Answer:  The reason why some objects feel warmer than others even if they are at the same temperature has to do with their thermal conductivity. Thermal conductivity is a measure of how well a material can transfer heat. Materials with high thermal conductivity transfer heat easily, while materials with low thermal conductivity do not transfer heat as easily.

When you touch an object, your skin can’t actually detect the temperature of the object itself. Instead, it senses its own temperature. If you touch an object that is a good thermal conductor, it will transfer heat to or from your skin quickly, making your skin feel warmer or colder. On the other hand, if you touch an object that is not a good thermal conductor, it will transfer heat to or from your skin more slowly, so your skin won’t feel as warm or cold.

So, even if two objects are at the same temperature, one may feel warmer than the other because it is transferring heat to your skin more quickly due to its higher thermal conductivity.

2 × 10 5 kg subway train is brought to a stop from a speed of 0.500 m/s in 0.8 m by a large spring bumper at the end of its track. The spring constant of the spring bumper is 2.5 × 10^5 N/m.

The potential energy stored in the spring when compressed is given by the equation

U = 1/2 kx^2,

where k is the spring constant and x is the compression distance.

When the subway train is brought to a stop, the kinetic energy of the train is transformed into potential energy stored in the spring.

Therefore, the potential energy stored in the spring is equal to the initial kinetic energy of the train.

The initial kinetic energy of the train is given by the equation

K = 1/2 mv^2,

where m is the mass of the train and v is the initial velocity.

Substituting the given values, we get K = 250 J.

When the spring is compressed by 0.8 m, it stores this potential energy. Thus, we can write 250 J = 1/2 k (0.8 m)^2.

Solving for k, we get k = 2.5 × 10^5 N/m.

Behavior of electron occupying a 3d orbital is complex and is influenced by many factors, including energy level, shape of the orbital, and interactions with other electrons and the nucleus.

The behavior of an electron occupying a 3d orbital is related to its energy level and the shape of the orbital. In general, a 3d orbital has more complex shape than a 2p or 3s orbital, which can lead to different electron behavior.

In an atom, the electron occupying a 3d orbital experiences a potential energy due to the attraction between the negatively charged electron and the positively charged nucleus. The potential energy is related to the distance between the electron and the nucleus, as well as the electron's charge and the nuclear charge.

The electron's energy level in a 3d orbital is related to the number of electrons and their arrangement in the atom. For example, in a transition metal atom, the electrons in the 3d orbital may have a higher energy level due to the presence of additional electrons in the outer energy levels.

The behavior of the electron in a 3d orbital can also be affected by the presence of other electrons in nearby orbitals. For example, if there are other electrons occupying the 4s orbital, they may shield the 3d electron from some of the nuclear charge, which could affect its energy level.

Answer:

π/10 rads

Explanation:

It takes an hour (60 minutes) for the minute's hand to turn a full circle or achieve an angular rotation of

2πl rad.

Now, number of periods of 3 minutes in an hour is;

Number of periods = 60/3 = 20 periods

Thus, 3 minutes rotation accounts for 1/20 of 2π the rotation of the minute's hand in an hour.

Thus;

Angular displacement = (1/20) * 2π = π/10 rads

Answer:

43.3 m/s.

Explanation:

Assuming the potential energy is due to the gravitational potential energy, we can use the conservation of energy to find the kinetic energy:

Total energy = Potential energy + Kinetic energy

Kinetic energy = Total energy - Potential energy

Kinetic energy = 300 J - 40 J = 260 J

However, we need to know the mass of the object to convert the kinetic energy to velocity. We can use the potential energy to find the mass:

Potential energy = mgh

40 J = m(9.81 m/s^2)(300 m)

m = 0.137 kg

Now we can use the kinetic energy to find the velocity:

Kinetic energy = (1/2)mv^2

260 J = (1/2)(0.137 kg)v^2

v^2 = (2*260 J) / 0.137 kg

v = 43.3 m/s (rounded to one decimal place)

Therefore, the kinetic energy is 260 J and the velocity of the object when it reaches the ground is 43.3 m/s.

The angles from the central maximum where the next four maxima in the two-slit interference pattern occur, in terms of d and λ are \(arcsin((1λ) / d), arcsin((2λ) / d), arcsin((3λ) / d), and, arcsin((4λ) / d)\)

To find the angles θ for the next four maxima in the two-slit interference pattern, we can use the equation for constructive interference, which is:

\(mλ = d * sin(θ)\)

Here, m is the order of the maximum, λ is the wavelength of the light, d is the slit separation, and θ is the angle from the central maximum.

Since d = 3a, we can use this equation to find the angles for the next four maxima (m = 1, 2, 3, 4).

The color that gets deflected the most by a diffraction grating is blue, while the color that gets deflected the least is red.

When light passes through a diffraction grating, it undergoes interference and diffraction, resulting in the separation of colors. The amount of deflection or bending of light depends on the wavelength of the light. Shorter wavelengths (blues and violets) are deflected more than longer wavelengths (reds and oranges).

The reason for this lies in the fundamental principles of diffraction. Diffraction occurs when light encounters an obstacle or a periodic structure with features comparable to the wavelength of light. In a diffraction grating, these features are the regularly repeated small slits or grooves. When light passes through these slits, it diffracts into multiple beams, each corresponding to a different wavelength.

