Given:
= 323 K
= 293 K
specific heat of aluminium,
specific heat of water,
Formula Used:
Q = m
Solution:
Let the temperature at equilibrium be ' ' K
Now at equilibrium, using the given formula:
Temperature at equilibrium, = 295.513 K
Now, change in entropy(in J/K) is given by:
Q = m
= 12094.28 cal
Now,
= 40.93 cal/K = 9.78 J/K
Therefore change in entropy is given by:
Answer:
402 nm .
Explanation:
Let the wave length of unknown light be λ .
For fifth order maxima the condition is
path difference at the point of fringe = 5 λ
For red light of 670 nm , for 3 rd order maxima
path difference at the point of fringe = 3 x wave length
= 3 x 670 nm
From these two equations
5 λ = 3 x 670 nm
λ = 3 x 670 / 5 nm
= 402 nm .
Answer:
3) Dims in, Brightens out
Explanation:
The relationship between the inductance of a coil and the current is inverse.
As the rod is thrusted into the solenoid, the inductance increases, which in turn decreases the current and the bulb gets dimmer. This is also because some magnetic force is drawn away from the solenoid and the battery.
When the rod is removed, the inductance of the solenoid decreases, the current increases, and the bulb becomes brighter.
Answer:
The images output from your new color laser printer seem to be a little too blue. to fix this problem we need to calibrate the printer.
Explanation:
This can be done by opening the toolbox, clicking in the device setting folder their you get print quality page click on it. Under the print quality option click on the calibrate next to calibrate now. Then click OK unless when the 'your request has been sent to the device' appears on the screen. When the calibration ends again try printing. calibrating is useful for managing the proper alignment of the inkjet cartridge nozzle to the paper and each other, without proper calibration the print quality deteriorates.
Answer:
The temperature on 16th August is 23.37 degree Celsius.
Explanation:
In Los Angeles, the temperature at 3:00 p.m on Aug 16th is 73.9 °F. It is required to convert it into degree Celsius.
The conversion from Fahrenheit to Celsius is as follows :
So, the temperature on 16th August is 23.37 degree Celsius.
