As electrons are constantly ejected from the metal, it becomes increasingly positive in charge. The magnitude of positive charge eventually becomes large enough to attract the ejected electrons.

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are known as photoelectrons. It is important to note that the emission of photoelectrons and the kinetic energy of the ejected photoelectrons are affected by the frequency of the incident light on the metal's surface. Photoemission is the process by which photoelectrons are ejected from the surface of a metal due to the action of light.

Electrons on the metal's surface absorb energy from incident light and use it to overcome the attractive forces that bind them to the metallic nuclei, resulting in the photoelectric effect.

Two stars are of equal luminosity. Star A is 3 times as far from you as star B. Star A appears the same brightness as star B.

Luminosity is a measure of the total amount of energy a star emits in a given amount of time. Apparent brightness, on the other hand, is the amount of light that reaches us from a star and is influenced by the star's distance from us, as well as its luminosity.

When two stars have the same luminosity, their apparent brightness will be determined by their distance from us. If star Y is four times dimmer looking than star X on relatively unobscured sightlines, it means that star Y must be farther away from us. This is because the amount of light we receive from a star decreases with increasing distance.

Luminosity: The total amount of energy a star emits.

Apparent brightness: The amount of light that reaches us from a star.

The acceleration of the elevator is [tex]2.19 m/s^2[/tex], calculated using Newton's second law and the forces on the hanging mass.

The acceleration of the elevator can be determined by analyzing the forces acting on the hanging mass. When the elevator is in motion, the hanging mass is subjected to two forces: its weight (mg), which always points downward, and the tension force in the spring scale, which is equal in magnitude but opposite in direction to the weight (since the mass is not accelerating vertically).

Using Newton's second law of motion (F=ma), we can set up the following equation:

T - mg = ma

where T is the tension force in the spring scale, m is the mass of the hanging mass (10.0 kg), and a is the acceleration of the elevator (which we want to find).

Substituting the given values, we get:

120 N - (10.0 kg)[tex](9.81 m/s^2)[/tex] = (10.0 kg) a

Simplifying and solving for a, we get:

a = (120 N - 98.1 N) / (10.0 kg) =[tex]2.19 m/s^2[/tex]

Therefore, the acceleration of the elevator is [tex]2.19 m/s^2[/tex].

Move perfect mirror to the right by 86.2 nm to produce minimum power at detector and minimum power is 0.225 mW.

To create an interferometer using a 50-50 beam splitter and two mirrors, we can split a laser beam into two paths using the beam splitter, bounce one path off a perfect mirror, and the other off a mirror that does not reflect all light.

In this setup, interference between the two paths of the laser light can produce a pattern of constructive and destructive interference, which can be detected at a detector.

If the detected power is initially at its maximum, we can move the perfect mirror to the right to produce a minimum power at the detector. This is because moving the mirror changes the path length difference between the two paths of the laser light, and this can change the interference pattern.

To determine how much we need to move the perfect mirror, we can use the fact that the detected power is maximum when the two paths of the laser light are in phase, and minimum when they are out of phase. When only the vertical arm is blocked, the power measured at the detector is 2.25 mw, and when only the horizontal arm is blocked, the power measured at the detector is 2.025 mw.

The power detected at the detector is given by:

P = [tex](1/2) * P_in * (1 +- cos(Δφ))[/tex]

where[tex]P_in[/tex] is the incident power, Δφ is the phase difference between the two paths of the laser light, and the ± sign depends on which path is blocked.

When the power is maximum, the phase difference is an integer multiple of 2π, i.e., Δφ = [tex]2\pi n[/tex]. When the power is minimum, the phase difference is an odd multiple of π, i.e., Δφ = [tex](2n+1)\pi /2.[/tex]

We can solve for the phase difference in terms of the incident power and the measured powers:

Δφ = [tex]arccos[(4P_min/P_in) - 1][/tex]

where [tex]P_min[/tex] is the minimum power detected at the detector, which is 2.025 mw.

Plugging in the values, we get:

Δφ = [tex]arccos[(4*2.025/9) - 1] = 2.18 radians[/tex]

To produce a minimum power at the detector, we need to change the phase difference to [tex](2n+1)\pi /2[/tex]. This means we need to move the perfect mirror by a distance Δx such that:

Δφ = [tex](2n+1)\pi /2 = 1.57, 4.71, 7.85, ...[/tex]

We can use the wavelength of the laser to determine the distance Δx:

Δx = Δφ * λ / [tex]2\pi[/tex]

lambda: wavelength of laser = 300 nm

Put values:

Δx = 86.2 nm

So we need to move the perfect mirror to the right by 86.2 nm to produce a minimum power at the detector, and the minimum power at the detector is 0.225 mW.

