Answer:
Explanation:
from steam tables , at 250 kPa, and at
T₁ = 80⁰C ⇒ h₁ = 335.02 kJ/kg
T₂ = 20⁰C⇒ h₂ = 83.915 kJ/kg
T₃ = 42⁰C ⇒ h₃ = 175.90 kJ/kg
we know
according to energy balance equation
A vector of magnitude 2 cannot be added to a vector of magnitude 3 so that the magnitude of the resultant is
1 answer:
<h2>Answer:less than 1 and more than 5</h2>
Explanation:
Vectors are directed physical quantity which also have a magnitude.
When two vectors add,
there are two extreme cases.
Case 1:When both the vectors are in same direction.
In this case,the magnitude is maximum.
The magnitude is given by the sum of individual magnitudes which is .
The maximum possible magnitude is .
Case 2:When both the vectors are in opposite direction.
In this case,the magnitude is minimum.
The magnitude is given by the absolute difference of individual magnitudes which is .
The minimum possible magnitude is .
