Answer:
Explanation:
t1 = 1000 F = 1460 R
t0 = 80 F = 540 R
T2 = 3600 R
The working substance has an available energy in reference to the 80F source of:
B1 = Q1 * (1 - T0 / T1)
B1 = 100 * (1 - 540 / 1460) = 63 BTU
The available energy of the heat from the heat wource at 3600 R is
B2 = Q1 * (1 - T0 / T2)
B2 = 100 * (1 - 540 / 3600) = 85 BTU
The reduction of available energy between the source and the 1460 R temperature is:
B3 = B2 - B1 = 85 - 63 = 22 BTU
Answer:
Batteries work by storing negative photons on one side then transfering them to the positive side and everything thats inbetween
Explanation:
Answer:
B) Attenuation
Explanation:
Attenuation can be regarded as the loss of signal strength which could be as a result of both external and internal factors. This loss of signal strength could occur in networking cables as well as other connections. Attenuation is a loss in energy, because as signal travels, its strength decreases as a a result of distance it covers, this loss of energy is due to the signal trying to overcome the resistance at the medium. One of the main the causes of attenuation is When there is Extra noise on available networks, networks such as electrical current as well as radio waves. It should be noted that attenuation is Signal loss which is the reduction of a signal that occurs in a medium as a function of the physical length of the channel.
Singnal attenuation can taken care of by using lower loss materials with high cost, instead of making of PCB routing length reduction. Amplifiers can also be engaged in amplifying attenuated signal to get back the original signal, this will compensate the loss.
Attenuation can be measured in decibels(dB), this gives the measurement of relative strengths of one signal at two different point or measurement of two signals.
Answer:
The upper diode conduces in the odd half cycles. The lower diode conduces in the even half cycles.
Explanation:
The peak voltage after the 6 to 1 step down is . Then, the peak voltage of the rectified output is V_{d}[/tex] and according to the statement, the diodes can be modeled to be . Then, the peak voltage in the load is .
The upper diode conduces in the odd half cycles. The lower diode conduces in the even half cycles.
The average output voltage is calculated as:
The average current in the load is calculated as:
The rigging device which are used to move loads without the use of slings, but grip the load by biting down and using jaw tension to secure the load, is lifting clamps.
<h3>What are the rigging devices?</h3>
The rigging devices are used to lift the objects and items when the safety is required. This device is used in the industries.
Types of rigging devices
- Rigging hooks-These rigging device is used when the heavy load need to be lift.
- Lifting clamps-Lifting clamp are used to lift the device with jaw tension to secure the load. In this, there is no use of slings.
- Pulley and blocks-In the load is lifts with the help of block and pulley arrangement. This is a widely used rigging device.
Thus, the rigging device which are used to move loads without the use of slings, but grip the load by biting down and using jaw tension to secure the load, is lifting clamps.
