Given that
Number of poles= 8
I.E.C. 180L motor frame
From data book , for 8 poles motor at 50 Hz
Speed = 730 rpm
Power factor = 0.75
Efficiency at 100 % load= 89.3 %

The voltage difference in a graphing calculator is 6V and the resistance is 1200 what is the current through the batteries of the graphing calculator?
The current through the batteries of the graphing calculator is 0.005 A
How to calculate current through the batteries of the graphing calculator?The potential difference in charge between two sites in an electrical field is quantified as voltage, also known as electromotive force.
When charged electrons (current) are forced through a conducting loop by the pressure of an electrical circuit's power source, they can perform tasks like lighting a lamp. In a nutshell, voltage is measured in volts and equals pressure.
The derived unit for electric potential, voltage, and electromotive force is the volt (symbol: V). The Italian physicist Alessandro Volta (1745–1827), who created the voltaic pile, conceivably the first chemical battery, is honored by having his name attached to the volt.

during this period, which value best approximates the average value of the san lorenzo river's discharge in cubic feet per second (cfs)?
The total annual discharge of the San Lorenzo River, as recorded at the stream gage near Felton, was almost 400 cubic feet per second (cfs).
ExplanationJust before the Boardwalk, the San Lorenzo River flows through the center of Santa Cruz to the Monterey Bay. Along the river in the Boardwalk and downtown regions is the San Lorenzo Riverway Trail. San Lorenzo Park is located on the northern edge of city, close to the river. In the past, logs from the Santa Cruz Mountains were transported by the river. (To the headwaters of the San Lorenzo River from Felton through a flume.) Over time, the river has receded due to increased water demand. The water moves at a rate of roughly 10 cubic feet per second in the summer.

assume the skin friction drag on the airfoil is essentially that for a flat plate with the boundary layer being laminar and incompressible. what percentage of the total drag is due to skin friction?
Preliminary studies found that skin friction drag accounts for between 20 to 40% of overall drag.
Explain about the skin friction?Aerodynamic drag, which is a resistive force applied to an object moving in a fluid, includes skin friction drag.
The viscosity of a fluid as it passes across a surface is what creates skin friction. Its size is determined by the fluid's viscosity, the amount of wetted (or total) surface area in contact with it, and the degree of roughness of the surface.
Skin friction is important because it plays a role in the erosion of sediment particles from the water-bed boundary condition. Regarding the vertical mixing of the sediment over the water depth, form drag-related turbulence (separation-induced eddies, etc.) is significant.

wt steel shape is produced by cutting a wide flange beam lengthwise in half. group of answer choices true false
It is true that wt steel shape is produced by cutting a wide flange beam lengthwise in half.
A beam is a structural component that resists loads mostly applied laterally to its axis (an element designed to carry primarily axial load would be a strut or column). Its primary method of deflection is bending. Reaction forces are produced at the beam's support points as a result of the loads placed on it.
As a result of all the forces operating on the beam, internal stresses, strains, and deflections of the beam are caused by shear forces and bending moments within the beams. Beams differ from one another in terms of how they are supported, their profile (the form of their cross-section), equilibrium circumstances, length, and material.
Beams are typically used to describe structural elements in buildings or civil engineering when the beams are horizontal and support vertical loads.

According to technician b, in a fuel cell, electrons move from the anode to the cathode. is accurate in its assertion.
What is anode and cathode?At the anode, there is an oxidation reaction. This electrode would accumulate electrons as the oxidized species would lose electrons. As a result, the anode is negatively charged. In contrast to the cathode, the reduced species would get electrons in the reduction response. As a result, the electrode, or cathode, is positively charged because it is electron-free.Oxidation and reduction always take place at the anode and cathode, respectively. (Vowels go with other vowels; consonants go with other consonants.)Therefore, regardless of the type of cell you are dealing with, the chemicals that are oxidized send the electrons onto the external circuit at the anode, where they then move through the circuit from the anode to the cathode, where they are picked up by the chemicals that are being reduced.To learn more about anode and cathode refer to:

It is equivalent to the informal term "thickness" for liquids; syrup has a higher viscosity than water, for instance.The internal frictional force between neighbouring fluid layers that are moving relative to one another is measured by viscosity. A viscous fluid, for instance, flows more swiftly near a tube's axis than it does near its walls when the fluid is driven through the tube.The state of a fluid, including its temperature, pressure, and rate of deformation, affects its viscosity. In some circumstances, the dependence on some of these traits is minimal.Various viscometer and rheometer types are used to measure viscosity.
