Answer:

yes, u can fold it but not whole like not straight but yea u can find it... btw is this ur school q or what

Yes, the back seats in a 2010 Toyota Prius hatchback can fold forward to create additional space for loading long items.

The Toyota Prius is a popular hybrid car that has been in production since 1997. The 2010 model year of the Prius hatchback features a versatile cargo area that includes 60/40 split-folding rear seats. This means that the back seats can be folded down in a 60/40 configuration to create additional space for longer items. By folding down both sides of the back seat, the cargo area can be extended from the trunk all the way up to the front seats. This allows for the transportation of larger items such as furniture or sporting equipment. The folding process is simple and can be completed by pulling a lever located on the side of the seat cushion. Once the seat is folded down, a flat loading surface is created, which makes it easy to load and transport items.

Given the following differential equation with initial conditions:\(`x + 2xdot + 2x = 0, x(0) = 0 mm, v(0) = 1 mm/sec`\). The closed-form expression for the response is:  \(`x(t) = e^(-t/2) [c1 cos(sqrt(3)/2)t + c2 sin(sqrt(3)/2)t]`\).

We can begin by using the characteristic equation method to solve the differential equation. The characteristic equation of the given differential equation is: \(`m^2 + 2m + 2 = 0`\)Using the quadratic formula:

\(`m = (-2 ± sqrt(2^2 - 4(1)(2)))/2`m = (-2 ± sqrt(-4))/2 = -1 ± i\)Using the solution method for complex roots, the solution to the differential equation is:x(t) = e^(-t/2) [c1 cos(sqrt(3)/2)t + c2 sin(sqrt(3)/2)t]Where, `sqrt(3)/2 = 60 degrees`.

The general solution is of the form: \(`x(t) = C1 e^(-t) cos(t) + C2 e^(-t) sin(t)`Since `x(0) = 0`\), we have:x(0) = C1 cos(0) + C2 sin(0) = 0C1 = 0, `x(t) = C2 e^(-t) sin(t)`

\(x(0) = C1 cos(0) + C2 sin(0) = 0C1 = 0, `x(t) = C2 e^(-t) sin(t)`\)Differentiating `x(t)` gives: `v(t) = dx/dt = C2 e^(-t) sin(t) - C2 e^(-t) cos(t)`Since `v(0) = 1 mm/sec`,\(`v(t) = dx/dt = C2 e^(-t) sin(t) - C2 e^(-t) cos(t)`Since `v(0) = 1 mm/sec`,\)

we have:v(0) = C2 sin(0) - C2 cos(0) = 1C2 = 1

Therefore, \(`x(t) = e^(-t) sin(t)`\)

\(`x(t) = e^(-t) sin(t)`\)

Hence, the closed-form expression for the response is: `x(t) = e^(-t/2) [c1 cos(sqrt(3)/2)t + c2 sin(sqrt(3)/2)t]`\(`x(t) = e^(-t/2) [c1 cos(sqrt(3)/2)t + c2 sin(sqrt(3)/2)t]`\).

It is possible to be convicted of a DUI (Driving Under the Influence) with a blood alcohol concentration (BAC) below the presumptive limit of 0.08%.

The specific legal limit for DUI can vary by jurisdiction, and in many places, there is a tiered system where different levels of impairment can lead to different charges. Even with a BAC below the legal limit, if there is evidence of impaired driving or if other factors indicate a person's ability to operate a vehicle safely was compromised, they can still be charged with and convicted of DUI. The decision ultimately depends on the laws and regulations of the specific jurisdiction in which the incident occurred.

Answer:

The correct HTML for creating a hyperlink is <a> symbol.

