An ideal gas is taken through a cyclic thermodynamic process through four steps. The amounts of heat given to the system in thes
e steps are Q{1} = 1000J, Q{2} = - 800J, Q{3} = 450J , Q{4} = - 200 J respectively. The efficiency of cycle is nearly

Answer:
3 volts
Explanation:
Number of turns in primary coil = = 100
Number of turns in secondary coil = = 200
Voltage across primary coil = = 1.5 volts
Voltage across secondary coil = = ?
In a transformer, the ratio of number of turns of primary to secondary coil is equal to the ratio of the respective voltages i.e.
Using the given values, we get:
Thus, the voltage measure across secondary coil would be 3 volts
Answer:
Explanation:
Here at thermal equilibrium we can say that thermal energy given by Hot coffee is equal to the thermal energy absorbed by ice cubes
So here we have
now since ice cubes are added into coffee when it is at melting temperature
So here we can say that final temperature of coffee is T degree C
Now we have
here we have
L = 333 kJ/kg = 333 J/g[/tex]
now we have
