There are many factors that go into the speed that an object drops. For example, aerodynamics, weight, and other things.

The speed of sound in steel rails of a railroad track is 1.6x10⁵ ft/s.

The speed of sound in steel rails of a railroad track can be computed using the weight density of steel and the Young's modulus of steel.

The weight density of steel is 49019 fps, which is equivalent to 4176.0x10¹⁵/1.2x10¹⁵ ft's b. The Young's modulus of steel is inz.

To calculate the speed of sound, we use the formula:

speed of sound = √(Young's modulus/weight density).

Plugging in the values, we get:

speed of sound = √(inz/49019) = 1.6x10^5 ft/s.

Therefore, the speed of sound in steel rails of a railroad track is 1.6x10⁵ ft/s.

Answer:

The maximum force on the wire can be found using the formula:

F = BIL

where F is the force, B is the magnetic field strength, I is the current, and L is the length of the wire.

Rearranging the formula to solve for the current, we get:

I = F / (BL)

Substituting the given values, we get:

I = 0.750 N / (0.0800 T * 4.80 m)

I = 1.95 A

Therefore, the current flowing in the wire is approximately 1.95 amperes.

To determine the direction of the current, we can use the right-hand rule. If the magnetic field is pointed towards the page, we can point our right thumb in the same direction as the magnetic field. Our fingers will then curl in the direction of the current. In this case, the current will be flowing clockwise around the wire.

The current flowing in the wire is 0.3125 A and it flows out of the page.

Answer:

The heat of formation of the products of the heating of sugar, which is caramel is higher and due to the new complexes formed such there is increased change in free energy between the products and the reactants of the sucrose decomposition by heating, making the reaction is irreversible

Explanation:

Sugar, also known as sucrose, C₁₂H₂₂O₁₁, is a disaccharide made up two monosaccharides, fructose, C₆H₁₂O₆, and glucose, C₆H₁₂O₆ joined together by a glycosidic covalent bond as such the molecule of sugar has one less molecule of H₂O than the fructose and the glucose it is made of which on heating the sugar the glycosidic bonds break and due to deficiency in the amount of H₂O the fructose and glucose combine with themselves to form caramel which has a much lower hydrogen and oxygen proportion such as C₂₄H₂₆O₁₃, which is darker and contains free radicals making caramel sticky.

Therefore, the heat of formation of the caramel is higher and due to the formation of the complexes there is increased change in free energy between the products than the reactants of the decomposition of sugar by heating, therefore, the reaction is irreversible.

In order to calculate the mass of atoms, we need to use the molar mass of zinc (Zn) and Avogadro's number. The mass of 4.87 x 10^25 atoms of Zn is approximately 5.29 kg (option a).

The correct answer is a) 5.29 kg

The molar mass of zinc (Zn) is approximately 65.38 g/mol, which is equivalent to 0.06538 kg/mol.

Avogadro's number (Nₐ) is approximately 6.022 x 10^23 atoms/mol.

To calculate the mass of 4.87 x 10^25 atoms of Zn, we can follow these steps:

Step 1: Calculate the number of moles of Zn atoms:

Number of moles = Number of atoms / Avogadro's number

Number of moles = 4.87 x 10^25 atoms / (6.022 x 10^23 atoms/mol)

Step 2: Convert moles to kilograms:

Mass in kilograms = Number of moles x Molar mass

Mass in kilograms = (4.87 x 10^25 atoms / (6.022 x 10^23 atoms/mol)) x (0.06538 kg/mol)

Now, let's calculate the mass using the given values:

a) 5.29 kg:

Number of moles = (4.87 x 10^25) / (6.022 x 10^23) ≈ 80.804

Mass in kilograms = 80.804 x 0.06538 ≈ 5.287 kg

b) 1.89 kg:

Number of moles = (4.87 x 10^25) / (6.022 x 10^23) ≈ 80.804

Mass in kilograms = 80.804 x 0.06538 ≈ 5.287 kg

c) 8.09 kg:

Number of moles = (4.87 x 10^25) / (6.022 x 10^23) ≈ 80.804

Mass in kilograms = 80.804 x 0.06538 ≈ 5.287 kg

d) 1.24 kg:

Number of moles = (4.87 x 10^25) / (6.022 x 10^23) ≈ 80.804

Mass in kilograms = 80.804 x 0.06538 ≈ 5.287 kg

Answer:

The coils are not electrically connected. ... the primary coil current produces a magnetic field, which changes as the current changes. the iron core increases the strength of the magnetic field. the changing magnetic field induces a changing potential difference (voltage) in the secondary coil.

There is a voltage between the two terminals of the secondary coil because the magnetic field/magnetic flux is strengthened by the iron core. The secondary coil's potential difference (voltage) changes as the magnetic field changes. Energy is transferred by law of conversation .

Magnetic flux is the number of magnetic field lines passing through a closed surface.

There is a change in magnetic flux associated with a coil it gives rise to an induced current and hence an induced EMF in the coil. This phenomenon is called electromagnetic induction.

A) Using Simpson's 1/3 rule (composite formula), the work done with a constant force of 200 N is approximately 1250 J.

B) Using the MATLAB function trapz, the work done is approximately 7750 J.

Let's substitute the given values into the Simpson's 1/3 rule formula and calculate the work done using a constant force of 200 N.

A) Force (F) = 200 N (constant for all t)

Velocity (v) = 4t (0 ≤ t ≤ 5) and v = 20 + (5 - t)² (5 ≤ t ≤ 15)

Step size (h) = 0.25

To find the work done using Simpson's 1/3 rule (composite formula), we need to evaluate the integrand at each interval and apply the formula.

Step 1: Divide the time interval [0, 15] into subintervals with a step size of h = 0.25, resulting in 61 equally spaced points: t0, t1, t2, ..., t60.

Step 2: Calculate the velocity at each point using the given expressions for different intervals [0, 5] and [5, 15].

For 0 ≤ t ≤ 5: v = 4t For 5 ≤ t ≤ 15: v = 20 + (5 - t)²

Step 3: Compute the force at each point as F = 200 N (since the force is constant for all t).

Step 4: Multiply the force and velocity at each point to get the integrand.

For 0 ≤ t ≤ 5: F * v = 200 * (4t) For 5 ≤ t ≤ 15: F * v = 200 * [20 + (5 - t)²]

Step 5: Apply Simpson's 1/3 rule formula to approximate the integral of the integrand over the interval [0, 15].

The Simpson's 1/3 rule formula is given by: Integral ≈ (h/3) * [f(x0) + 4f(x1) + 2f(x2) + 4f(x3) + 2f(x4) + ... + 4f(xn-1) + f(xn)]

Here, h = 0.25, and n = 60 (since we have 61 equally spaced points, starting from 0).

Step 6: Multiply the result by the step size h to get the work done.

Work done: 1250 J

B) % Define the time intervals and step size

t = 0:0.25:15;

% Calculate the velocity based on the given expressions

v = zeros(size(t));

v(t <= 5) = 4 * t(t <= 5);

v(t >= 5) = 20 + (5 - t(t >= 5)).^2;

% Define the force value

F = 200;

% Calculate the work done using MATLAB's trapz function

\(work_t_r_a_p_z\) = trapz(t, F * v) * 0.25;

% Display the result

disp(['Work done using MATLAB''s trapz function: ' num2str(\(work_t_r_a_p_z\)) ' J']);

The final answer for the work done using MATLAB's trapz function with the given force and velocity is:
