Answer:
Conditions that result in the emission of electrons from a conductor:
Heating the conductor to a suitable temperature
Exposing the conductor to a strong light
Subjecting the conductor to a very high applied voltage
Subjecting the conductor to high-speed electrons from another source
Both diodes and triodes influence current flow and contain electrodes. Diodes involve only two active pieces; triodes contain three electrodes within a tube. Current can flow through a diode in only one direction. Diodes tend to act as rectifiers. In a triode, the third electrode is a grid located between the cathode and the anode. A small difference of potential between the grid and the cathode controls the number of electrons that reach the anode. Adjusting the charge on the grid affects the number of electrons that can reach the anode. Triodes tend to act as amplifiers.

Power = Work / Time
If W = 50 J and T = 5s
P = W/T = 50J/5s = 10 Watts
The answer would be false
The photography that shows a person using a type of wave technology, allows people to see very small objects clearly. D as it is a microscope
<h3>Why are wave technologies important?</h3>
Wave technologies are important because;
- They create waves that are more perfect than humans can provide by themselves.
- Certain inventions use waves to enhance human senses like hearing, sight and touch.
Thus, the photography that shows a person using a type of wave technology, allows people to see very small objects clearly. D as it is a microscope.