According to the equation for diffraction by a grating, the angle at which the different colors are diffracted depends on the wavelength of the light and the spacing between the slits. The equation, known as the grating equation, is given by:

nλ = d * sin(θ),

where n represents the order of diffraction, λ is the wavelength of light, d is the spacing between the slits, and θ is the angle of diffraction.

Since the equation involves the sine of the angle of diffraction, smaller wavelengths (such as blue and violet) will have larger angles of diffraction compared to longer wavelengths (such as red and orange). This means that blue and violet light will be deflected more than red and orange light.

Answer:

W = 221.872 N

Explanation:

The weight of a box, F = 362 N

It makes an angle of 37.8 degrees with the horizontal.

We need to find the gravitational force acting down the inclined plane. The component of weight that is acting down the inclined plane is mgsinθ.

W = mgsinθ

= 362× sin(37.8)

= 221.87 N

So, the required component of gravitational force is 221.87 N.

a) The magnitude of the vector sum of a+b+c is approximately 4.47 meters, with a direction of 43.9 degrees east of north.

b) The magnitude of the vector difference of a-b is approximately 5.83 meters, with a direction of 49.6 degrees north of west.

a) To find the vector sum of a+b+c, we first add the x-components and the y-components separately. The x-component is calculated as (4 cos 37°) + (-3 cos 53°) + (2 cos 180°) = 2.67 meters, and the y-component is calculated as (4 sin 37°) + (-3 sin 53°) + (2 sin 90°) = 2.8 meters. Then, using the Pythagorean theorem, we find the magnitude of the vector sum: sqrt(\((2.67)^2\) + \((2.8)^2\)) ≈ 4.47 meters. The direction can be determined using the inverse tangent function: \(tan^(-1)(2.8/2.67)\) ≈ 43.9 degrees. Thus, the vector sum of a+b+c has a magnitude of approximately 4.47 meters and a direction of 43.9 degrees east of north.

b) To find the vector difference of a-b, we subtract the x-components and the y-components separately. The x-component is calculated as (4 cos 37°) - (-3 cos 53°) + (2 cos 180°) = 7.41 meters, and the y-component is calculated as (4 sin 37°) - (-3 sin 53°) + (2 sin 90°) = -0.83 meters. Then, using the Pythagorean theorem, we find the magnitude of the vector difference: sqrt(\((7.41)^2\)+ \((-0.83)^2\)) ≈ 5.83 meters. The direction can be determined using the inverse tangent function:\(tan^(-1)(-0.83/7.41)\) ≈ -49.6 degrees. Note that the negative sign indicates a direction opposite to the positive x-axis, so the vector difference of a-b has a magnitude of approximately 5.83 meters and a direction of 49.6 degrees north of west.

The wavelengths of the spectral lines in the Lyman series of the hydrogen spectrum can be calculated using the Rydberg formula:

1/λ = \(R * (1/n1^2 - 1/n2^2)\)

Where λ is the wavelength of the spectral line, R is the Rydberg constant (approximately \(1.097 * 10^7 m^-^1)\), and n1 and n2 are positive integers representing the energy levels of the electron in the hydrogen atom.

For the Lyman series, we have m = 1, which means the electron transitions from higher energy levels (n2) to the first energy level (n1 = 1).

Let's calculate the wavelengths for the first four members of the Lyman series:

For n2 = 2:

1/λ = \(R * (1/1^2 - 1/2^2)\)

1/λ = \(R * (1 - 1/4)\)

1/λ = \(R * (3/4)\)

λ = \(4/3R\)

Substituting the value of the Rydberg constant:

λ = \((4/3) * (1.097 × 10^7 m^-^1)\)

λ ≈ \(1.464 * 10^7 m\)

For n2 = 3:

1/λ = \(R * (1/1^2 - 1/3^2)\)

1/λ = \(R * (1 - 1/9)\)

1/λ = \(R * (8/9)\)

λ = \(9/8R\)

Substituting the value of the Rydberg constant:

λ = \((9/8) * (1.097 * 10^7 m^-1)\)

λ ≈ \(1.231 * 10^7 m\)

For n2 = 4:

1/λ = \(R * (1/1^2 - 1/4^2)\)

1/λ = \(R * (1 - 1/16)\)

1/λ = \(R * (15/16)\)

λ = \(16/15R\)

Substituting the value of the Rydberg constant:

λ = \((16/15) * (1.097 * 10^7 m^-^1)\)

λ ≈ \(1.164 * 10^7 m\)

For n2 = 5:

1/λ = \(R * (1/1^2 - 1/5^2)\)

1/λ = \(R * (1 - 1/25)\)

1/λ = \(R * (24/25)\)

λ = \(25/24R\)

Substituting the value of the Rydberg constant:

λ = \((25/24) * (1.097 * 10^7 m^-^1)\)

λ ≈ \(1.097 * 10^7 m\)

Therefore, the wavelengths of the first four members of the Lyman series are approximately:

\(1.464 * 10^7 m,\)

\(1.231 * 10^7 m,\)

\(1.164 * 10^7 m,\)
