The type of wave interference that results in lesser wave amplitude is called "destructive interference".

Destructive interference occurs when two waves with the same frequency and amplitude are out of phase with each other, meaning that the crest of one wave coincides with the trough of the other wave.

As a result, the positive and negative displacements of the waves cancel each other out, leading to a reduction in the overall amplitude of the resulting wave.

Destructive interference can occur in various types of waves, including sound waves, water waves, and electromagnetic waves such as light.

It is an important concept in wave physics, and is used in many applications such as noise-cancelling headphones, where destructive interference is used to cancel out unwanted sound waves.

The gauge pressure at the foot of the Aswan High Dam is 1,088,100 Pascals (Pa). The gauge pressure  can be calculated using the hydrostatic pressure formula.

Hydrostatic pressure is the pressure exerted by a fluid at rest due to the force of gravity. It can be calculated using the formula P = ρgh, where P represents the pressure, ρ is the density of the fluid, g is the acceleration due to gravity, and h is the depth or height of the fluid column.

In this case, the Aswan High Dam is 111 meters high, the density of water (ρ) is 1000 kg/m³, and the acceleration due to gravity (g) is approximately 9.81 m/s². By plugging these values into the formula, we get:

P = (1000 kg/m³) × (9.81 m/s²) × (111 m)

P = 1,088,100 Pa

Thus, the gauge pressure at the foot of the Aswan High Dam is 1,088,100 Pascals (Pa). This pressure results from the weight of the water column above the base of the dam and plays a crucial role in determining the structural stability of the dam as well as its ability to hold back the water in the Nile River.

Explanation:

To find the resultant velocity of the duck flying south against a northerly wind, we need to consider both the duck's velocity and the wind's velocity. Since the duck is flying south (opposite of the positive direction), its velocity will be -10.0 m/s. The northerly wind has a velocity of 2.5 m/s (positive direction).

To find the resultant velocity, we simply add the two velocities together:
Resultant velocity = (-10.0 m/s) + (2.5 m/s) = -7.5 m/s

The negative sign indicates that the duck's resultant velocity is in the southward direction, and the magnitude of this velocity is 7.5 m/s. So, the duck is flying south with a resultant velocity of 7.5 m/s against the northerly wind.

White dwarf supernovae are more useful for measuring cosmic distances than massive star supernovae because they are more consistent in their peak brightness.

Since massive stars have different luminosities, it is difficult to measure their distance. On the other hand, white dwarf supernovae have almost the same luminosity, which makes it easier to measure their distance. This is because white dwarf supernovae are created when a white dwarf star reaches a certain mass, and the process of reaching this mass is consistent and predictable.

This means that when a white dwarf supernova is observed, scientists can be more sure that its luminosity is consistent with other white dwarf supernovae. This makes them more reliable for measuring distance.

Answer: 1120673.9 volts

Explanation:

The de Broglie wavelength of an electron is given by the equation λ = h / (mv), where h is the Planck constant, m is the mass of the electron, and v is its velocity.

The kinetic energy of an electron can be calculated from the potential difference it is accelerated through, using the equation KE = qV, where q is the charge of the electron and V is the potential difference.

Setting these two equations equal to each other, we get λ = h / (mv) = h / √(2mKE).

Solving for V, we get V = KE / q = (h^2 / 2mq) / λ^2.

Substituting the given values, we get V = (6.626 x 10^-34 J.s)^2 / (2 x 9.109 x 10^-31 kg x 1.602 x 10^-19 C x (0.27 x 10^-9 m)^2)

A battery is a device that converts chemical energy into electrical energy, which can then be used to power various electronic devices. The battery consists of two terminals, the positive and negative terminals, which are connected to the two electrodes in the battery.

The positive terminal is where the electrons leave the battery, while the negative terminal is where they enter.

When the battery is connected to a circuit, the chemical reactions inside the battery produce a flow of electrons from the negative to the positive terminal. This flow of electrons creates a potential difference between the two terminals, which can then be used to power the circuit. Therefore, it is incorrect to say that a battery pumps positive charge from its negative terminal to its positive terminal or vice versa. Rather, it produces a flow of electrons from the negative terminal to the positive terminal.

This means that if you double the mass of the block attached to a spring-block oscillator, the frequency of the oscillation will decrease by a factor of √2, which is approximately 1.4. In other words, the oscillation will become slower and have a longer period. This relationship can be understood by considering that increasing the mass will increase the inertia of the system, making it harder for the spring to push and pull the mass back and forth at the same rate.

In an elastic collision, both momentum and kinetic energy are conserved.

Let's define the positive direction to be to the right.

Before the collision, the momentum of the system is

Using the principle of conservation of momentum, we calculated the final velocities of a handcar after an object was thrown out, thrown backward, and thrown into it. The final velocities were 5.32 m/s to the east, 3.97 m/s to the west, and 4.12 m/s to the west, respectively.

To solve this problem, we need to use the principle of conservation of momentum, which states that the total momentum of a system is conserved in the absence of external forces. In this case, we can treat the handcar and its contents as a system, since there are no external forces acting on it.

Let's first calculate the initial momentum of the system. The momentum is given by the product of the mass and velocity, so the initial momentum is:

[tex]p_{initial} = m_{total} \times v_{initial[/tex]

where m_total = 170 kg is the total mass of the system and [tex]v_{initial[/tex] = 5.50 m/s is the initial velocity of the car.

