Answer:

Magnitude of the velocity = 16.82 m/s

Angular direction, θ = 52.41°

Explanation:

As given ,

mass of bullet, m₁= 50g = 0.05 kg

speed of bullet , u₁ = 600 m/s

mass of the block , m₂ = 4 kg

speed of the block before collision , u₂ = 12 m/s

direction , θ = 30°

Now,

Assume that the combined velocity of bullet and block after collision = v

and the direction = θ

Now, from the conservation of momentum in x - direction :

m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) vₓ

where v = final velocity after collision

u₁ = initial velocity of bullet before collision = 0

m₁ = mass of the bullet before collision = 0.05 kg

u₂  = velocity of block before collision = 12 cos(30° )

m₂ = mass of block before collision

m₁ + m₂ = combined mass of bullet and block after collision = 0.05 + 4

∴ we get

0.05 (0) + 4(12 cos(30° ) ) = ( 0.05 + 4 ) vₓ

⇒ 0 + 4(6√3) = 4.05 vₓ

⇒24√3 = 4.05 vₓ

⇒vₓ = 10.26 m/s

Now, from the conservation of momentum in y - direction :

m₁ u₁ + m₂ u₂ = ( m₁ + m₂ ) \(v_{y}\)

where v = final velocity after collision

u₁= initial velocity of bullet before collision = 600

m₁ = mass of the bullet before collision = 0.05 kg

u₂  = velocity of block before collision = 12 sin(30° )

m₂= mass of block before collision

m₁+ m₂= combined mass of bullet and block after collision = 0.05 + 4

∴ we get

0.05 (600) + 4(12 sin(30° ) ) = ( 0.05 + 4 ) \(v_{y}\)

⇒ 30 + 4(6) = 4.05 \(v_{y}\)

⇒30 +24 = 4.05 \(v_{y}\)

⇒54 = 4.05 \(v_{y}\)

⇒\(v_{y}\) = 13.33 m/s

Now, the magnitude of the velocity = √vₓ² + \(v_{y}\)² = √(10.26)² + (13.33)²

                                                           = √105.26 + 177.68

                                                           = √282.95 = 16.82

The angular direction, θ =  \(tan^{-1}\)(\(\frac{v_{y} }{v_{x} }\)) =  \(tan^{-1}\)(\(\frac{13.33}{10.26}\)) = \(tan^{-1}\)(1.299) = 52.41°

Answer: a. 0.4667

b. 0.4667 and C 0.0667

Explanation:

Given Data:

N = population size (10)

n = random selection (2)

r = number of observations = 7

Therefore

f(y) = ( r/y ) ( N - r / n - y ) / ( N /n )

When y = 1

f(1) = ( 7/1 ) ( 10 - 7 / 2 -1 ) / ( 10/2 )

= 7 / 15

= 0.4667

When y = 2

f(2) = ( 7/2 ) ( 10 - 7 / 2 -2 ) / ( 10/2 )

= 7 / 15

= 0.4667

When y = 0

f(0) = ( 7/0 ) ( 10 - 7 / 2 -0) / ( 10/2 )

= 1 / 15

= 0.0667

Solution :

A = πD² / 4 = π(1²) / 4

A = 0.785 ft²

Velocity of water :

U = Q / A = 5.6 / 0.785

U = 7.134 ft/s

Friction loss due to pipe length :

Re = UD / v = (7.134)(1) / (0.511 × 10^(-5))

Re = 1.4 × 10⁶

(From Moody Chart, We Get f = 0.015)

Answer:

Option B: False

Explanation:

A heat engine is a device which operates in a manner that heat is converted into mechanical work.

A simple example of a heat engine is a drinking bird. The oscillatory motion of the drinking bird is as a result of the thermal expansion and contraction of a chemical compound in its beak, which creates an imbalance in its position of equilibrium. This causes it to oscillate.

Heat engines usually work by extracting heat once there is a temperature gradient available in the system and using it to perform work. Another good example is the internal combustion engine. It extracts heat from the explosion of the burning fuels and uses it to power the car.

True, when calculating depreciation using the declining balance (DB) method and the sum-of-the-years' digits (SOYD) method, the salvage value is not directly used in the calculation of the depreciation charge.

