Limpies are best used for removing shrub structural branch defects.

Limpies are specialized pruning tools commonly used in horticulture and arboriculture. They are specifically designed for the precise and careful removal of shrub structural branch defects. These defects can include broken, dead, diseased, or crossing branches that affect the overall health and aesthetics of the shrub. Limpies are equipped with sharp blades and a scissor-like action, allowing for clean and accurate cuts to be made close to the main stem or branch collar. This helps promote proper healing and reduces the risk of disease or insect infestation. While limpies can be used for general pruning tasks, they excel in addressing structural branch defects and maintaining the overall health and integrity of shrubs.

The first code declares a variable called num and gives it an initial value of 0. It then enters a while loop that lauches a message box (using window.alert) to print the message "Keep going" as long as num remains less than 5.

If nothing is done within the loop to increment num towards the value 5, the loop will go on endlessly notifying the user to "Keep going".

The time required for this system to come to rest is equal to 9.87 seconds.

Given the following data:

In order to calculate the time required for this system to come to rest, we would have to determine the moment of inertia for gears A and C.

Mathematically, the moment of inertia for a gear can be calculated by using this formula:

I = mr²

Where:

For gear A, we have:

I = mr²

I = 0.675 × 0.04²

I = 0.675 × 0.0016

I = 1.08 × 10⁻³ kg·m².

For gear C, we have:

I = mr²

I = 3.6 × 0.1²

I = 3.6 × 0.01

I = 0.036 kg·m².

Next, we would convert the initial angular velocity of gear C in revolution per minutes (rpm) to radian per seconds (rad/s) as follows:

ωc₁ = 2000 × 2π/60

ωc₁ = 4000π/60

ωc₁ = 209.44 rad/s.

Also, the initial angular velocity of gears A and B is given by:

ωA₁ = ωB₁ = rc/rA × (ωc₁)

ωA₁ = ωB₁ = 0.15/0.06 × (209.44)

ωA₁ = ωB₁ = 2.5 × (209.44)

ωA₁ = ωB₁ = 523.60 rad/s.

Taking the moment about A, we have:

I_A·ωA₁ + rA∫F_{AC}dt - M(f)_A·t = 0

Substituting the given parameters into the formula, we have;

(1.08 × 10⁻³)·(523.60) + 0.06∫F_{AC}dt - 0.15t = 0

0.15t - 0.06∫F_{AC}dt = 0.56549    ......equation 1.

Similarly, the moment about B is given by:

0.15t - 0.06∫F_{BC}dt = 0.56549    ......equation 2.

Note: Let x = ∫F_{BC}dt + ∫F_{AC}dt

Adding eqn. 1 & eqn. 2, we have:

0.3t - 0.06x = (0.56549) × 2

0.3t - 0.06x = 1.13098      ......equation 3.

Taking the moment about A, we have:

Ic·ωc₁ - rC∫F_{AC}dt - rC∫F_{BC}dt - Mc(f)_A·t = 0

0.036(209.44) - 0.3t - 0.15(∫F_{BC}dt + ∫F_{AC}dt) = 0

0.3t + 0.15x = 7.5398      ......equation 4.

(a) 5.432 g : 4 significant figures

(b) 40.319 g: 5 significant figures

(c) 146 cm: 3 significant figures

The significant figures are the digits that are certain plus one digit that is uncertain.

In a measure, all the non-zero digits and the zeros between two non-zero digits are significant (take this as the first rule).

That rule apply for the items (a) through (d).

With that rule, then, you get the answer for the first four questions.

(a) 5.432 g: all the digits are different from zero, so all 4 are significant.

(b) 40.319 g: all digits are non-zero, so all 5 are significant.

(c) 146 cm: all digits are non-zero, so all 3 are significant.

(d) 3.285 cm: all digits are non-zero, so all 4 are significant.

In a decimal number, the leading zeros before the first non-zero digit are not significant (second rule)

(e) 0.189 s: 3 significant figures

So, with the second rule, you have that the 0 before the perios is not significant, and with the first rule you get that the 3 decimal (which are non-zeros) are significant.

