Ans:
a = 9i + 12j
b = 3i + 4j
Explanation:
We have two equations:
<span>a - b = 2c --- (A)
</span><span>a + b = 4c --- (B)
and two unknowns:
a = ?
b = ?
Whereas,
c = 3i + 4j
Add equations (A) and (B):
=> a - b = 2c
a + b = 4c
----------------------
2a = 6c
=> a = 3c --- (C)
Put the value of vector c in equation (C):
(C) => a = 3(3i + 4j)
=> a = 9i + 12j
Now that we have vector a, put that vector and vector c in equation (A):
(A)=> (9i + 12j) - b = 2(3i + 4j)
=> b = (9i + 12) - (6i + 8j)
=> b = 3i + 4j
Ans:
a = </span>9i + 12j
b = 3i + 4j<span>

Answer:0.0909 kJ/K
Explanation:
Given
Temperature of hot Reservoir 
Temperature of cold Reservoir 
Heat of 100 kJ is transferred form hot reservoir to cold reservoir
Hot Reservoir is Rejecting heat therefore 
Heat is added to Reservoir therefore 
Entropy change for system



As entropy change is Positive therefore entropy Principle is satisfied
Answer:
yes
Explanation:
When all of the molecules (or atoms) in a system stop moving completely, that's as cold as they can get