With the same continuous broadband masking noise, the 4000-Hz tone is probably harder to distinguish than the 1500-Hz tone.

Generally speaking, lower-frequency noises are more easily concealed or drowned out by ambient noise than higher-frequency ones. Lower-frequency sounds have longer wavelengths than higher-frequency ones, making them more susceptible to interference and phase cancellation from the noise.

Consequently, compared to the 1500-Hz tone, the 4000-Hz tone is perhaps more challenging to distinguish from the same continuous broadband masking noise. The 4000-Hz tone is more sensitive to being masked by background noise because of its higher frequency and shorter wavelength.

The blower uses 100 volts of the difference in potential when consumes current of 3 c/s in a time of 5.10min

The bulb is filled with a gas, typically a mixture of nitrogen and argon, that reduces the oxygen in the bulb to help stop the filament from burning. A filament with a high electric current resistance is made of a special wire, usually tungsten.

First, we should convert the power and the time:

Power of blower = 3.0 x 10² J/s

                         = 3.0 x 10² W

Time = 5.10 min

                         = 5.10 x 60 s

                                 = 306 s

Now, Charge = I × t

                        = 3 A × 306 s

                                      = 918 C

Finally, we can calculate the potential difference consumed:

                             ΔV = P × t / Q

                          ΔV = (3.0 x 10² W) × (306 s) / (918 C)

                               ΔV = 100 V

The correct answer is "kinetic energy decreases because iron shavings move in the direction of magnetic force."

When a horseshoe magnet is moved near a pile of iron shavings, the magnet's magnetic force attracts the shavings, causing them to move toward the magnet. As a result, the iron shavings begin to align along the magnet's magnetic field lines, attaching to both ends of the magnet.

Because the iron shavings are moving in the direction of the magnetic force, they are doing work against it, and this work is transferred from their kinetic energy to the system's magnetic energy. The system's kinetic energy is reduced as a result.

As a result, the correct answer is that kinetic energy decreases as iron shavings move in the direction of magnetic force.

The runner's speed is 1.91 m/s. The speed of a runner can be calculated by multiplying their step length (the distance covered by one step) by their stride frequency (the number of steps taken per unit time).  

We can calculate the runner's speed using the formula:

speed = step length x stride frequency

Plugging in the given values:

speed = 1.50 m/step x 76 steps/min

We first need to convert the units of stride frequency to strides/second:

76 steps/min x 1 min/60 s = 1.27 strides/s

Now, we can substitute this value into the formula:

speed = 1.50 m/step x 1.27 strides/s

Simplifying the expression:

speed = 1.91 m/s

Therefore, the runner's speed is 1.91 m/s.

Step length can be influenced by a number of factors, including a runner's height, leg length, and running form. Stride frequency, on the other hand, is largely determined by a runner's running speed. As a runner increases their speed, their stride frequency tends to increase as well. However, there is a limit to how fast a runner can move their legs, and at a certain point, increases in speed are achieved through increases in step length rather than stride frequency.

Measuring step length and stride frequency can be useful for runners who want to optimize their running form and efficiency. By increasing their step length or stride frequency, runners can increase their speed without necessarily increasing their energy expenditure. However, it's important to note that there is no "ideal" step length or stride frequency that works for everyone. Runners should experiment with different stride lengths and frequencies to find what feels most comfortable and efficient for them.

When the elevator comes to a stop, the supporting cable is held at -3000 N of tension.

A force that is transmitted when a rope, cable, or string is pulled tight is tension. The pulling force that an object exerts on a rope, cable, or string transmits along its length to another object that is attached to the other end is known as tension. The force along the length of a rope or cable that is being stretched or pulled is known as tension in physics.

We must determine the elevator's net force in order to determine the supporting cable's tension. The sum of the elevator's acceleration and mass creates this net force. As a result of the elevator's slowdown in this instance, its acceleration is negative (opposing its velocity).

