The correct answer is when retentive power is restored the accumulated count will be 300.

PLC counters are normally retentive; that is, whatever count was contained in the counter at the time of a proces- sor shutdown will be restored to the counter on power-up. The counter may be reset, however, if the reset condition is activated at the time of power restoration.A counter instruction is an input instruction. A counter's input signal can come from an external device such as a sensor. Up and down counters may be programmed together to count up and down. Counters can count past their preset values.

No underwater luminaires shall be installed in a permanently-installed swimming pool that operates on supply circuits over 150 volts between conductors.

A circuit in electronics is a closed path that enables the movement of electricity from one point to another. A gap or break in the circuit does not obstruct the flow of current, even though it may contain a variety of electrical components like transistors, resistors, and capacitors.

A basic circuit is something like a flashlight. Because the circuit is not closed when the switch is off, no electricity will flow from the batteries to the flashlight's bulb. A piece of metal inside the flashlight physically closes the circuit gap when you turn the switch to the on position. The bulb then illuminates as a result of the batteries' electrical flow.

Load cells are connected to external resistors in order to form a Wheatstone bridge circuit.


The Wheatstone bridge configuration is commonly used in load cell designs to convert mechanical force or weight measurements into electrical signals that can be accurately measured and interpreted Load cells typically consist of strain gauges, which are sensors that change their resistance in response to applied mechanical stress or strain. These strain gauges are connected to form a Wheatstone bridge circuit, along with precision resistors.By applying a known excitation voltage to the Wheatstone bridge circuit, any change in resistance due to the applied force on the load cell causes an imbalance in the bridge. This imbalance produces a small differential voltage output, which is directly proportional to the applied force or weight.The external resistors in the Wheatstone bridge circuit help to balance and calibrate the load cell. They ensure that the bridge is properly compensated and provides accurate and precise measurements. By adjusting the values of these resistors, the sensitivity and output range of the load cell can be fine-tuned to match the desired application requirements.

From electrical energy to radiation

Explanation:

A light bulb converts electrical energy to light, which is nothing more than radiation. Don't regard radiation as a bad thing, this light is non-iodizing radiation, which does not have the possibility to alter our DNA, and thus it's safe.

The simplest example can be found in old lights (obsolete now because they are vastly inefficient). This lights were just resistors which turned electrical energy into heat. A very hot material reflects light in the form of radiation, as described above.

Answer:

a) 208.33 A

b) 1.152 Ω

c) 0.03456 Ω

d)  6943.64 A

Explanation:

Transformer ratings :

Base power ( Sb ) = 50 KVA ,  

Transformer voltage = 2400 / 240 V ,  

Impedance ( Zp.u ) = 3.0 % = 0.03

phase = single ( 1 ) phase

Base Voltage on low side ( Vb ) = 240 V

a) Calculate the base current ( Ib )

Ib = Sb / Vb = ( 50 * 10^3 ) / 240

                    = 208.33 A

b) calculate base impedance ( Zb )

Zb = Vb^2 / Sb = ( 240 )^2 / 50000

                        = 1.152 Ω

c) Calculate the actual impedance ( Zact )

Zact = Zp.u * Zbase

       = 0.03 * 1.152 = 0.03456 Ω

d) Calculate the short circuit current ( Isc )

Isc = Vp.u / Zp.u      

     = 1 / 0.03 = 33.33 p.u

therefore Isc = 33.33 * Ib

                     = 33.33 * 208.33 = 6943.64 A

Answer:

Explanation:

In this context, we are dealing with the cooling of hot air as it flows through tubes exposed to atmospheric air. Based on this, we can make the following statements:

a. Heat transfer coefficient inside the tube will be higher - This statement is false. As the hot air flows through the tube and comes into contact with the cooler atmospheric air outside the tube, heat transfer occurs between the two fluids. In this process, the temperature difference between the two fluids drives the heat transfer. Therefore, the heat transfer coefficient inside the tube will be lower because the hot air will have a higher temperature than the atmospheric air, and the temperature difference will be smaller.

b. Heat transfer coefficient inside the tube will be lower - This statement is true, as explained in the previous statement.

c. Fins should be attached to the outside of the tube - This statement is true. Fins are used to increase the surface area of the tube, which in turn increases the rate of heat transfer between the hot air inside the tube and the atmospheric air outside. Attaching fins to the outside of the tube will increase the surface area exposed to the atmospheric air, facilitating faster cooling of the hot air.

d. Fins should be attached to the inside of the tube - This statement is false. Attaching fins to the inside of the tube will actually reduce the effective cross-sectional area of the tube, restricting the flow of air and hindering the heat transfer process. Therefore, fins should be attached to the outside of the tube to maximize the surface area and facilitate efficient heat transfer.

The first legal procedural step the Navy must take to obtain the desired change to airspace designation is to submit a proposal to the FAA.

What is airspace designation?

Airspace designation is the division of airspace into different categories. The FAA (Federal Aviation Administration) is responsible for categorizing airspace based on factors such as altitude, aircraft speed, and airspace usage. There are different categories of airspace, each with its own set of rules and restrictions. The purpose of airspace designation is to ensure the safe and efficient use of airspace for all aircraft, including military and civilian aircraft.

The United States Navy (USN) may require a change to airspace designation to support its operations.

he navy must follow a legal procedure to request and obtain the desired change. The first step in this process is to submit a proposal to the FAA. This proposal should provide a clear explanation of why the Navy requires a change to the airspace designation. The proposal should include details such as the location of the airspace, the type of aircraft operations that will be conducted, and any safety concerns that the Navy has.

Once the proposal has been submitted, the FAA will review it and determine whether the requested change is necessary and appropriate. If the FAA approves the proposal, the Navy can proceed with the necessary steps to implement the change.