Answer:

The net work done is 272.38 kJ

Explanation:

The parameters given are;

Mass of water = 5 kg

p₁ = 20 bar

T₁ = 360°C

v₁ = 0.141147 m³/kg  

Process 1 to 2 = Constant pressure process

p₂ = 20 bar

Process 2 to 3 = Constant volume process

p₃ = 5 bar

Process 3 to 4 = Constant pressure process

Process 4 to 1 = Polytropic process pv = Constant

For Stage 1 to 2, we have;

p₂ = 20 bar

From the steam tables for superheated steam, we have;

T₂ = 212.385°C

v₂ = 0.0995805 m³/kg

Work done = p₂×(v₂ - v₁) = 2×10⁶ × (0.0995805 - 0.141147 ) = -83133 J/kg

For the 5 kg, we have;

\(W_{1-2}\) = -83133 J/kg × 5 = -415,665 J

Stage 2 to 3: Constant volume cooling

v₂ = v₃ = 0.0995805 m³/kg

p₃ = 5 bar

T₃ = 151.836°C

(0.0995805 - 0.00109256)/(0.374804 - 0.00109256) = 0.2635 liquid vapor mixture

Work done, \(W_{2-3}\) = 0

Stage 3 to 4: Constant pressure heating

p₃ = p₄ = 5 bar

v₄/T₄ = v₃/T₃

v₄ =  0.374804 m³/kg

T₄ = v₄×T₃/v₃ = 0.374804*(273.15 + 151.836)/0.0995805 = 1599.6 K = 1326.4 °C

Work done = p₄×(v₄ - v₃) = 5×10⁵ × (0.374804  - 0.0995805 ) = 137611.75 J/kg

For the 5 kg, we have;

\(W_{3-4}\) = 137,611.75  J/kg × 5 = 688,058.75 J

Stage 4 to 1: Polytropic process    

\(\dfrac{p_{4}}{p_{1}} = \left (\dfrac{V_{1}}{V_{4}} \right )^{n} = \left (\dfrac{T_{4}}{T_{1}} \right )^{\dfrac{n}{n-1}}\)

Which gives;

\(\dfrac{5}{20} = \left (\dfrac{0.141147 }{0.374804} \right )^{n}\)

n = log(5/20) ÷log(0.141147/0.374804) = 1.42

Work done, \(W_{pdv}\), is given as follows;

\(W_{pdv} = \dfrac{p_4 \times v_4 -p_4 \times v_4 }{n-1}\)

Which gives;

\(W_{pdv} = \dfrac{5\times 0.374804 -20\times 0.141147 }{1.42-1} = -2.259 \, J\)

For the 5 kg, we have;

\(W_{4-1}\) = -2.259 J/kg × 5 = -11.2967 J

The net work done, \(W_{Net}\), is therefore;

\(W_{Net}\) = \(W_{1-2}\)  + \(W_{3-4}\) + \(W_{4-1}\)

-415,665  + 688,058.75 -11.2967 = 272,382.45 J = 272.38 kJ.

True

Explanation:

Answer:

mechanical engineer is the best answer

Answer:

a. 27.65 N b. 5.93 cm/s c. 0.03n where n = 1,2,3....

Explanation:

a. Since Young's Modulus E = stress/strain = σ/ε and σ = εE, we find the stain in the steel wire by finding its strain at 20°C.

Now Δl = lαΔθ where l = length of steel wire = 1.000 m, α = coefficient of linear expansion of steel = 11.0 × 10⁻⁶ C⁻¹ and Δθ = change in temperature = 20 °C - 60 °C = -40 °C

The strain  ε = Δl/l = αΔθ = 11.0 × 10⁻⁶ C⁻¹ × -40 °C = -4.4 × 10⁻⁴

σ = T/A= εE, where T = tension in steel wire and A = cross-sectional area of steel wire

T = εEA = εEπd²/4 where d = diameter of wire = 2.000 mm = 2 × 10⁻³ m

So,

T = εEπd²/4

= 4.4 × 10⁻⁴ × 2× 10¹⁰ Pa × π ×  (2 × 10⁻³ m )²/4

= 27.65 N

b. The velocity of the travelling wave at this lower temperature is

v = √(T/μ) where μ = mass per unit length = ρl where ρ = density of steel wire = 7.86 × 10³ kg/m³ and l = length of wire = 1.000 m

v = √(T/μ)

= √(T/ρl)

