Problem solving is the act of orderly searching for solutions to problem
The correct option that involves approaching a problem in a new way is the option;
Creative thinking
The reasons why creative thinking is the correct option is given as follows;
Finding new ways to approach a problem, involves considering alternatives to already known approaches to the problem
Given that the options to be considered are to be options which have not been applied, then the process does not involve;
Context: Which looks at the variables that relate the problem with setting or circumstance that aid understanding of the problem
Critical thinking; Which is based on the analysis of the known facts, but the new proposals are required
Perseverance; Which involves adherence to a particular option despite delay or difficulty
However;
Creative thinking; Creative thinking involves the consideration of a situation thing or problem in a new way or by approaching a task differently than what was considered a regular approach, which involves finding an unused or imaginative approach to a problem
Therefore;
The option that involves finding new ways to approach a problem is <u>creative thinking</u>

Answer: 3/2mg
Explanation:
Express the moment equation about point B
MB = (M K)B
-mg cosθ (L/6) = m[α(L/6)](L/6) – (1/12mL^2 )α
α = 3g/2L cosθ
express the force equation along n and t axes.
Ft = m (aG)t
mg cosθ – Bt = m [(3g/2L cos) (L/6)]
Bt = ¾ mg cosθ
Fn = m (aG)n
Bn -mgsinθ = m[ω^2 (L/6)]
Bn =1/6 mω^2 L + mgsinθ
Calculate the angular velocity of the rod
ω = √(3g/L sinθ)
when θ = 90°, calculate the values of Bt and Bn
Bt =3/4 mg cos90°
= 0
Bn =1/6m (3g/L)(L) + mg sin (9o°)
= 3/2mg
Hence, the reactive force at A is,
FA = √(02 +(3/2mg)^2
= 3/2 mg
The magnitude of the reactive force exerted on it by pin B when θ = 90° is 3/2mg
Answer:The simplify command is used to apply simplification rules to an expression. The simplify routine searches the expression for function calls, square roots, radicals, and powers and invokes the appropriate simplification procedures. For detailed information on the simplify command, see simplify/details.

Answer:
Input Power = 6.341 KW
Explanation:
First, we need to calculate enthalpy of the water at inlet and exit state.
At inlet, water is at 20° C and 100 KPa. Under these conditions from saturated water table:
Since the water is in compresses liquid state and the data is not available in compressed liquid chart. Therefore, we use approximation:
h₁ = hf at 20° C = 83.915 KJ/kg
s₁ = sf at 20° C = 0.2965 KJ/kg.k
At the exit state,
P₂ = 5 M Pa
s₂ = s₁ = 0.2965 K J / kg.k (Isentropic Process)
Since Sg at 5 M Pa is greater than s₂. Therefore, water is in compresses liquid state. Therefore, from compressed liquid property table:
h₂ = 88.94 KJ/kg
Now, the total work done by the pump can be calculated as:
Pump Work = W = (Mass Flow Rate)(h₂ - h₁)
W = (53 kg/min)(1 min/60 sec)(88.94 KJ/kg - 83.915 KJ/kg)
W = 4.438 KW
The efficiency of pump is given as:
efficiency = η = Pump Work/Input Power
Input Power = W/η
Input Power = 4.438 KW/0.7
<u>Input Power = 6.341 KW</u>