(f) 429.3 mm: 4 significant figures

For this number use the first rule: all the digits are non-zero, so the 4 digits are significant.

(g) 2873.0: 5 significant figures

Now our third rule: all the trailing zeros to the right of the decimal point are significant.

That means that the digit 0 after the decimal point is significant. Since the other 4 digits are non-zero, the first rule may you conclude that they are also significant. So, the 5 digits are significant.

(h) 990 ml: 2 significant figures

New (fourth rule): the zeros that are only place holders are not significant.

So, the last 0 in 990 is not significant, and only the two non-zero digits (99) are significant figures.

(i) 0.0000246 g: 3 significant figures

With this number use the second rule (the leading zeros before the first non-zero digit are not significant), so the three non-zero digits are the signiticant figures.

(j) 1.04 × 10¹² g: 3 significant figures

This number is written in scientific notation. Only the digits of the mantissa (the digits before the power of 10) are taken into account to determine the number of significant figures.

So, use the previous rules with the number 1.04: first rule, all the non-zero digits and the zeros between two non-zero digits are significant. So the 3 digits in 1.04 are significant.

(k) 5.59 x 10⁻⁷ m: 3 significant figures

This number is also written in scientific notation, so only use the mantissa.

As per the first rule, all non-zero digits are signficant, so this number has 3 significant figures.

(l) 0.0000242 mg: 3 significant figures

The four zeros before 242 are just place holders, so as per the fourth rule, they are not signficant, and this number has 3 significant numbers (the three non-zero digits).

Resistance of copper = 1.54 * 10^18 Ohms

Explanation:

Given the following data;

Length of copper, L = 3 kilometers to meters = 3 * 1000 = 3000 m

Resistivity, P = 1.7 * 10^8 Ωm

Diameter = 0.65 millimeters to meters = 0.65/1000 = 0.00065 m

\( Radius, r = \frac {diameter}{2} \)

\( Radius = \frac {0.00065}{2} \)

Radius = 0.000325 m

To find the resistance;

Mathematically, resistance is given by the formula;

\( Resistance = P \frac {L}{A} \)

Where;

First of all, we would find the cross-sectional area of copper.

Area of circle = πr²

Area  = 3.142 * (0.000325)²

Area = 3.142 * 1.05625 × 10^-7

Area = 3.32 × 10^-7 m²

Now, to find the resistance of copper;

\( Resistance = 1.7 * 10^{8} \frac {3000}{3.32 * 10^{-7}} \)

\( Resistance = 1.7 * 10^{8} * 903614.46 \)

Given:-

Condenser exit parameters:

 P1 = 50 KPa  , saturated liquid

Boiler exit / Turbine exit parameters:

P3 = 2 MPa

T3 = 1100°C

Solution:-

- Adiabatic and reversible processes for pump and turbine are to be applied

- Assume changes in elevation heads within the turbomachinery to be negligible.

- Assume steady state conditions for fluid flow and the use of property tables will be employed.

Isentropic compression of water in pump:

 Pump inlet conditions :                       Pump exit to Boiler pressure:

  P1 = 50 KPa, sat liquid                         P2 = P3 = 2 MPa

  h1 = 340.54 KJ/kg                               s2 = s1 = 1.0912 KJ/kg.K

  s1 =  1.0912 KJ/kg.K                              h2 = 908.47 KJ/kg

- Apply energy balance for the pump and determine the work input ( Win ) required by the pump:

                     Win = h2 - h1

                     Win = 908.47 - 340.54

                     Win = 567.93 KJ/kg

Isentropic expansion of steam in turbine:

 Turbine inlet conditions :                  Turbine exit to condenser pressure:

  P3 = 2MPa, T3 = 1100°C                      P4 = P1 = 50 kPa

  h3 = 4889.1 KJ/kg                        s4 = s3 = 8.7842 KJ/kg.K  .. superheated

  s3 =  8.7842 KJ/kg.K                   h4 = hg = 2665.4 KJ/kg

- Apply energy balance for the turbine and determine the work output ( Wout ) produced by the turbine:

                     Wout = h3 - h4

                     Wout = 4889.1 - 2665.4

                     Wout = 2223.7 KJ/kg

- The net work-output obtained from the cycle ( W-net ) is governed by the isentropic processes of pump and turbine.

