Answer:
Higher-level human resources related to engineering are those who:
- Assist other engineers with solving complex problems.
- Work with management to keep the project on track.
- Mentor younger engineers
Medium Level engineers will normally comprise the following:
- They are responsible for developing engineering plans and performing calculations with respect to the same.
- Project workflow management
- Engineering Support facilitation
- Project Reporting
- Coordination of Team Members

It's either staying there or is going at the same pace
This is a Doppler effect. Generally, if you move to a frequency source, you would detect an increase in frequency and when you move away from a source you would detect a decrease.
For this question, before you pass them, you are actually approaching them, so you would hear a higher frequency than the constant 300 Hz they are playing at.
Using the condensed formula:
f ' = ((v <u>+</u> vd)/(v <u>+</u> vs)) * f
Where: vd = Velocity of the detector.
vs = Velocity of the frequency source.
v = Velocity of sound in air.
f ' = Apparent frequency.
f = Frequency of source.
v = 343 m/s, vd = detector = 27.8 m/s, vs = velocity of the source =0. (the flautists are not moving).
f = 300 Hz.
There would be an overall increase in frequency, so we maintain a plus at the numerator and a minus at the denominator.
f ' = ((v + vd)/(v - vs)) * f
f ' = ((343+ 27.8)/(343 - 0)) * 300
= (370.8/343)* 300 = 324.3
Therefore frequency before passing them = 324.3 Hz.
Cheers.
Answer:
The cross-sectional area is
Explanation:
From the question we are told that
The dimension of the cell is 6.9 × 10-4 cm by 1.1 × 10-3 cm =
Generally the cross-sectional area is mathematically represented as
=>
<h2>
Answer</h2>
the anser is (C) as <u>240 Watt</u>
<h2>
Explanation</h2>
As we know that
As given in question
Force = 150 N
Distance = 4m
Then work is
So the answer is <u>240 watt</u>