= √(27.65 N/(7.86 × 10³ kg/m³ × 1.000 m))

= √(27.65 N/7.86 × 10³ kg/m²)

= √(0.3517 × 10⁻² N/kg/m²)

= 0.05931 m/s

≅ 0.0593 m/s

= 5.93 cm/s

c. To find the allowable frequencies, we first find the fundamental frequency f₀ = v/2l

= 0.0593 m/s ÷ (2 × 1 m)

= 0.0593 m/s ÷ 2

= 0.0297 Hz

≅ 0.03 Hz

So, the allowable modes of frequency are multiples of f₀, that is fₙ = nf₀ where n = 1,2,3....

So, fₙ = 0.03n Hz where n = 1,2,3....

The maximum stress in a cantilever horizontal cylindrical shaft acted upon by a vertical force and a torque at the free end is at the lower surface of the shaft, at the free end.

The vertical force causes a bending moment in the shaft, which is greatest at the free end. The torque also causes a twisting moment in the shaft, which is also greatest at the free end.

The combination of these two moments creates a maximum tensile stress at the lower surface of the shaft, and a maximum compressive stress at the upper surface of the shaft.

The maximum stress can be calculated using the following formula:

σ_max = Mc / I

where:

σ_max is the maximum stress

M is the bending moment

c is the distance from the neutral axis to the surface of the shaft

I is the moment of inertia of the shaft

In this case, the distance from the neutral axis to the surface of the shaft is equal to the radius of the shaft. Therefore, the maximum stress can be written as:

σ_max = Mc / (πr^2)

The maximum stress occurs when the bending moment and the torque are at their maximum values. The maximum bending moment occurs when the vertical force is applied at the center of the shaft, and the maximum torque occurs when the torque is applied at 90 degrees to the vertical force.

Therefore, the maximum stress in the shaft occurs at the lower surface of the shaft, at the free end, where the bending moment and the torque are both at their maximum values.

Ceramics are created by combining different materials to make a workable mass, which is then shaped and fired to create a finished piece.

Clay is a natural material used to make ceramics.

To bond pieces of clay together, a slip is used.

When clay is bonded, the joint becomes stronger.

Roughening the edges of clay with a wooden or metal modeling tool is recommended before cementing the clay with slip.

Roughening the edges creates a better bond between the two pieces of clay and helps to make a stronger joint.

A better bond means that the pieces will stick together better, which makes the joint stronger.

Roughening the edges can be done with a wooden or metal modeling tool.

The tool is used to score the edges of the clay by creating shallow scratches.

This is done to increase the surface area of the clay and to give the slip something to grip onto.

Once the edges are roughened, the slip can be applied and the pieces can be cemented together.

In conclusion, roughening the edges of clay before cementing with slip is highly recommended for a stronger joint.

The process can be carried out using a wooden or metal modeling tool.

The roughening creates a better bond between the two pieces of clay and helps to make a stronger joint.

Answer:

1.887 minutes

Explanation:

We are given k = 0.07 dm3 /mol*min at 300 K and E = 20 kcal/mol = 20000 cal/mol

To solve this, first of all let's calculate the rate constant(k);

For this question, The formula is;

K(t) = k(300K) × exp[(E/R)((1/300) - (1/T2))]

R is gas constant = 1.987 cal/mol.K

For temperature of 70°C which is = 70 + 273K = 343K, we have;

K(343) = 0.07 × exp[(20000/1.987)((1/300) - (1/343))]

K(343) = 4.7 dm³/mol.min

The design equation is;

dX/dt = -(rA/C_Ao) = K•(C_Ao)²•(1 - X)²/(C_Ao) = (KC_Ao)(1 - X)²

Since there is no change in volume by cause of the state at which the reaction is carried out, that is liquid. Thus, integrating and solving for time for a 90% conversion we obtain;

(0.9,0)∫dX/(1 - X)².dX = (KC_Ao)((t, 0)∫dt

So, we'll get;

0.9/(1 - 0.9) = 4.77 × 1 × t
