The mass of the child on the left is 45 Kg.

Hence, the correct option is D.

We can use the principle of moments to solve this problem. According to the principle of moments, the sum of the clockwise moments is equal to the sum of the counterclockwise moments.

The clockwise moments are due to the weight of the three boys on the right and can be calculated as follows

30 kg × 1 m = 30 kg m

30 kg × 2.5 m = 75 kg m

30 kg × 4 m = 120 kg m

The counterclockwise moment is due to the weight of the child on the left and can be calculated as follows

m × 5 m = 5m kg m

Since the system is in equilibrium, the sum of the clockwise moments must be equal to the counterclockwise moment. Therefore, we have

30 kg m + 75 kg m + 120 kg m = 5m kg m

Simplifying this equation, we get

225 kg m = 5m kg m

Dividing both sides by 5 kg m, we get

A young ice skater with mass of 40.0 kg has fallen and is sliding on the frictionless ice of a skating rink with a speed of 18.0 m/s then

the magnitude of her linear momentum = 720 kg m/s.

Kinetic Energy = 12,960 J.

Net Constant Horizontal Force for bringing her to rest in 6.00 s = -120 N

A: The magnitude of the skater's linear momentum can be calculated using the formula:

       P = m×v

where P is momentum, m is mass, and v is velocity. Plugging in the values given in the problem, we get:

      P = 40.0 kg × 18.0 m/s = 720 kg m/s

Therefore, the magnitude of her linear momentum, when she has this speed, is 720 kg m/s.

B: The skater's kinetic energy can be calculated using the formula:

     K = (1/2) × m ×[tex]v^2[/tex]

where K is kinetic energy, m is mass, and v is velocity. Plugging in the values given in the problem, we get:

     K = (1/2) × 40.0 kg × [tex](18.0 m/s)^2[/tex] = 12,960 J

Therefore, her kinetic energy is 12,960 J.

C: To bring the skater to rest in 6.00 s, a constant net horizontal force must be applied in the direction opposite to her motion. The magnitude of this force can be calculated using the formula:

     F = m×a

where F is force, m is mass, and a is acceleration. The skater's initial velocity is 18.0 m/s, and she comes to rest after 6.00 s, so her average acceleration during this time is:

      a = (0 m/s - 18.0 m/s) / 6.00 s = -3.00 [tex]m/s^2[/tex]

The negative sign indicates that the acceleration is in the opposite direction to her initial motion. Plugging in the values given in the problem, we get:

      F = 40.0 kg × (-3.00[tex]m/s^2[/tex]) = -120 N

Therefore, a constant net horizontal force of 120 N must be applied to the skater to bring her to rest in 6.00 s.

The magnetic force experienced by wire y is directed downwards.

Current in wire x creates a magnetic field that points downwards, according to the right-hand rule for the direction of magnetic fields around current-carrying wires.

The current in wire y, which is directed out of the page, interacts with this magnetic field and experiences a force that is perpendicular to both the current and the magnetic field.

Since the current in wire y is in the opposite direction to the magnetic field, the force on wire y is directed downwards.

Hence, when two parallel wires carry equal currents in opposite directions, they create magnetic fields that interact with each other to produce a force on each wire. The direction of this force can be determined using the right-hand rule, and in the case of wire y in this scenario, the force is directed downwards.

where P1 is the normal atmospheric pressure (1 atm), T1 is the normal boiling point temperature (373 K or 100 °C), P2 is the lower pressure at the top of Mount Everest (0.54 atm),

We can rearrange the equation and solve for T2:

T2 = ΔHvap/R * (ln(P1/P2)[tex])^-1[/tex] + T1

From the given information, we know that ΔHvap for water is -40.7 kJ/mol (note that this value is negative because energy is required to break the intermolecular bonds in liquid water to form water vapor), and R is 8.314 J/mol*K. Substituting these values, we get:

T2 = -(-40700 J/mol) / (8.314 J/mol*K) * ln(1/0.54) + 373 K

T2 = 270 K

The boiling point refers to the temperature at which a substance undergoes a phase change from liquid to gas. At the boiling point, the vapor pressure of the substance equals the atmospheric pressure. The boiling point is a physical property that varies depending on the substance and its surroundings.

For example, water boils at 100°C (212°F) at standard atmospheric pressure, but at higher altitudes where the atmospheric pressure is lower, the boiling point of water decreases. Conversely, at higher pressures, such as in a pressure cooker, the boiling point of water increases. The boiling point is also affected by the intermolecular forces between the particles of the substance. A substance with stronger intermolecular forces will have a higher boiling point compared to a substance with weaker intermolecular forces.

The standard enthalpy change for this reaction is -9.77 kJ/mol.

The van't Hoff equation relates the equilibrium constant (K) of a reaction to the standard enthalpy change (Δ_r H^∘) of the reaction with temperature (T) as follows:

ln(K2/K1) = (-Δ_r H^∘/R)[1/T2 - 1/T1]

where K1 and K2 are the equilibrium constants at temperatures T1 and T2, respectively, and R is the gas constant.

