xz_007 [3.2K]

Answer:

a. Technician A

Explanation:

Technician A says that a MAF sensor is a high-authority sensor and is responsible for determining the fuel needs of the engine based on the measured amount of air entering the engine. Technician B says that a cold wire MAF sensor uses the electronics in the sensor itself to heat a wire 20°C below the temperature of the air entering the engine. Who is right

MAF wich stands for  mass airflow sensor determines the mass of air flowing into the engine's air intake system. ... , the wire cools When air flows past the wire, decreasing its resistance, thereby more current flows through the circuit. When the MAf goes bad, it can not sense the amount of air intake into the engine.

A 2 kg blob of sticky putty is thrown with a velocity of 5 m/s at a 1 kg doll. After impact, the putty sticks to the doll and co
kow [346]

Answer:3.33 m/s

Explanation:

Given

mass of Putty M=2 kg

the velocity of bob u=5 m/s

mass of doll m=1 kg

As there is no external force acting so linear momentum is conserved

Mu=(M+m)v

where v=common velocity of putty and doll after the impact

2\times 5=(2+1)v\\v=\dfrac{10}{3}\ m/s\approx3.33\ m/s

A lightbulb marked "75 W [at] 120 V" is screwed into a socket at one end of a long extension cord, in which each of the two cond
Vedmedyk [2.9K]

Answer:

Part c)

P = 73.8 Watt

Explanation:

Light bulb is marked as 75 W and 120 Volts

so it means that when we apply 120 volts across the bulb then it will consume the total power of 75 W

now when we connected the bulb with the help of conducting wires with some resistance across them then few of its voltage will fall across the wires

due to which the voltage across bulb is less than 120 Volts

So the power given by the bulb is less than 75 W

Part c)

Resistance of the bulb is given as

R = \frac{V^2}{P}

R = \frac{120^2}{75}

R = 192 ohm

now total resistance of the circuit

R_{net} = 192 + 0.8 + 0.8

now current in the circuit

i = \frac{120}{193.6}

i = 0.62 A

so actual power delivered to the bulb is given as

P = i^2 R

P = 0.62^2 \times 192

P = 73.8 Watt

Is this right? I need help, thank you
erastovalidia [21]

Velocity is correct, the symbol for acceleration is a. That is all I know.
