each time is same and it travels at speed x and y, average speed can be calculated as: average speed = 2XY/(x+y) using this, average speed = 2×30×40/(30+40) = 34.28 km/h |

What is unsteady state heat transfer ? Explain with a suitable example |
|
Answer» Heat transfer is the transfer of thermal energy from a body, at a high temperature, to another at a lower temperature. This transfer of thermal energy may occur under STEADY or unsteady state CONDITIONS. Under Steady state conditions the temperature within the system does not change with time. Conversely, under unsteady state conditions the temperature within the system does vary with time. |

Why dc series motor should never be started on no load |
|
Answer» This can be seen from the speed-armature CURRENT and the speed-torque characteristics that on low armature current and low torque condition motorshows a tendency to rotate with dangerously HIGH speed. This is the reason why series motor should never be STARTED on LIGHT loads or no loadconditions. |

What is the utility of carry look ahead scheme over the ripple carry scheme |
|
Answer» A SYSTEM of ripple-carry adders is a sequence of standard full adders that makes it possible to add numbers that contain more bits than that of a single full adder. Each full adder has a carryin (Cin) and a carryout (Cout) bit, and the adders are connected by connecting Cout on step k to Cin on step k+1 (Cin on step 0 is C0 in the picture, Cout on step 3 is C4 in the picture) |

Why power factor of semi converter is better than full converter |
|
Answer» An a.c. electrical system has a CHARACTERISTIC line voltage or phase voltage. For example, in your home or office, the phase voltage is 115 volts a.c.; in a factory, the line voltage (as for instance to run a PUMP motor) is usually 460 volts a.c.; and so on. Some power is "single-phase," some is "three phase," and the line and phase voltages are usually differ from ONE another in any case; but your question REGARDS power factors, a matter which does not in and of itself require a discussion of lines, phases and such, so we'll speak no further of those here. |