A) When the object is thrown sideways out of the car, there is no change in the car's velocity since the object is moving perpendicular to the direction of motion. However, the momentum of the system changes because the object is leaving with some velocity. Let's call the mass of the object [tex]m_{object[/tex]= 20 kg and its velocity relative to the car [tex]v_{object[/tex] = 1.90 m/s. The momentum of the object is:

[tex]p_{object} = m_{object} \times v_{object[/tex]

The total momentum of the system after the object is thrown out is:

[tex]p_{final} = p_{initial} - p_{object}[/tex]

since the momentum of the object is leaving in the opposite direction of the initial velocity of the car, the final velocity of the car will be slightly smaller than the initial velocity, and its direction will be unchanged. Using the conservation of momentum equation, we can solve for the final velocity of the car:

[tex]p_{final} = m_{total} * v_{final[/tex]

[tex]v_{final} = p_{final} / m_{total}[/tex]

Substituting the values we have:

[tex]$v_{final} = \frac{m_{total} \cdot v_{initial} - m_{object} \cdot v_{object}}{m_{total}} = \frac{170 \text{ kg} \cdot 5.50 \text{ m/s} - 20.0 \text{ kg} \cdot 1.90 \text{ m/s}}{170 \text{ kg}} = 5.32 \text{ m/s}$[/tex]

Therefore, the final velocity of the car is 5.32 m/s to the east.

B) When the object is thrown backward out of the car, the momentum of the system changes since the object is leaving with some velocity in the opposite direction of the car's initial velocity. Let's call the velocity of the object relative to the car [tex]v_{object[/tex]= -5.50 m/s. The momentum of the object is:

[tex]p_{object} = m_{object} \times v_{object[/tex]

The total momentum of the system after the object is thrown out is:

[tex]p_{final} = p_{initial} - p_{object[/tex]

since the momentum of the object is leaving in the opposite direction of the initial velocity of the car, the final velocity of the car will be smaller and in the opposite direction. Using the conservation of momentum equation, we can solve for the final velocity of the car:

[tex]p_{final} = m_{total} \times v_{final[/tex]

[tex]v_{final} = p_{final} / m_{total[/tex]

Substituting the values we have:

[tex]v_{final} = \frac{m_{total} \cdot v_{initial} - m_{object} \cdot v_{object}}{m_{total}} = \frac{170 \text{ kg} \cdot 5.50 \text{ m/s} - 20.0 \text{ kg} \cdot (-5.50 \text{ m/s})}{170 \text{ kg}} = 3.97 \text{ m/s}$[/tex]

Therefore, the final velocity of the car is 3.97 m/s to the west.

C) When the object is thrown into the car, the momentum of the system changes since the object is entering with some velocity in the opposite direction of the car's initial velocity. Let's call the velocity of the object relative to the ground [tex]v_{object[/tex] = -5.90 m/s. The momentum of the object is:

[tex]p_{object} = m_{object} \times v_{object[/tex]

The total momentum of the system after the object is thrown in is:

[tex]p_{final} = p_{initial} + p_{object[/tex]

since the momentum of the object is entering in the opposite direction of the initial velocity of the car, the final velocity of the car will be smaller and in the opposite direction. Using the conservation of momentum equation, we can solve for the final velocity of the car:

[tex]p_{final} = m_{total} * v_{final[/tex]

[tex]v_{final} = p_{final} / m_{total[/tex]

Substituting the values we have:

[tex]$v_{final} = \frac{m_{total} \cdot v_{initial} + m_{object} \cdot v_{object}}{m_{total}}$[/tex]

[tex]\frac{(170\,kg \cdot 5.50\,m/s + 20.0\,kg \cdot -5.90\,m/s)}{170\,kg}[/tex]

= 4.12 m/s

Therefore, the final velocity of the car is 4.12 m/s to the west.

Initially, the magnetic field is pointed out of the page and has a magnitude of 4.5 t, but it is decreasing at a rate of 8.5 g/s. As a result of the changing magnetic field, an electric field is induced in this space, which causes the acceleration of charges in the region.

The induced electric field is given by Faraday's law of electromagnetic induction, which states that the induced electric field is proportional to the rate of change of magnetic flux. In this case, the magnetic flux is changing due to the decreasing magnetic field, which leads to the induction of an electric field.

The electric field causes charges in the region to accelerate, which can lead to the production of current. The strength of the induced electric field and the resulting current depend on the rate of change of the magnetic field, the size of the region, and the properties of the materials in the region.

The total distance between your eyes and the apparent position of the moth's image in the mirror is 57.7 cm. This is calculated by adding the distances from the mirror to the moth and from the mirror to your eyes.

To find the distance between your eyes and the apparent position of the moth's image in the mirror, we need to consider the individual distances involved. The moth is 11.1 cm in front of the mirror. Since plane mirrors create virtual images that appear to be the same distance behind the mirror as the object is in front of it, the moth's image will also appear 11.1 cm behind the mirror.

You are 46.6 cm behind the moth, so you are also 46.6 cm away from the mirror. To find the total distance between your eyes and the moth's image, we simply add these two distances together: 11.1 cm + 46.6 cm = 57.7 cm.
