<u>Answer:</u> The correct answer is Option 1.
<u>Explanation:</u>
There are three subatomic particles in an atom. They are: electrons, protons and neutrons.
- <u>Protons:</u> They carry positive charge and are found in nucleus.
- <u>Electrons:</u> They carry negative charge and are found around the nucleus.
- <u>Neutrons:</u> They dos not carry any charge and are found in nucleus.
Mass of protons and neutrons are almost same and they both contribute to the mass of an atom.
Mass of electrons is very negligible as compared to protons and neutrons.
Masses of the subatomic particles:
Mass of protons = 1.007276 u
Mass of neutrons = 1.008664 u
Mass of electrons = 0.00054858 u
Hence, the correct answer is Option 1.
The answer would possible be letter a
Wet chemical system components typically are a storage tank or tanks, piping, nozzles, and an actuating mechanism.
<h3>
Which parts make up an actuation mechanism?</h3>
The typical components of an actuation mechanism include a motor, transmission, control units, feedback, signaling, interlocking, and shutdown units. An electrical, hydraulic, or pneumatic drive is used to move a valve, shutter, or gate, which acts as an actuator to regulate the flow of fluids or gases.
<h3>
What is the operation of the operator-dependent actuating mechanism?</h3>
When an automatic clutch is engaged, the control system 2 replaces the target-value signals coming over feeders 1 with the operator force signal if the operator uses the operator-dependent actuating mechanism.
