If the charge on one object was doubled and the charge on the other object was tripled then the electrostatic force of attraction between the two charged object will increased by a factor of 6.

The electrostatic force of attraction F between two bodies of charges Q and q is given by the relation,

F = KQq/r²

r is the distance between them.

Now, letter say that the charge on one object was doubled and the charge on the other object was tripled, so, we can write,

Q' = 3Q and q = 2q,

Now, the new force of attraction,

F' = K(3Q)(2q)/r²

Putting F = KQq/r²,

F' = 6F

So, the new force of attraction between the two bodies will be increased by 6 times.

The factors affecting tensile strength in steel plates are manganese content and thickness of the plate. The higher the manganese content and thickness, the higher the tensile strength.

Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking or losing strength. In an experiment to determine the factors affecting tensile strength in steel plates, two factors were measured: the manganese content and the thickness of the plate.The results showed that the tensile strength increased with higher levels of manganese content and thickness. This means that the higher the manganese content and thickness of the plate, the higher the tensile strength. It is important to note that these two factors are not the only ones that affect tensile strength, but they are significant factors that should be considered when designing and manufacturing steel plates.

A Wheatstone bridge is a resistance bridge that has variable resistances that are adjusted so there is equal current flow through the legs of the bridge and zero potential across the bridge.

This configuration is widely used in scientific and engineering applications to precisely measure unknown electrical resistance values. The Wheatstone bridge consists of four resistors connected in a diamond shape, with a galvanometer connected between two opposite corners to detect any potential difference.

When the bridge is balanced, the ratio of the known resistances is equal to the ratio of the unknown resistances, allowing for accurate determination of the unknown resistance value. The Wheatstone bridge has been a fundamental tool in electrical measurements since its invention in the 19th century and continues to be utilized in modern electronics and instrumentation.

the magnitude of the flux through the surface produced by the magnetic field B⃗ is approximately 0.00893 Wb.

To calculate the magnitude of the flux through the surface produced by the magnetic field B⃗, we can use the formula:

|Φb| = ∫∫ B⃗ · dA⃗

Given that the surface is a flat, square surface in the xy-plane at z=0, we can represent the surface area vector dA⃗ as pointing in the positive z-direction.

dA⃗ = dxdy(0i^+0j^+1k^) = k^ dxdy

Since the surface is a square with side length 4.20 cm, we can set up the integral as follows:

|Φb| = ∫∫ B⃗ · k^ dxdy

Integrating over the surface, we have:

|Φb| = ∫(from 0 to 4.20 cm) ∫(from 0 to 4.20 cm) Bz dxdy

Plugging in the values of Bz = -0.475 T, we get:

|Φb| = ∫(from 0 to 4.20 cm) ∫(from 0 to 4.20 cm) (-0.475 T) dxdy

Evaluating the integral, we find:

|Φb| = (-0.475 T) * (4.20 cm) * (4.20 cm)

Converting the units to webers (Wb), we use the conversion factor 1 T·m² = 1 Wb, and convert the square centimeters to square meters:

|Φb| = (-0.475 T) * (4.20 cm) * (4.20 cm) * (1 m² / 10,000 cm²)

Simplifying the calculation, we find:

|Φb| ≈ 0.00893 Wb

Therefore, the magnitude of the flux through the surface produced by the magnetic field B⃗ is approximately 0.00893 Wb.

The resistance of a conductor rise with temperature because high temperature cause vibration which make difficult the flow of electron.

When electrons move through a conductor, it collide with atoms, electrons or other substances. These collisions cause resistance which leads to generate heat. Heating the metal conductor leads to more vibration of an atoms which in turn makes it more difficult for the electrons to flow through a conductor that leads to increasing resistance.

So we can conclude that the resistance of a conductor rise with temperature because high temperature cause vibration which make difficult the flow of electron.

So 3840 divided by 64 is 60.

By deducting the higher frequency (70 Hz) from the lower frequency (66 Hz), the beat frequency, which is 4 Hz, can be computed.

When two notes with slightly different frequencies are sounded together, they create a beat frequency, which is the difference between the two frequencies. In this case, the beat frequency can be calculated by subtracting the lower frequency (66 Hz) from the higher frequency (70 Hz), which results in a beat frequency of 4 Hz.

This means that the two notes are interfering with each other, creating four beats per second.

These beats are audible and can be heard as a pulsating sound, which is the beat frequency. The speed of the beats depends on the difference between the two frequencies, and the closer the frequencies are, the slower the beats will be. This phenomenon is used in tuning musical instruments to achieve perfect harmony and eliminate dissonance.

Explanation:

The work done by the applied force on the block against the frictional force is 15.75 J.

Work done is equal to product of force applied and distance moved.

Work = Force x Distance

Given is a 4 kg block is pushed 2m at an acceleration of 0.2 meter per second square up a vertical wall by constant force f applied at an angle of 37 degree with the horizontal if the coefficient of kinetic friction, μ between the block and the wall is 0.30.

