Explanation:
The water molecules begins to leave their fixed position and begins to move as the temperature increases.
When ice melts, it undergoes a state change from solid to liquid and with increasing temperature becomes a gas.
- The basis for this is the increasing movement of the molecules of the water as it transitions from one phase to another.
- In the ice, the molecules are locked and fixed in the lattice
- As the temperature increases, the average kinetic energy of the particles rises.
- This makes the structure of the ice to collapse and forms liquids.
- By the virtue of this, they flow and move over one another
- With increasing temperature, the bonds are broken and vapor forms
The simple harmonic motion not only describes circular movements, also describes waves motion. This makes it fundamental for physics, make us understand waves like sound or light which explains an enormus part of our environment
A) In the case of the Boundary Thickness Layer we use the given formula,
We know as well that,
Re = Número de Reynolds = 
Where,
U = velocity
= kinematic viscosity
For water, kinematic viscosity, 
So, 
B) For flat plate boundary layer. Given the Critical Reynolds Number.= 5*10^5 we know that is equal to Re above.
Thus,
C. Wall shear stress,
For water, dynamic viscosity, 
= 2.344*10^-5 lbf-s/ft^2
Answer: I dont see the option choices
Explanation:
Answer:
The cost of energy is $ 0.34.
Explanation:
The energy is the capacity to do work.
The energy is a scalar quantity and its SI unit is Joule.
The commercial unit of energy is kWh.
Cost of 1 kWh energy = $ 0.17
energy loss by standard window is 2 kWh .
So, the cost of lost of energy is
Cost = $ 0.17 x 2 = $ 0.34
