To find the length of the string, we can use the formula for the period of a pendulum T = 2π√(L/g) So the length of the string is 1.03 meters.


We are given the number of oscillations (29) and the time it takes (15 s), so we can find the period by dividing the time by the number of oscillations: T = 15 s / 29 = 0.517 s Now we can use this value to solve for the length of the string:
0.517 s = 2π√(L/9.81 m/s^2) Squaring both sides and solving for L, we get: L = (0.517 s / (2π))^2 * 9.81 m/s^2 = 1.03 m.


Finding the length of the string of a pendulum with a 105 g ball tied to it, pulled to an angle of 7.4 ∘ and released to swing, while a student with a stopwatch finds that 29 oscillations take 15 s, is that we can use the formula for the period of a pendulum to solve for the length of the string.

Drum Brakes: wheels are stopped by brake shoes that push out on a drum. Thus, option B is the correct option.

Drum brakes don't employ brake pads as its frictional substance. A drum brake system, on the other hand, uses a wheel cylinder with pistons to force brake shoes outward against the interior of a rotating drum. Your car will come to a halt as a result of this contact, which slows and stops the wheel's and brake drum's rotation.

The brake linings, which are friction materials, are pressed by the pistons onto the interior surfaces of the brake drums, which revolve with the wheels. The linings are forced onto the revolving drums, which causes the wheels to slow down and eventually come to a stop.

Answer:

33.1144 °C

Explanation:

From the information given;

The first step is to find the mean temperature \(T_m\) by using the formula:

\(T_m = \dfrac{T_i- T_\infty}{2}\)

where:

\(T_i\) = initial temperature = 40 °C

\(T_{\infty}\) = ambient temperature = 10 °C

\(T_m = \dfrac{(40+10)^0C}{2}\)

\(T_m = \dfrac{50^0C}{2}\)

\(T_m\)  = 25 °C

\(T_m\)  = (25 + 273) K

\(T_m\)  = 298 K ≅ 300 K

The following properties expressed below were obtained from the thermal physical properties table.

For soda-lime glass at the temperature of 300 K:

Density \(\rho_s = 2500 \ kg/m^3\)

Thermal conductivity \(k_s\) = 1.4 W/m.K

Specific heat \((c_p)_s\) = 750  J/kg.K

For bakelite at the temperature of 300 K:

Density \(\rho_B = 1300 \ kg/m^3\)

Thermal conductivity \(k_B\) = 1.4 W/m.K

Specific heat \((c_p)_B\) = 1465  J/kg.K

From these data; The next process is to find out the thermal diffusivity of each component.

To start with soda-lime glass by using the expression:

\(\alpha_s = \dfrac{k_s}{\rho_s ( c_p)_s}\)

\(\alpha_s = \dfrac{1.4 \ W/m.K}{2500 \ kg/m^3 \times 750 \\J/kg.K}\)

\(\alpha_s = 747 \times 10^{-9} \ m^2/s\)

For Bakelite: The thermal diffusivity is computed as:

\(\alpha_B = \dfrac{k_B}{\rho_B ( c_p)_B}\)

\(\alpha_B = \dfrac{1.4 \ W/m.K}{1300 \ kg/m^3\times 1465 \ J/kg.K}\)

\(\alpha_B = 735 \times 10^{-9} \ m^2/s\)

From the above two results, we will realize that \(\alpha _ s \simeq \alpha _B\)

Thus, as obvious as it is; we presume that the uniform thermal diffusivity

\(\alpha = 740 \times 10^{-9} \ m^2/s\)

However, the diameter of the sphere can be estimated by the summation of the diameter of the glass sphere \((D_1)\) with twice the thickness of the sphere (L)

i.e. \(D = D_1 + 2L\)

D = 25 mm + 2 (10 mm)

D = 45 mm

\(D = 45 \ mm ( \dfrac{10^{-3} \ m}{1 \ mm} )\)

D = 45 × 10⁻³ m

The expression for Biot Number can be estimated by using the formula:

\(Bi = \dfrac{hL}{k}= \dfrac{h(D/6)}{k}\)

Given that:

h = 30 W/m².k

D = 45 × 10⁻³ m

k = 1.4 W/m.K

Similarly, to estimate the Fourier No \(F_o\) by using the expression:

\(F_o = \dfrac{\alpha t}{(D/2)^2}\)

\(F_o = \dfrac{740 \times 10^{-9} \ m^2 /s \times 200 \ s}{( \dfrac{45 \times 10^{-3} m}{2})^2}\)

\(F_o = 0.292\)

It is obvious that \(F_o\) is > 0.2, thus, the validity of one term approximation is certain.