The elevator's acceleration can be determined using the equation for average acceleration:

where a = (v_f - v_i) / t

The elevator's acceleration is denoted by a, the elevator's final velocity is denoted by v_f, and the initial velocity is denoted by v_i, which is 7.0 m/s. The time interval is denoted by t, which is 3.5 seconds.

a = (0 - 7.0) / 3.5

a = -2.0 m/s²

The net force on the elevator is given by the equation:

F_net = m × a

where:

F_net is the net force on the elevator

m is the mass of the elevator (1500 kg)

a is the acceleration of the elevator (-2.0 m/s²)

Substituting the values:

F_net = 1500 × -2.0

F_net = -3000 N

The linear velocity in miles per hour of the tip of the lawnmower blade spinning at 2500 revolutions per minute in a lawnmower that cuts a path 22 inches wide is approximately 2.724 miles per hour.

To determine the linear velocity in miles per hour of the tip of the lawnmower blade, we need to use the following formula:

v = ωr

Where:

v is the linear velocity of the tip of the lawnmower blade in miles per hour

ω is the angular velocity of the lawnmower blade in radians per minute

r is the radius of the lawnmower blade.

We know that the lawnmower blade is spinning at 2500 revolutions per minute. To convert revolutions per minute to radians per minute, we need to multiply by 2π. So, the angular velocity of the lawnmower blade is: ω = 2500 rpm * 2π/60 = 261.66 rad/min

The lawnmower blade's radius is half the width of the path it cuts. Since the path is 22 inches wide, the radius is: r = 22 inches / 2 = 11 inches. To convert inches to miles, we need to divide by 63,360 (the number of inches in a mile). So, the radius in miles is:

r = 11 inches / 63,360 inches/mile = 0.0001736 miles

Now, we can use the formula to find the linear velocity:

v = ωr = 261.66 rad/min * 0.0001736 miles = 0.0454 miles/min

To convert miles per minute to miles per hour, we need to multiply by 60. So, the linear velocity in miles per hour is:

The energy loss to thermal energy is 1500.51 J

This is defined as the attribute of any rotating object that is supplied by the moment of inertia multiplied by the angular velocity.

The conservation of angular momentum principle states that angular momentum remains constant until an external force is applied.

L = angular momentum (I*)

where I denotes the moment of inertia and w denotes the angular speed

Angular momentum previously: Lb = It*0

Angular momentum following: La = (It + Ic)*1

(It + Ic)*1 = It*0

1 = the angular velocity after

0 = 1*[It/(It + Ic)])

ω₁ = I₀ω₀ / I₁

I0 = The turntable's moment of inertia

A cylinder's moment of inertia Equals 12mr2.

I₀ = ½(34)(2.1) (2.1) = 74.97 kgm²

I₁ = I0 + I(clay) = 74.97 kgm2 + m(clay)*r(clay)2 = 74.97 kgm2 + (12)*(1.1)² = 89.49 kgm²

1 = I0/I1 = 74.97*7.7/89.49= 6.45rad/s

Energy conversion to thermal energy

Some energy is wasted when the clay deforms and clings to the turntable, therefore energy is not preserved. We can conclude:

E₁= ½I₁ω₁² = ½ × 89.49 × 6.45² = 3723.007

The pilot then flies over the terrain in a series of parallel lines, dropping food packets at regular intervals. Once the end of the terrain is reached, the pilot turns and flies back in the opposite direction, dropping packets at the same regular intervals. The distance between the parallel lines is determined by the size of the squares in the grid, and the regular intervals at which packets are dropped are determined by the desired coverage density. By flying in this pattern, the pilot can ensure that no areas of the terrain are missed, and that the food packets are distributed evenly throughout the entire area. This method is commonly used in agriculture and forestry applications, as well as in search and rescue operations.

The strength of the electric field formed by the charged rod at a distance of 80.0 cm on its central axis is 1.35 x 10^12 N/C.

The electric field created by a charged rod at a point on its central axis can be calculated using the formula,

[tex]E = \dfrac{k \lambda}{r}[/tex]

where k is Coulomb's constant (k = 9.0 x 10^9 N m^2/C^2), lambda is the linear charge density of the rod in C/m, and r is the distance from the rod to the point where the electric field is being measured, also in meters.

Substituting the given values,

[tex]E = \dfrac{9.0 \times 10^9 \times 120}{0.8}[/tex]

E = 1.35 x 10^12 N/C

Therefore, the strength of the electric field formed by the charged rod at a distance of 80.0 cm on its central axis is 1.35 x 10^12 N/C.

Net force is the vector sum of forces acting on a flyspeck or object. The net force is a single force that replaces the effect of the original forces on the flyspeck's stir. It gives the flyspeck the same acceleration as all those factual forces together as described by Newton's alternate law of stir.

It's possible to determine the necklace associated with the point of operation of a net force so that it maintains the movement of spurts of the object under the original system of forces.
