Answer:
1st Harmonic:
3rd Harmonic:
5th Harmonic:
7th Harmonic:
Explanation:
The general form to represent a complex sinusoidal waveform is given by
Where A is the amplitude in volts of the sinusoidal waveform
Where f is the frequency in cycles per second (Hz) of the sinusoidal waveform
Where 
is the phase angle in radians of the sinusoidal waveform.
1st Harmonic:
We have A = 50, f = 1000 and φ = 0
3rd Harmonic:
We have A = 9, f = 3000 and φ = 0
5th Harmonic:
We have A = 6, f = 5000 and φ = 0
7th Harmonic:
We have A = 2, f = 7000 and φ = 0
Note: The even-numbered harmonics have 0 amplitude that is why they are not shown here.
The principles referred to in the question are called biomechanical principles. Some of them are:
- Principles of Force; and
- The principle of impulse direction.
<h3>What principle is most relevant to jumping?</h3>
The principle that is most relevant to jumping is called Angular Momentum.
<h3>
What is Angular Momentum?</h3>
Simply defined, this refers to the velocity of the rotation of a body around an axis or a fixed point.
Other principles of biomechanics are the principles of:
- linked segments.
- impulse-causing momentum.
- the stretch-shorten cycle.
- summing joint forces.
- continuity of joint forces.

Answer:
Technician B only is correct
Explanation:
Voltage drop testing is a method used to find the amount of electrical resistance available in an high amperage circuit that involves connecting the leads of the meter in parallel to the circuits being tested such that disassembly is not required
In voltage drop test, the red voltmeter lead and black voltmeter lead are placed at two points on the same side of the circuit connection such that the leads are in between two positive connection or two negative connection (rather than connecting the red to the positive and the black to the negative sides of the circuit) and digital voltmeter is used for the voltage drop measurement across the lead while the connection is under load.
Therefore, Technician B only is correct
