Answer:

Truss bridge, bridge with its load-bearing structures composed of a series of wooden or metal triangles, known as trusses. Given that a triangle cannot be distorted by stress, a truss gives a stable form capable of supporting considerable external loads over a large span.

Explanation:

Load-bearing capacity of truss bridges is huge due to the structure of interconnecting triangles. The structure effectively manages both compression and tension by spreading the load from the roadway throughout its intricate structure

Answer:

The Reynolds number determines what type of regime is laminar or turbulent in a flow pattern.

Explanation:

The Reynolds number determines what type of regime is laminar or turbulent in a flow pattern.

In the laminar regime R_D <2300 the flow is ordered and has an envelope predicted by the expressions

In the turbulent regime R_D> 2900 the flow has vortices and is extremely irregular

in the intermediate values ​​it is in a transition regime

Answer:

The capacitance of the other capacitor is 1333.3 pF.

Explanation:

C' = 200 pF, V' = 100 V, C'' , V''= 0

Common potential, V = 60 V

Use the formula of the common  potential

[tex]V = \frac{C' V' + C'' + V''}{C'+ C''}\\\\60 = \frac{200\times 100 + 0}{200 + C''}\\\\1200+ 6 C''= 2000\\\\C'' = 1333.3 pF[/tex]

Answer:

Explanation:

The formula for this is

[tex]n_1sin\theta_1=n_2sin\theta_2[/tex] where the index of refraction of air is 1.00. Filling in and solving for n2:

1.00sin(25) = n₂sin(13) and

1.00(.423) = n₂(.225) and

[tex]\frac{1.00(.423)}{.225}=n_2[/tex] so

Answer:

The answer to this is FALSE.

Answer:

Answer:

Because the unit of area depends upon the other fundamental units.

Explanation:

Unit of Area = m^2

actual metre is the unit of length.

so metre × metre makes ?^2

It is true that the metal will begin to emit electrons at varied speeds depending on the intensity of the light when it is struck at a minimal wavelength.

When a waveform signal is propagated in space or over a wire, the wavelength is the separation between two identical locations (adjacent crests) in the adjacent cycles.

If you are employing light with a high enough frequency, the number of electrons ejected grows as the light source's brightness rises.

The velocity of the expelled electrons increases as the frequency is raised above the threshold.

Thus, the metal will begin to emit electrons at varied speeds depending on the intensity of the light when it is struck at a minimal wavelength.

Complete question:

A hydraulic jack is used to lift a car by applying a force of 120N at the pump piston, if the area of the ram and pump piston are 100cm squared and 1m squared respectively. What is the weight of the car?

Answer:

the weight of the car is 1.2 N

Explanation:

Given;

applied force, F₁ = 120 N

area of the effort (pump), A₁ = 1 m²

area of the load (ram), A₂ = 100 cm² = 1 x 10⁻² m²

let the weight of the car = F₂

The applied pressure is constant and the following equations can be used to calculate the weight of the car.

[tex]P = \frac{F_1}{A_1} = \frac{F_2}{A_2} \\\\F_2 = \frac{F_1 \times A_2}{A_1} \\\\F_2 = \frac{120 \times (1\times 10^{-2})}{1} \\\\F_2 = 1.2 \ N[/tex]

Therefore, the weight of the car is 1.2 N

Answer:

(4) 8.5 m/s

Explanation:

You add both the meters together and both the seconds together and then divide them both.

Answer:

(4) 8.5 m/s

Explanation:

Total distance = 35 + 50 = 85m

Total time = 4 + 6 = 10sec

average speed = total distance/ total time

ave. speed = 85/10 = 8.5 m/s

Answer:

the initial velocity of the particle is 5 cm/s

Explanation:

Given initial displacement as, s = 6t² + 5t - 5

s is measured in "cm"

t is measured in "seconds"

Velocity is the rate of change of displacement with time. Expressed as follows;

[tex]v = \frac{ds}{dt} = 12t + 5[/tex]

for initial velocity, time (t) = 0

v = 12(0) + 5

v = 5 cm/s

Therefore, the initial velocity of the particle is 5 cm/s

Answer:

Total: 200 meters, Displacement: 100 meters South

Explanation:

First, add up the meters traveled to get the total distance.