From the equilibrium of forces acting on the block, we have

F - f = ma

where, F is applied force, f is frictional force, m is the mass and a is the acceleration.

Frictional force f =  μmgsinθ

Substitute the values, we get

Fcos(37) - μmgsin(37) = ma

Fcos(37) - (0.3)(4)(9.8)sin(37) = 4(0.2)

0.799F - 7.077 = 0.8

F = 9.86 N

Work done by the applied force is

W = Fdcosθ

W = 9.86 x 2 x cos(37)

W = 15.75 J

Thus, the work done by the applied force on the block against the frictional force is 15.75 J.

Answer:

The height balls rise above the collision point, is approximately 7.37 meters

Explanation:

The given parameters just before the collision are;

The mass, m₁ and velocity, v₁ of the ball moving upward are;

m₁ = 3.0 kg, v₁ = 22 m/s

The mass, m₂ and velocity, v₂ of the ball moving downward are;

m₂ = 1.3 kg, v₂ = -11 m/s (downward motion)

The type of collision = Inelastic collision

We note that the momentum is conserved for inelastic collision

Let, \(v_f\), represent the final velocity of the balls after collision, we have;

∴ Total initial momentum = Total final momentum

m₁·v₁ + m₂·v₂ = (m₁ + m₂)·\(v_f\)

Therefore, we get;

m₁·v₁ + m₂·v₂ = 3.0 kg × 22 m/s + 1.3 kg × (-11) m/s = 51.7 kg·m/s

(m₁ + m₂)·\(v_f\) = (3.0 kg + 1.3 kg) ×

∴ 51.7 kg·m/s = 4.3 kg × \(v_f\)

\(v_f\) = (51.7 kg·m/s)/4.3 kg ≈ 12.023 m/s

The final velocity, \(v_f\) ≈ 12.023 m/s

The maximum height, h, the combined balls will rise from the point of collision, moving upward at a velocity of \(v_f\) ≈ 12.023 m/s, is given from the kinetic equation of motion, v² = u² - 2·g·h, as found follows

At maximum height, we have;

\(h_{max} = \dfrac{v_f^2}{2 \cdot g }\)

Therefore;

\(h_{max} \approx \dfrac{12.023^2}{2 \times 9.81 } \approx 7.37\)

The height the combined two balls of putty rise above the collision point, \(h_{max}\) ≈ 7.37 m.

Observations in our solar system support the conclusion that collisions between portions of material in the solar system cancel their up-and-down motions, leaving them revolving in a thin disk around the Sun. Observations do not support the conclusion that objects in the far outer solar system orbited so slowly that they would have experienced few collisions, leaving behind small, solid bodies.

The Nebular Condensation Theory proposes that our solar system is formed from a rotating disk of gas and dust called the solar nebula. According to this theory, collisions between portions of material in the solar system canceled their up-and-down motions, resulting in a thin disk of material revolving around the Sun. Observations of our solar system, such as the flattened shape of the planetary orbits and the presence of a protoplanetary disk around young stars, support this conclusion.

Additionally, observations suggest that large collisions can change the rotation directions of planets. This is evident in the case of Uranus, which has an extreme axial tilt likely caused by a past collision. Other examples of planets with tilted axes or unusual rotation patterns also support this conclusion.

However, observations do not support the conclusion that objects in the far outer solar system orbited slowly enough to experience few collisions, resulting in small, solid bodies. Instead, the outer solar system is known to contain a significant population of icy objects, such as dwarf planets and comets, which have likely experienced numerous collisions throughout their history. These collisions have shaped their orbits, compositions, and sizes.

Overall, while some conclusions of the Nebular Condensation Theory plus collisions are supported by observations in our solar system, others do not find substantial evidence in favor.

The de Broglie wavelength (λ) associated with a charged particle having charge 'q' and mass 'm', when it is accelerated by a potential V, can be expressed as:

λ = h / √(2 * m * q * V)

where 'h' is Planck's constant.

The de Broglie wavelength is a key concept in quantum mechanics, as it relates the momentum of a particle to its wavelength. This wavelength is essential in understanding the wave-particle duality of matter, which is the idea that particles can exhibit both wave-like and particle-like behavior. In the case of a charged particle accelerated by a potential V, its de Broglie wavelength can be determined using the expression above.

This equation is derived from the de Broglie hypothesis, which states that every particle with momentum (p) has a corresponding wavelength given by λ = h / p. For a charged particle accelerated by a potential V, its kinetic energy (K) can be expressed as K = q * V. The relationship between kinetic energy and momentum is given by K = (p^2) / (2 * m). By substituting the expression for kinetic energy into the momentum equation and solving for the wavelength, we obtain the formula for the de Broglie wavelength of the charged particle under the influence of the potential V.
