Since Tech B says that some airflow sensors use a hot wire to determine mass airflow he is the only one that is correct.
<h3>How does a mass
airflow sensor work?</h3>
An MAF is one that consist of two sensing wires. One is known to be heated by the use of electrical current, while the other is not.
There are different kinds of wires for different kinds of purposes.
Tech A saying that mass airflow sensors determine mass airflow based on engine speed and manifold pressure is incorrect because that is not the role of the mass airflow sensors.
l
As air flows across the heated wire, it cools down. Hence, Since Tech B says that some airflow sensors use a hot wire to determine mass airflow he is the only one that is correct.

Explanation:
Strengthening is the method to improve the strength of material because different type of material property requires for different requirement .Some times requires more ductility,some time requires more strength.
When impurities are mixed with the pure metal then the strength of metal will increases and this is called the strengthening of metal.
The methods of strengthening are as follows
1.Solid solution strengthening and alloying
2.Work hardening
3.Transformation hardening
4.Grain boundary strengthening
5.Precipitation hardening
The acceleration at points A, B and C are respectively; 960 mm²/s, 1600 mm²/s and 600 mm²/s
<h3>What is the acceleration?</h3>
The drum rolls without sliding and as such its' instantaneous center will lie at B. Thus;
V_d = V_c = 160 mm/s
Also, a_d = a_c = 600 mm²/s
Now, formula for velocity at A is;
V_a = r_ab * ω
where ω = 160/(100 - 60)
ω = 4 rad/s
V_a = 60 * 4
V_a = 240 mm/s
Acceleration at A = V_a²/r_ab
Acceleration at A = 240²/60 = 960 mm²/s
Now, V_b = 100 * 4 = 400 mm/s
Acceleration at B = 400²/100 = 1600 mm²/s
