Answer:
We will see a waveform displayed on the screen and it will be PWM(pulse width modulation) of sinusoidal wave,this wave should have a frequency of 14KHz and it will form a vibration spectrum.
Answer:
Both are incorrect.
Explanation:
PCV valve opening is dependent on amount of manifold vacuum value. The opening cannot decrease due to part throttle operation. The PCV system is a tampered valve whose opening depend upon intake manifold vacuum. PCV valve is supported by a spring and is initially in a closed position.

The Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s. See the computation below.
<h3>What is travel speed?</h3>
The travel speed of the welding flame or gun across the workpiece is simply measured in millimeters per minute.
Travel speed, along with voltage and amperage, is one of three factors in arc welding that affect the amount of heat input.
<h3>What is the calculation that justifies the above answer is?</h3>
We are given the following:
Melting temperature = 1650 K
k = (3.33 * 10⁻⁶) * (1,650)²
k = 9.066 J/mm^3
The formula for velocity here is given as:
V = f1 * f2 * Rh / (k*A)
V = 0.9 * 0.6 * 3000 / (9.066*25)
V = 7.147 mm/s
Hence, the Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s.
