what is correct answer .​

Answer:

Numerical Methods are mathematical way to solve certain problems.Whether the equations are linear or nonlinear, efficient and robust numerical methods are required to solve the system of algebraic equations.

Analytical solutions are exact solutions based on mathematical principles.

However, the governing partial differential equations of fluid flow are complex and cannot be solved by analytical means. The partial differential equations are therefore converted into a system of algebraic equations that are subsequently solved through numerical methods to provide approximate solutions to the governing equations.

Although we rarely reach on exact answer , we can get really close to the exact answer much quicker than solve analytically.

Answer:

20 ns

Explanation:

Since the deflection plates are in series with the resistor, the deflection plates act as a capacitor.

So, the set-up is a series RC circuit.

The voltage across the deflection plates V =

[tex]V = V_{0}(1 - e^{-\frac{t}{RC} } )[/tex]

where V₀ = voltage applied = 100 V, R = resistance of resistor = 1075 Ω and C = capacitance of deflection plates and t = time to reach 65 V

The capacitance of the deflection plates C = ε₀A/d where ε₀ = permittivity of free space = 8.854 × 10⁻¹² F/m, A = area of deflection plates = 10 cm × 2 cm = 20 cm² = 20 × 10⁻⁴ m² and d = distance between deflection plates = 1 mm = 1 × 10⁻³ m.

So, C = ε₀A/d

C =  8.854 × 10⁻¹² F/m × 20 × 10⁻⁴ m²/1 × 10⁻³ m

C =  177.08 × 10⁻¹⁶ Fm/1 × 10⁻³ m

C =  177.08 × 10⁻¹³ F

C = 17.708 × 10⁻¹² F

Since we require the time it takes the capacitor to reach 65 Volts, V = 65 and we make t subject of the formula,

So, [tex]V = V_{0}(1 - e^{-\frac{t}{RC} } )[/tex]

[tex]\frac{V}{V_{0}} = (1 - e^{-\frac{t}{RC} } )\\e^{-\frac{t}{RC} } = 1 - \frac{V}{V_{0}}[/tex]

taking natural logarithm of both sides, we have

-t/RC = ㏑(1 - V/V₀)

t = -RC㏑(1 - V/V₀)

Substituting the values of the variables into the equation, we have

t = -RC㏑(1 - V/V₀)

t = -1075 Ω × 17.708 × 10⁻¹² F㏑(1 - 65 V/100 V)

t = -19036.1 × 10⁻¹² ΩF㏑(1 - 0.65)

t = -19036.1 × 10⁻¹² ΩF㏑(0.35)

t = -19036.1 × 10⁻¹² × -1.0498 s

t = 19984.5189 × 10⁻¹² s

t = 1.99845189 × 10⁻⁸ s

t = 19.99845189 × 10⁻⁹ s

t ≅ 20 × 10⁻⁹ s

t ≅ 20 ns

So, the time it takes the potential difference between the deflection plates to reach 65 V is 20 ns.

Newton first law state that anything in motion or rest will remain in motion or in rest until an external force is applied

Newton third law of motion state that every action have equal and opposite reaction

Answer:

Newton's laws of motion relate an object's motion to the forces acting on it. In the first law, an object will not change its motion unless a force acts on it. ... In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

Answer:

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.

Explanation:

Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment. Practical resistors as discrete components can be composed of various compounds and forms. Resistors are also implemented within integrated circuits.

The electrical function of a resistor is specified by its resistance: common commercial resistors are manufactured over a range of more than nine orders of magnitude. The nominal value of the resistance falls within the manufacturing tolerance, indicated on the component.

The centripetal force on the truck can be determined from the mass, velocity and the radius of the circular path. The centripetal force acting on the truck is 500 N. Hence, option A is correct.

Centripetal force is a type force acting on an object traveling through a circular path. The centripetal force is the rotational analogue of the linear force.

The centripetal force acting on an object is related to the mass, velocity and radius of the circular path is given by:

Fc =  mv ²/r

Given that, mass of truck = 20 Kg

radius of circle = 4 m

velocity = 10 m/s

Then, centripetal force Fc = 20 kg ×  10² m/s / 4 m = 500 N

Therefore, the centripetal force on the truck is 500 N.

Friction can be defined as a type of force that prevents two smooth surfaces from sliding together on each other. Friction is a strong force that opposes motion when two surfaces come in contact with each other.

The different methods/ways to reduce friction include;

- Application of lubricant to surfaces

- Streamlined bodies; this goes a long way in preventing friction between two bodies.

- Decrease in weight; reducing the amount of weight on a substance can also help to reduce friction

- Applying wheels to objects that move/roll on the ground.

Answer:

100 m.

Explanation:

At first the car was stationary, so its inicial velocity is zero. Considering its inicial position 0 m and using the Equation of motion for the position:

X(t) = Xo + vo.t +a[tex]t^{2}[/tex]/2 , vo=0, Xo=0, a=2m/[tex]s^{2}[/tex]

X(10) = (2 x [tex]10^{2}[/tex])/2 = 100 m.

Answer:

given,

load = 400 N

effort = 100 N

load distance = 20 cm

we know that ,

E*Ed = L*Ld

=100 N* Ed = 400N * 20 cm

=100N * Ed = 8000N/cm

= Ed =( 8000N/cm ) / 100N

= Ed = 80 cm

b. soln.

given,

load = 600 N

load distance = 2 m

effort = 300 N

effort distance = ?

we know that ,

= E *Ed = L * Ld

= 300N * Ed = 600N * 2 m

= 300N * Ed = 1200N/m

=Ed =( 1200N/m ) / 300 N

= Ed = 4 m

C. soln.

given,

load = 600 N

load distance =20 cm

Efficiency = ?

we know that ,

= E *Ed = L *Ld

= 200N * Ed = 600 N * 20 cm

=200 N *Ed = 12000 N/cm

=Ed = ( 12000 N/cm) / 200 N

= Ed = 60 cm

Also,

M.A = load / effort

=600 N / 200 N

= 3

V.R = Ed/ Ld

= 60 cm / 20 cm

= 4

efficiency = ( M.A / V.R ) 100 %

= ( 3 / 4 ) 100%

= 75 %
