A 10 Ω resistor is connected to a 120-V ac power supply. What is the peak current through the resistor?

11111nata11111 [884]

Answer:

Peak current = 16.9 A

Explanation:

Given that

RMS voltage = 120 Volts

$V_{rms} = 120 V$

AC is connected across resistance

$R = 10 ohm$

now by ohm's law

$V = i R$

$120 = i (10)$

$i_{rms} = \frac{120}{10} = 12 A$

now peak value of current will be given as

$i_{peak} = \sqrt{2} i_{rms}$

$i_{peak} = \sqrt2 (12) = 16.9 A$

A jet aircraft is traveling at 262 m/s in horizontal flight. The engine takes in air at a rate of 85.9 kg/s and burns fuel at a

Fittoniya [83]

Answer:

$F_T=60132.52N$

$P=15814852.76W$

Explanation:

From the question we are told that

Velocity of aircraft $V=263m/s$

Engine air intake rate $\triangle M_a=85.9kg/s$

Fuel burn rate $\triangle M_f =3.92kg/s$

Velocity of exhaust gas $V_e =921m/s$

Generally the Mass change rate of Rocket is mathematically given by

$\triangle M = \triangle M_a+\triangle M_f$

$\triangle M= 85.9+3.92$

$\triangle M=89.82kg/s$

Generally the Trust of the rocket is given mathematically by

$F_T=(\triangle M *V_e)-(dM_a/dt)*(V)$

$F_T=(89.82 *921)-(85.9)*(263)$

$F_T=60132.52N$

Generally the Rocket's delivered power is mathematically given by

Delivered power P

$P=V*F_T$

$P=263*60132.52N$

$P=15814852.76W.$

Explain why gases are good insulators?

Zepler [3.9K]

Answer:Gases do not conduct heat as well as liquids and are therefore good insulators. Gases consist of widely spread out particles, and it takes contact to conduct heat. ... They are insulators if they are not ionized and there are no free charged particles there that can carry electric current.
