which plate boundary type doesn't destroy or produce lithospheric material
Answers
The plate boundary type that does not destroy or produce lithospheric material is a transform boundary.
At transform boundaries, two tectonic plates slide past each other horizontally, in opposite directions or in the same direction but at different speeds. Transform boundaries are characterized by intense shearing forces and can cause earthquakes as the plates lock and then release, allowing them to slide past each other.
Unlike divergent boundaries (where new lithospheric material is created as plates move apart) and convergent boundaries (where lithospheric material is destroyed as plates collide), transform boundaries do not involve the creation or destruction of lithospheric material. Instead, they primarily accommodate horizontal displacement between plates without significantly changing their size or shape.
Transform boundaries are commonly observed along the mid-ocean ridges, where they connect segments of divergent boundaries, such as the famous San Andreas Fault in California, USA.

What is Labor?The procedure by which the placenta and fetus depart the uterus is called labor. Vaginal delivery (via the birth canal) and cesarean delivery (surgery) are the two possible methods of delivery.
In order for the fetus to pass through the birth canal, the cervix must first open (dilate) and thin (efface) during a series of ongoing, progressive contractions of the uterus called labor.
The Fair Labor Standards Act (FLSA) specifies requirements for minimum wage, overtime compensation, recordkeeping, and youth employment that are applicable to workers in the private sector and in federal, state, and municipal governments.
Typically, two weeks before or after the anticipated birth date, labor begins. Nobody, however, is entirely sure what starts labor.

a capacitor has a capacitance of 55.0 μf. if you want to store 155 j of electric energy in this capacitor, what potential difference do you need to apply to the plates?
Answers
Potential difference need to be apply to plates of capacitors is 5.63.
The capacitor is a two-terminal electrical device that stores energy in the form of electric charges.
C=55.0μf
E=155j
E=1/2cv^2
E=1/2*55.0*v^2=155
v=155*2/55.0=5.63v
potential difference is 5.63v.
The energy stored in a capacitor is nothing but the electric potential energy and is related to the voltage and charge on the capacitor. If the capacitance of a conductor is C, then it is initially uncharged and it acquires a potential difference V when connected to a battery.

What is shear strength?Shear strength in engineering refers to a material or component's resistance to a particular type of yield or structural failure when the material or component fails under shear. A force called a "shear load" tends to cause a material to fail slidingly along a plane parallel to the direction of the force. Scissors fail to shear a piece of paper when they are used to cut it.
For designing the dimensions and materials to be used for the manufacture or construction of a component, shear strength of a component is important in structural and mechanical engineering (e.g. beams, plates, or bolts). Reinforcing bar stirrups, also known as rebar, are used in reinforced concrete beams primarily to increase shear strength.

A fluid inlet to a mixing tank at a rate of 2.2 kg/min and NaCl added to the tank at a rate of 0.2 kg/min. The outlet fluid from the tank is at a rate of 2 kg/min. Initially the tank containing 8 kg of the fluid. Determine the concentration inside and outside the tank at time of 2 minutes.
Answers
At time t=2 min, the concentration inside the tank is 0.042 kg/kg and the concentration outside the tank is 0.476 kg/kg.
How did we get the values?To determine the concentration inside and outside the tank at 2 minutes, we need to use the mass balance equation:
mass in - mass out + mass generated = change in mass in the tank
At time t=0, the mass in the tank is 8 kg, and there is no mass generated. Thus, we have:
(2.2 + 0.2) kg/min - 2 kg/min + 0 kg/min = dM/dt
Simplifying, we get:
dM/dt = 0.4 kg/min
Integrating both sides, we get:
M(t) = M(0) + (dM/dt) * t
Plugging in the values, we get:
M(2) = 8 kg + (0.4 kg/min) * 2 min = 9.6 kg
Now, we can calculate the concentration inside and outside the tank:
Concentration inside the tank:
At time t=0, the concentration inside the tank is:
Cin(0) = 0 kg/kg (since there is no salt in the tank initially)
At time t=2 min, the amount of salt in the tank is:
Min(2) = 0.2 kg/min * 2 min = 0.4 kg
Thus, the concentration inside the tank is:
Cin(2) = Min(2) / M(2) = 0.4 kg / 9.6 kg = 0.042 kg/kg
Concentration outside the tank:
The rate of salt leaving the tank is 2 kg/min, and at time t=2 min, the total amount of salt leaving the tank is:
Mout(2) = 2 kg/min * 2 min = 4 kg
Thus, the amount of salt remaining in the tank is:
Mrem(2) = M(0) + Min(2) - Mout(2) = 8 kg + 0.4 kg - 4 kg = 4.4 kg
The total mass leaving the tank is 2 kg/min * 2 min = 4 kg. Thus, the concentration outside the tank is:
Cout(2) = Mout(2) / (M(0) + Min(2)) = 4 kg / 8.4 kg = 0.476 kg/kg
Therefore, at time t=2 min, the concentration inside the tank is 0.042 kg/kg and the concentration outside the tank is 0.476 kg/kg.

A horizontal poly crystalline solar panel module has to be investigated by natural cooling. For crystal silicon, the thermal coefficient approximately 0.0045/K is used. Investigate the effect of air velocity on the cooling performance of PV panels at 0-5 m/s air velocities, 25-40 ºC ambient temperatures, and 400-1000 W/ m2 solar radiation
Answers
Solution :
It is given that :
Thermal coefficient = 0.0045/K
Ambient temperature, \($T_a = 25 - 40^\circ$\)
air velocity, v = 0-5 m/s
Solar radiation, \($G= 400-100 \ W/m^2$\)
\($P=50 \ W$\)
Model calculations :
Cell temperature (\($T_c$\))
\($T_c = T_a + \left(\frac{0.25}{5.7+3.8 \ v_w}\right) G$\)
where \($ v_w - v_a = $\) wind speed / air speed
∴ \($T_c = 2 \pi + \left(\frac{0.25}{5.7+3.8 \times 1}\right) \times 400$\)
\($T_c = 35.526 ^\circ$\)
\($\Delta T = T_c -25$\)
= 35.526 - 25
= 10.526 K
Thermal coefficient = 0.0045 x 10.526
= 0.04737
Pv power = \($(1 -C_T) \times P \times \frac{G}{1000}$\)
