At a certain elevation, the pilot of a balloon has a mass of 120 lb and a weight of 119 lbf. What is the local acceleration of g

ravity, in ft/s2, at that elevation? If the balloon drifts to another elevation where g = 32.05 ft/s2, what is her weight, in lbf, and mass, in lb?

Response:

1) g=31.87ft/s^2

2)m=120

W=119.64lbf

Clarification:

initial segment

the weight of an object with a specified mass is determined using the equation

W=mg

we need to convert 120lb into slug

m=120lbx1slug/32.147lb=3.733slug

calculating for g

g=W/m

g=119/3.733=31.87ft/s^2

subsequent segment

the mass remains unchanged

m=120lb=3.733slug

Weight

W=3.733slug*32.05ft/s^2=119.64lbf

Answer:

An attachment follows below

Explanation:

1) The formula used for the damping coefficient in a series RLC circuit.

If \xi = 0, it is possible to set c = 0 but an inductor will still possess some capacitance.

2) The behaviors of critically damped and underdamped systems are illustrated along with comments on their temporal responses.

4) While several answers might suffice, the four I’ve highlighted are the crucial parameters necessary about an unknown op-amp before utilizing it in a circuit.

Hope this addresses all your inquiries.

Suppose we include the lead resistance in the calculation of temperature for a class A RTD. If R3 = 1000 ohms, Ra = 18 ohms, V0
alex41 [359]

Respuesta:

La temperatura máxima que se puede medir (en °C) es 14170.27°C

Explicación:

Los RTDs son termómetros compuestos de metales cuya resistencia aumenta con la temperatura.

Para un RTD de Clase A, l, Alpha = 0.00385.

La fórmula para el RTD es

Rt = Ro ( 1 + alpha x t)

Donde

Rt es la resistencia a la temperatura t°C,

Ro es la resistencia a 0°C

Alpha es un coeficiente de temperatura constante para un RTD de clase A.

Aquí, Rt = 1000ohms,

Ro se considera como Ra = 18Ohms

Por lo tanto,

1000 = 18 ( 1 + 0.00385t)

Dividiendo ambos lados por 18

1 + 0.00385t = 1000/18

0.00385t = 55.55 - 1

0.00385t = 54.55

t = 54.55/0.00385

t = 14170.27°C

iogann1982 [368]

Answer:

Provided information

 an electronic system dissipating = 90 W

diameter = 15 cm

The duct has components cooled by forced air entering at 32°C with a flow rate of 0.65 m3 /min

85% of the generated heat is transferred to the air in the duct, and 15% is lost through the duct's outer surfaces.

See the attached images for the solution.

Explanation:

Consult the attached pictures for a thorough breakdown of the explanation.