Again; the Biot Number is calculated by using the formula:

\(Bi = \dfrac{h(D/2)}{k}\)

\(Bi = \dfrac{30 \ W/m^2.K (\dfrac{45 \times 10^{-3 }\ m}{2}) }{1.4 \ W/m.k}\)

Bi = 0.482

Bi \(\simeq\) 0.5

We obtain the Eigen coefficient \(\xi_1\) as well as the coefficient for a sphere \(C_1\) using the Bi Number:

From one-term approximation of transient 1 heat conduction in the sphere;

\(\dfrac{T - 10^{0 } \C }{40^{0} \ C - 10^0 \ C} = 1.1441 \ exp \ ( -1.1656^2 \times 0.291)\)

\(\dfrac{T - 10^{0 } \C }{30^{0} \ C} = 0.77048\)

\(T - 10^{0 } \C = 30^{0} \ C \times 0.77048\)

\(T - 10^{0 } \C = 23.1144^0 \ C\)

T = (23.1144 + 10) °C

T = 33.1144 °C

In a split-tunnel VPN, only traffic destined for the organization's internal network goes through the VPN tunnel, while all other traffic goes directly to the internet. This means that traffic to and from external websites, applications, and services does not pass through the organization's firewall, reducing the load on the firewall and improving performance for users. Split-tunnel VPN architecture is typically used in large organizations with remote employees who need access to internal resources while still being able to access the internet for their personal needs.

To determine the type of the element with the given voltage and current functions, v(t) = 200 sin(200t + 30°) V and i(t) = 2 cos(200t - 30°) A, we should analyze the phase relationship between the voltage and current.

Step 1: Identify the phase angles of the voltage and current functions
Voltage: v(t) = 200 sin(200t + 30°)
Phase angle for voltage: 30°

Current: i(t) = 2 cos(200t - 30°)
Phase angle for current: -30°

Step 2: Calculate the phase difference
Phase difference = Phase angle for voltage - Phase angle for current
Phase difference = 30° - (-30°)
Phase difference = 60°

Step 3: Determine the type of the element based on the phase difference
- If the phase difference is 0°, the element is a resistance.
- If the phase difference is +90°, the element is a capacitance.
- If the phase difference is -90°, the element is an inductance.

Since the phase difference is 60°, which does not exactly match any of the above cases, the given element is a combination of different types of elements (e.g., a resistor and capacitor or a resistor and inductor). However, as it is closer to +90°, the dominant type of the element is likely a capacitance.

Answer:

1) 13 mg/liters

2)  72.22 mg/lit

3)  The Alkanity in raw water is not sufficient enough and the kinds of chemicals needed to enhance its acidity are

Explanation:

1) plot of turbidity versus dose and optimal dose of Alum ( mg/L )

Optimal dose of Alum = 13 mg/liters from the graph attached below

2) Theoretical amount of alkalinity consumed at the optimal dose can be calculated as follows

Alkanity is due to \(HCO^-_{3}\)

given optimal dose of Alum = 13 mg/liters for question 1

I mole of alum = 2 moles of AL(OH)3

666 grams of alum = 2*27 = 54 grams of AL(OH)3

hence 1 mole of \(AL^{+3}\)  = (13/54 ) mMole / lit

The  moles of HCO3 = 6 * \(\frac{13}{54}\)   because 1 mole of Alum reacts with 6 moles of HC03

[HCO3] as CaCO3 = 6 * (13/54) * 50

                               = 72.22 mg/lit (theoretical amount of alkalinity consumed)

3) The Alkanity in raw water is not sufficient enough and the kinds of chemicals needed to enhance its acidity are

The clutch slave cylinder is a component of a hydraulic clutch system that is responsible for disengaging the clutch when the driver depresses the clutch pedal.

When the clutch pedal is pressed, the master cylinder sends hydraulic fluid through the clutch line to the slave cylinder. The hydraulic fluid pressure then pushes a piston inside the slave cylinder, which in turn pushes against the clutch release arm. This releases the pressure on the clutch plate, allowing the engine to spin freely from the transmission. Therefore, to disengage the clutch, the clutch slave cylinder receives hydraulic fluid pressure from the master cylinder, which then pushes a piston to release the clutch.
