Answer:

R = 0

Explanation:

The output R is the result of the function ...

R = (P+Q)·Q'

This simplifies to ...

R = PQ' + 0

R = PQ'

The result R will be the AND of P=0 and Q'=(1-1)=0. Any AND function with a 0 input will have a 0 output.

R = 0

What is arduino and for what it is used

Eva8 [605]

Answer:

Arduino es una plataforma electrónica de código abierto basada en hardware y software fácil de usar. Las placas Arduino pueden leer entradas (luz en un sensor, un dedo en un botón o un mensaje de Twitter) y convertirlo en una salida: activar un motor, encender un LED, publicar algo en línea.

Explanation:

utilizado para la construcción de proyectos electrónicos. Consiste en una placa de circuito programable física y un software, o IDE (Integrated Development Environment) que se ejecuta en su computadora, donde puede escribir y cargar el código de la computadora en la placa física.

Air is flowing steadily through a cooling section where it is cooled from 30 °C to 15 °C at a rate of 0.25 kg/s.

Lady bird [3.3K]

Answer:

$C_{day} = 2.261\,USD$

Explanation:

The heat transfer rate rejected to the refrigeration system is:

$\dot Q_{L} = (0.25\,\frac{kg}{s} )\cdot (1.005\,\frac{kJ}{kg\cdot ^{\textdegree}C} )\cdot (30\,^{\textdegree}C-15\,^{\textdegree}C)$

$\dot Q_{L} = 3.768\,kW$

The electric power needed to make refrigeration possible is:

$\dot W = \frac{\dot Q_{L}}{COP_{R}}$

$\dot W = \frac{3.768\,kW}{2.8}$

$\dot W = 1.346\,kW$

The daily energy consumption is:

$\Delta E_{day} = (1.346\,kW)\cdot (86400\,s)$

$\Delta E_{day} = 116294.4\,kJ$

$\Delta E_{day} = 32.304\,kWh$

The cost of electricity consumed by the air-conditioner per day is:

$C_{day} = c\cdot \Delta E_{day}$

$C_{day} = (0.07\,\frac{USD}{kWh} )\cdot (32.304\,kWh)$

$C_{day} = 2.261\,USD$

Keith_Richards [23]

The IRS and the U.S Department of the treasury declared that social security recipients are not required to file a simple tax return to receive stimulus payments under the CARES Act.

Explanation:

Due to the impact of corona virus problem, the CARES Act calls for stimulus payment to be sent to Americans based on their gross income.

The Social security recipients are not required to file a tax return and do not take action and they will receive the payments directly to their bank accounts.

The Automatic payments will begin by next week. The eligible taxpayers who filed tax returns for 2019 or 2018 and chose direct deposit for their refund will automatically receive a stimulus payment of $1,200 for individuals or $2,400 for married couples and $500 for each qualifying child.

For a copper-silver alloy of composition 25 wt% Ag-75 wt% Cu and at 775C (1425F) do the following: (a) Determine the mass frac

allochka39001 [22]

Answer:

mass fraction of α = 0.796

mass fraction of β = 0.204

mass fraction of primary α (Wα) = 0.734

mass fraction of eutectic micro-constituents (We) = 0.266

α in eutectic mixture = 0.062

Explanation:

Assumptions:

(i) the system is in thermal equilibrium with its surroundings

(ii) There are no impurities or other alloying elements present

(a) Determine the mass fractions of α and β phases

From the Cu - Ag phase diagram, Cα = 8.0 wt% Ag, Cβ = 91.2 wt% Ag, and C0 = 25 wt% Ag .Using the lever-rule:

Total mass fraction of α = (Cβ - C0) / (Cβ - Cα) = (91.2 - 25) / (91.2 - 8) = 0.796

Total mass fraction of β = (C0 - Cα) / (Cβ - Cα) = (25 - 8) / (91.2 - 8) = 0.204

(b) Determine the mass fractions of primary α and eutectic microconstituents

Ceutetic = 71.9 wt.%Ag

mass fraction of primary α (Wα) = (Ceutetic - C0) / (Ceutetic - Cα) = (71.9 - 25) / (71.9 - 8) = 0.734

mass fraction of eutectic micro-constituents (We) = (C0 - Cα) / (Ceutetic - Cα) = (25 - 8) / (71.9 - 8) = 0.266

From the eutetic reaction, L ↔ α + β

Total α = Primary α + α in eutectic mixture

Therefore: α in eutectic mixture = Total α - Primary α = 0.796 - 0.734 = 0.062