In this case, we are given that KP (which is the equilibrium constant for a gas-phase reaction at constant pressure) doubles when the temperature is increased from 300 K to 400 K. Therefore, we can write:

K2/K1 = 2

Taking the natural logarithm of both sides gives:

ln(2) = (-Δ_r H^∘/R)[1/400 K - 1/300 K]

Solving for Δ_r H^∘ gives:

Δ_r H^∘ = -R ln(2) / [1/400 K - 1/300 K]

Plugging in the value for the gas constant (R = 8.314 J/mol K), we get:

When an object is projected with a speed equal to the escape speed from the surface of the Earth, it will have just enough kinetic energy to overcome the gravitational potential energy and escape the gravitational field of the Earth. The formulas below provide the escape speed from Earth's surface.

[tex]v_{escape} = \sqrt{(2GM/R)}[/tex]

where M is the Earth's mass, R is its radius, and G is the gravitational constant.

If the particle is projected with a speed equal to 2.2 times the escape speed, its initial kinetic energy will be:

[tex]K_i = (1/2)mv^2 = (1/2)m(2.2v_{escape})^2 = 2.42K_{escape}[/tex]

where m is the mass of the particle and K_escape is the kinetic energy required to escape the gravitational field of the Earth.

When the particle is very far from the Earth, the gravitational potential energy is negligible compared to the kinetic energy, so the total energy of the particle will be conserved. As a result, we can compare the initial and end kinetic energies:

To find the eigenvalues and eigenvectors of the Hamiltonian, we solve the characteristic equation:

det(H - λI) = 0

where I is the 2x2 identity matrix and λ is the eigenvalue.

H - λI =

[E - λ, 1]

[1, -E - λ]

det(H - λI) = (E - λ)(-E - λ) - 1 = λ² - E² - 1

Setting this equal to zero and solving for λ, we get:

λ = ±sqrt(E² + 1)

To find the eigenvectors, we substitute the eigenvalues back into the matrix (H - λI)x = 0 and solve for x:

For λ = sqrt(E²+ 1), we get:

(E - λ)x1 + x2 = 0

x1 + (-E - λ)x2 = 0

Solving for x1 and x2, we get:

x1 = [1/sqrt(2(E² + 1))] * [sqrt(E² + 1), E]

x2 = [1/sqrt(2(E² + 1))] * [-E, sqrt(E² + 1)]

Similarly, for λ = -sqrt(E² + 1), we get:

(E - λ)x1 + x2 = 0

x1 + (-E - λ)x2 = 0

Solving for x1 and x2, we get:

x1 = [1/sqrt(2(E² + 1))] * [-sqrt(E² + 1), E]

x2 = [1/sqrt(2(E² + 1))] * [-E, -sqrt(E² + 1)]

The matrix H representing H with respect to the basis {|1>, |2>} is:

H =

[E, 1]

[1, -E]

Therefore, the eigenvalues of the Hamiltonian are λ = ±sqrt(E² + 1) and the corresponding eigenvectors are:

x1 = [1/sqrt(2(E² + 1))] * [sqrt(E² + 1), E],

x2 = [1/sqrt(2(E² + 1))] * [-E, sqrt(E² + 1)] for λ = sqrt(E² + 1),

x1 = [1/sqrt(2(E² + 1))] * [-sqrt(E² + 1), E] and

x2 = [1/sqrt(2(E² + 1))] * [-E, -sqrt(E² + 1)] for λ = -sqrt(E² + 1)

Note that the eigenvectors are normalized such that |x1|² + |x2|² = 1.

In Hal's electromagnet, the purpose of the electric current is to produce a magnetic field. A magnetic field is produced around a steel rod when an electric current passes through the wire encircling the rod. The interaction between the moving electric charges (electrons) in the wire and the steel rod produces the magnetic field.

The steel rod becomes magnetised by the magnetic field created by the electric current in the wire, converting it into an electromagnet. The amount of electric current passing through the wire determines how strong the magnetic field is. The magnetic field becomes more intense as current increases.

The electromagnet may interact with other magnetic fields and other magnetic objects using this magnetic field to draw or repel them. It serves as the foundation for many electromagnet applications, such as electric motors, generators, transformers, and magnetic storage units.

As a result, the purpose of the electric current in Hal's electromagnet is to produce a magnetic field that charges the steel rod, transforming it into an electromagnet that can pull or attract other magnetic objects.

If Earth were 2.5 times farther from the Sun, the intensity of sunlight at the Earth's surface would be 16% of its current value.

The Inverse Square Law states that the intensity of sunlight (or any form of radiation) is inversely proportional to the square of the distance from the source. Mathematically, this can be written as:

Intensity ∝ 1 / (Distance)²

Now, let's apply this to your question. If Earth were 2.5 times farther from the Sun:

1. Calculate the new intensity factor: (1 / (2.5)²) = 1 / 6.25
2. Find the percentage of current sunlight intensity: (1/6.25) * 100 = 16%

So, if Earth were 2.5 times farther from the Sun, the intensity of sunlight at the Earth's surface would be 16% of its current value.

The change in internal energy when a system is heated with 35 j of energy while it does 15 j of work is +50 J. The correct option is a).

The change in internal energy of a system can be calculated using the first law of thermodynamics, which states that the change in internal energy (ΔU) of a system is equal to the heat (q) added to the system minus the work (w) done by the system:

ΔU = q - w

In this case, the system is heated with 35 J of energy while it does 15 J of work. Therefore:

q = 35 J

w = -15 J (negative because work is being done by the system)

Plugging these values into the equation above, we get:

ΔU = 35 J - (-15 J) = 35 J + 15 J = 50 J

Therefore, the change in internal energy (ΔU) is +50 J. Answer is option a. +50 J.
