<h3><u>The fulcrum should be placed 0.44 from the 12 N weight or 0.56 m from the 8 N weight.</u></h3>

Explanation:

<h2>Given:</h2>

w_1 = 8 N

w_2 = 10 N

Since the meter stick has a length of 1 m, and d_1 \:+\:d_2\:=\:1\:m

Let d_1 = x

Let d_2 = 1 - x

<h2>Question:</h2>

Where should the fulcrum be placed to have the meterstick balanced?

<h2>Equation:</h2>

For the system to be balanced, the product of the weight and distance of the objects on opposite sides should be equal. This is is shown by the equation:

w_1 d_1 = w_2 d_2

where: w - weight

d - distance from the fulcrum

<h2>Solution:</h2>

Substituting the value of w_1, \:w_2, \:d_1  \: and\: d_2 in the formula,

(8 N)(x) = (10 N)(1 m - x)

x(8 N) = (10 N)m - x(10 N)

x(8 N) + x(10 N) = (10 N) m

x(18 N) = 10 N

x = \frac{(10 \:N)m}{18 \:N}

x = 0.56

<h3>Solve for d_1 </h3>

d_1 = x

d_1 = 0.56 m

<h3>Solve for d_2 </h3>

d_2 = 1 m - x

d_2 = 1 m - 0.56 m

d_2 = 0.44 m

<h2>Final Answer:</h2><h3><u>The fulcrum should be placed 0.44 from the 12 N weight or 0.56 m from the 8 N weight.</u></h3>

An air-conditioning system operating on the reversed Carnot cycle is required to transfer heat from a house at a rate of 755 kJ/
Lyrx [107]

Answer:

There is 0.466 KW required to operate this air-conditioning system

Explanation:

<u>Step 1:</u> Data given

Heat transfer rate of the house = Ql = 755 kJ/min

House temperature = Th = 24°C = 24 +273 = 297 Kelvin

Outdoor temperature = To = 35 °C = 35 + 273 = 308 Kelvin

<u>Step 2: </u> Calculate the coefficient of performance o reversed carnot air-conditioner working between the specified temperature limits.

COPr,c = 1 / ((To/Th) - 1)

COPr,c = 1 /(( 308/297) - 1)

COPr,c = 1/ 0.037

COPr,c = 27

<u>Step 3:</u> The power input cna be given as followed:

Wnet,in = Ql / COPr,max

Wnet, in = 755  / 27

Wnet,in = 27.963 kJ/min

Win = 27.963 * 1 KW/60kJ/min  = 0.466 KW

There is 0.466 KW required to operate this air-conditioning system

Consider a 6-bit cyclic redundancy check (CRC) generator, G = 100101, and suppose that D = 1000100100. 1. What is the value of R
dmitriy555 [2]

Answer:

The value of R is 10101

Explanation:

As per the given data

D = 1000100100

G = 100101

Redundant bit = 6-bits - 1-bit = 5-bits

No add fice zero to D

D = 100010010000000

Now calculate R as follow

R = D / G

R = 100010010000000 / 100101

R = 10101