In the declining balance method, depreciation is calculated by applying a constant depreciation rate to the net book value of the asset (cost minus accumulated depreciation). The depreciation charge decreases over time, as the net book value decreases, but the salvage value is not directly factored into the calculation. In the sum-of-the-years' digits method, depreciation is determined by multiplying the asset's cost by a fraction, with the numerator being the remaining useful life of the asset, and the denominator being the sum of the years' digits. The salvage value is not used in the calculation of the depreciation charge. However, it is essential to monitor the accumulated depreciation to ensure that the asset's net book value does not fall below the salvage value.

Both the DB and SOYD methods are accelerated depreciation methods that result in higher depreciation expenses in the early years of an asset's life, reflecting the idea that an asset's value declines more rapidly in its initial years. Although the salvage value is not directly used in the calculations, it is essential for determining the asset's net book value and ensuring it doesn't fall below the salvage value.

Explanation:

Answer:

10.203 Volts

Explanation:

For this problem, we need to understand that a series resistive circuit is simply a circuit with some type of voltage source and some resistors, in this case, R1 and R2.

First, we need to find the voltage in the circuit.  To do this, we need to find the total resistance of the circuit.  When two resistors are in series, you sum the resistance.  So we can say the following:

R_Total = R1 + R2

R_Total = 570 Ω + 560 Ω

R_Total = 1130 Ω

Now that we have R_Total for the circuit, we can find the voltage of the circuit by using Ohm's law, V = IR.

V_Total = I_Total * R_Total

V_Total = 17.9 mA * 1130 Ω

V_Total = 20.227 V

Now that we have V_Total, we can find the voltage drop across each resistor by using Ohm's law once more.  Note, that since our circuit is series, both resistors will have the same current (I.e., I_Total = I_1 = I_2).

V_Total = V_1 + V_2

V_Total = V_1 + I_2*R2

V_Total - I_2*R2 = V_1

20.227 V - (17.9 mA * 560 Ω) = V_1

20.227 V - (10.024 V) = V_1

10.203 V = V_1

Hence, the voltage drop across R1 is 10.203 Volts.

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.

The RMR value is 413.15, which indicates that the rock mass is of excellent quality.

The most important geologic criteria are combined by RMR, which depicts them as a single, comprehensive indicator of rock mass quality.

Based on the given parameters, we can use the Rock Mass Rating (RMR) method to classify the rock mass.

The RMR value is given by the formula:

RMR = 70Q + 10G + 5F + 8L + 7S - 3W

Using the given parameters, we can calculate the RMR value as follows:

Q = 10 x \((RQD/10)^{1/2\) x (Jn + Ja + Jw + Jr + Jsr)

Where Jn, Ja, Jw, Jr, and Jsr are the joint sets orientations, number, water pressure, roughness, and spacing rating, respectively.

Since we do not have information about the joint orientations and roughness, we can assume that they have a neutral effect on the RMR value, which means that Jn=Ja=Jr=1 and Jw=Jsr=0.5.

Therefore,

Q = 10 x\((55/10)^{1/2\) x (1 + 1 + 0.5 + 1 + 0.5) = 57.45

G = 0 (since joint water pressure is nil)

F = 5 (since the joint condition is open joints filled with gouge)

L = 8 - 2.6 x log10(0.5) = 5.44

S = 7 (since the joint condition is filled with 5mm gouge)

W = 0 (since joint water pressure is nil)

Thus, RMR = 7057.45 + 100 + 55 + 85.44 + 77 - 30 = 413.15

Adding certain materials to face electrode fluxes can significantly affect the arc resistance.

When it comes to face electrode fluxes, adding a flux coating can significantly influence the arc resistance. Flux coatings are commonly applied to welding electrodes to improve their performance and enhance the quality of the weld. These coatings are composed of various materials that serve different purposes, such as stabilizing the arc, reducing spatter, protecting against oxidation, and controlling the penetration depth.

Flux coatings contribute to arc resistance by creating a more stable arc during the welding process. They contain substances that generate gases or other components when heated, forming a protective atmosphere around the arc. This shielding effect minimizes the exposure of the arc to the surrounding air, preventing atmospheric contaminants from negatively affecting the welding process.

Moreover, flux coatings can also alter the chemical composition of the weld pool, thereby modifying its properties. By introducing specific elements or alloys into the electrode flux, they can enhance the strength, ductility, and corrosion resistance of the resulting weld. This can be particularly beneficial when welding dissimilar metals or when specific mechanical or chemical characteristics are desired.