                  W_net = Wout - Win

                  W_net = 2223.7 -  567.93

                  W_net = 1655.77 KJ/kg   ... Answer

- The fraction of work generated by turbine is used to operate the pump. The a portion of Wout is used to drive the motor of the pump. The pump draws ( Win ) amount of work from pump. The ratio of work extracted from turbine ( n ) would be:

                 n = Win / Wout

                 n = 567.93 / 2223.7

                 n = 0.25539  ... Answer ( 25.5 % ) of work is used by pump

- The amount of heat loss in the condenser ( consider reversible process ). Apply heat balance for the condenser, using turbine exit and condenser exit conditions:

Sodium hydroxide, NaOH, is a very useful compound in the chemical industry. Sodium hydroxide is used to make soap, detergent, paper, and many other products. It is also used to clean drains, dissolve grease, and other materials.

For commercial convenience, one form of sodium hydroxide that is sold commercially is the saturated solution. This solution is M, which is approximately by mass sodium hydroxide.

To prepare L of M solution, we must first find the number of moles of NaOH that will be required.

Then we will find the volume of the saturated solution that is required to make this solution.
To find the number of moles of NaOH that will be required, we will use the formula:

\(N = C x V\)Where, N = number of moles of NaOH, C = concentration of the solution, and V = volume of the solution.

In this case, C = M, which is the concentration of the solution that we want to make. And V = L, which is the volume of the solution that we want to make.

So,

\(N = M x LV = N / MC = 40% = 40 / 100 = 0.4 M\)

Volume of the saturated solution required to prepare the M solution:

\(V = N / MV = 4.69 L\)

We will require approximately \(4.69 L\)of the saturated solution to prepare L of M solution.

Explanation:

1. The first thing we need to do is determine our knowns.

Knowns

2. The equation we need to use is one that relates Current, Voltage, and Power to one another.

Power = Current × Voltage

P = IV

3. Plug in all knowns to the equation and solve for Power.

P = 30 A × 220 V = 6600 Watts (or W)

4. Finally, we need to convert Watts to Horsepower.

1 hp = 745.7 W

6600 W × (1 hp / 745.7 W) = 8.85 hp

For the parallel fillet weld, the length required is 24.52mm and for transverse fillet welds, the longer fillet weld required is 24.39 mm and the length of the shorter fillet weld required is 6.13 mm.

The length of weld required to transmit a load between two plates depends on the type of weld used and the strength of the material being welded. For the given scenario:

Two parallel fillet welds:

The length of each fillet weld required can be calculated using the following formula:

L = (2 x F x P) / (0.7 x T)

where L is the length of each fillet weld, F is the applied force (54.5 KN), P is the perimeter of the weld (2 x length of the joint), T is the thickness of the plate (12.7 mm), and 0.7 is a constant. Substituting the values, we get:

L = (2 x 54.5 x 2) / (0.7 x 12.7) = 24.52 mm

Therefore, the length of each fillet weld required is 24.52 mm.

Two transverse fillet welds:

The length of each fillet weld required in this case can be calculated using the same formula as above, but with the perimeter of the weld being the sum of the lengths of the two sides being welded. Since the two fillet welds are transverse, their lengths will be different. Assuming one fillet weld is longer than the other, we can calculate their lengths as follows:

L1 = (F x P1) / (0.7 x T)

L2 = (F x P2) / (0.7 x T)

where L1 and L2 are the lengths of the two fillet welds, P1 and P2 are the perimeters of the two sides being welded, and all other variables are the same as before. We can assume that the longer fillet weld is on the side with the higher applied force, so we have:

P1 = 2 x length of joint

P2 = length of joint

Substituting the values, we get:

L1 = (54.5 x 2 x 2) / (0.7 x 12.7) = 24.39 mm

L2 = (54.5 x 1) / (0.7 x 12.7) = 6.13 mm

Therefore, the length of the longer fillet weld required is 24.39 mm and the length of the shorter fillet weld required is 6.13 mm.
