Answer:
Change in entropy is 0.8712 kJ/kgK
Given:
Initial Temperature, T = 320 K
Initial Pressure, P = 130 kPa
Final Pressure, P' = 438 kPa
Solution:
Here, a rigid tank is considered, therefore, the volume of the tank is constant and for a process at constant volume:
Pressur, P ∝ Temperature, T
Therefore,
Now, change in entropy is given by:
Therefore, change in entropy is 0.8712 kJ/kgK

The switch has been in position a for a long time. At t = 0, the switch moves from position a to position b. The switch is a make-before-break type so there is no interruption of the inductor current. a. Find the expression for i(t) for t ≥ 0. b. What is the initial voltage across the inductor after the switch has been moved to position b? c. Does this initial voltage make sense in terms of circuit behavior? d. How many milliseconds after the switch has been put in position b does the inductor voltage equal 24V? e. Plot both i(t) and v(t) versus t

well my bff is trans so yes I guess xd
Answer:
water sample have more water content
Explanation:
given data
soil 1 is saturated with water
unit weight of water = 1 g/cm³
soil 2 is saturated with alcohol
unit weight of alcohol = 0.8 g/cm³
solution
we get here water content that is express as
water content = ....................1
here soil is full saturated so is 100% in both case
so put here value for water
water content = 100 % × 1
water content = 1 g
and
now we get for alcohol that is
water content = 100 % × 0.8
water content = 0.8 g
so here water sample have more water content