50m + 150m = 200m

Lastly, displacement is the shortest distance from the initial position to the final position. The person first walked 50 meters north but then traveled 150 meters south. Therefore, their displacement was 100 meters south.

50m - 150m = -100m

(Note: Directions are vectors. North and East are positive vectors while South and West are negative)

Answer:

3.33 m/s

Explanation:

1600 divided by 8 comes out to 200, so supposing we're measuring the speed in terms of Meters Per Second, we would need to divide 200 by 60 to take account of the individual seconds as opposed to simply 200 meters per minute.

There are two sets of resistors joined in series in a circuit. Set 1 has two resistors of 10Ω and 40Ω in parallel combination. Set 2 has three resistors of 20 Ω, 30 Ω and 60 Ω in parallel combination. A potential difference of 12 V is applied across the combination.

FOR DIAGRAM REFER ATTACHMENT!

[tex]{\bold{\green{\star{\red {Part \: 1:- The \: Total \: Resistance }}}}}[/tex]

First we calculate the total resistance of each parallel combination:-

FIRST SET Contains two resistors of 10Ω and 40Ω

so total resistance-->

[tex] \frac{1}{Rs1} = \frac{1}{R1} + \frac{1}{R2} \\ \\ \frac{1}{Rs1} = \frac{R1 + R2}{R1R2} \\ \\ \frac{1}{Rs1} = \frac{10 + 40}{400} \\ \\ \frac{1}{Rs1} = \frac{50}{400} \\ \\ \frac{1}{Rs1} = \frac{1}{8} \\ \\ Rs1 = 8 Ω[/tex]

SECOND SET Contains three resistors of 20 Ω, 30 Ω and 60Ω

so total resistance-->

[tex] \frac{1}{Rs2} = \frac{1}{R1} + \frac{1}{R2} + \frac{1}{R3} \\ \\ \frac{1}{Rs2} = \frac{R1 + R2 +R3}{R1R2R3} \\ \\ \frac{1}{Rs2} = \frac{3+ 2 + 1}{60} \\ \\ \frac{1}{Rs2} = \frac{6}{60} \\ \\ \frac{1}{Rs2} = \frac{1}{10} \\ \\ Rs2 = 10Ω[/tex]

Now by having Total Resistance of Set one and set two we can add them by series formula.

[tex]R = Rs1 + Rs2 \\ R = 8 + 10 = 18 \: Ω[/tex]

[tex]{\bold{\green{\star{\orange{Part \: 2:- The \: Total \: Current \: Flowing \: In \: The \: Circuit. }}}}}[/tex]

Total Resistance of the circuit = 18 Ω

Potential Difference Of the circuit = 12 V

Answer:

Current in the circuit(I) = 0.5 ampere

Explanation:

Given:

Number of resistors = 2 (10 ohm each)

Series of resistors

EMF = 10 volt

Find:

Current in the circuit(I)

Computation:

Total resistance in series = R1 + R2

Total resistance in series = 10 + 10

Total resistance in series = 20 ohm

Current in the circuit(I) = EMF / Total resistance in series

Current in the circuit(I) = 10 / 20

Current in the circuit(I) = 0.5 ampere

Answer:

[tex]25\%[/tex] of the wavelength is between resonances in a closed end tube.

Explanation:

In an one end closed tube, the fundamental resonance occurs when a node is created at the closed end and an antinode is created in the open end.

Thus, for fundamental resonance, the entire length of the tube encloses one-fourth of the wavelength of the standing wave.

The formula to calculate the percentage of the wavelength in a closed end tube is given by

[tex]f=\frac{L}{\lambda}\times100\%........................(1)[/tex]

Here, [tex]f[/tex] is the required percentage, [tex]L[/tex] is the length of the tube and [tex]\lambda[/tex] is the wavelength of the standing wave.

Substitute [tex]\frac{\lambda}{4}[/tex] for [tex]L[/tex] into equation (1) o calculate the required percentage.

[tex]f=\dfrac{\frac{\lambda}{4}}{\lambda}\times100\%\\~~~=25\%[/tex]
