what is atomic weight​

The light from the green glow stick held by the Olympic sprinter will appear redshifted.

The phenomenon of redshift occurs when the source of light is moving away from the observer. In this case, as the sprinter is running towards you, the distance between you and the glow stick is decreasing over time. This decrease in distance causes a Doppler shift in the frequency of the light emitted by the glow stick.

Since the light is redshifted, its wavelength increases and the frequency decreases compared to its original emitted frequency. As a result, the light that reaches your eyes appears more towards the red end of the visible spectrum.

It is important to note that the color of the glow stick itself remains the same, but due to the relative motion between the source (the sprinter) and the observer (you), the light undergoes a change in frequency and appears redshifted.

This phenomenon is similar to the redshift observed in cosmology, where the light from distant galaxies appears to be redshifted due to the expansion of the universe.

Explanation:

I did the same thing I got a hundred on it

In this situation, the weight and the earth are the system, as they are the two objects that interact with each other.

The weight is falling due to the force of gravity exerted by the earth, and as it falls, it is also spinning a generator, which converts the kinetic energy of the weight into electrical energy that powers the light bulb. The earth, in turn, exerts an equal and opposite gravitational force on the weight, in accordance with Newton's third law. The energy transformation that takes place in this system involves the conversion of potential energy (due to the weight's position above the earth) into kinetic energy (as the weight falls) and then into electrical energy (as the generator is spun).

People on the ride "Spindletop" remain pinned against the wall when the floor drops. The minimum coefficient of static friction needed to prevent sliding down depends on the weight of the passenger.

a) In the situation described, a person is pinned against the inner wall of the vertical cylinder. Therefore, the forces acting on the person are the normal force (perpendicular to the wall), the force of gravity (downward), and the static friction force (tangential to the wall).

b) The minimum coefficient of static friction required to keep the person from sliding down to the new position on the floor can be calculated using the equation:

coefficient of static friction = tan(θ), where θ is the angle between the wall and the vertical.
At the new position of the floor, this angle can be found using trigonometry: θ = tan⁻¹(0.5/2.5) = 11.31 degrees.

Therefore, the minimum coefficient of static friction required is tan(11.31) = 0.202.

c) The coefficient of static friction does not depend on the mass of the passenger, as it is a property of the materials in contact (in this case, the passenger's clothing and the wall of the cylinder) and the angle between them. Therefore, the minimum coefficient of static friction required to prevent the passenger from sliding downward will be the same regardless of the passenger's mass.

Explanation:

The minimum gap between the automobiles is 16.9 feet, according to the supplied statement, in order to prevent a collision.

The size or extent of the displacement between two points is referred to as distance. Keep in mind that perhaps the difference between two and indeed the distance travelled between them are not the same. The length of the entire journey taken to go from one point to another is the distance travelled.

Explanation:

Plastics with a density less than or equal to 1.025 g/mL will float in seawater, while plastics with a density greater than 1.025 g/mL will sink.

Here are some examples of plastic densities:

Polyethylene terephthalate (PET) has a density of approximately 1.38 g/mL, so it will sink in seawater.

Polypropylene (PP) has a density of approximately 0.9 g/mL, so it will float in seawater.

High-density polyethylene (HDPE) has a density of approximately 0.95 g/mL, so it will float in seawater.

Polystyrene (PS) has a density of approximately 1.05 g/mL, so it will sink in seawater.

Based on the above examples, we can see that plastics such as polypropylene and high-density polyethylene will definitely float in seawater, while others such as polyethylene terephthalate and polystyrene will definitely sink. Other types of plastics with densities close to 1.025 g/mL may float or sink depending on their exact density and the conditions of the water, such as temperature and salinity.

The angular momentum of the system (ball and bar) is conserved about the hook because neither the hook nor gravity exerts any torque on this system about the hook.

The rotating inertia of an object or system of objects when they are moving about an axis that may or may not pass through them is described by a property known as angular momentum. The daily rotation of the Earth's axis and its yearly orbital revolution around the Sun give the planet its spin angular momentum. Since angular momentum is a vector quantity, both its magnitude and direction must be determined in order to fully represent it. The angular momentum of an orbiting object is proportional to its linear momentum, which is determined by dividing the mass (m) by the linear velocity (v) and by the perpendicular separation (r) from the axis of rotation.

False. Hydrostatic pressure force does not always act on the centroid of the area.

The statement that hydrostatic pressure force always acts on the centroid of the area is false. Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it. It depends on the depth and density of the fluid and is perpendicular to any surface it acts upon.

When considering a submerged surface, such as a submerged plate or wall, the hydrostatic pressure force is indeed applied normal to the surface. However, this force does not necessarily act at the centroid of the area. The distribution of hydrostatic pressure forces depends on the shape and orientation of the surface.

For irregularly shaped surfaces or surfaces with varying depths, the hydrostatic pressure force acts differently at different points. It follows the principle of Pascal's law, which states that the pressure at a point in a fluid is transmitted equally in all directions. As a result, the force distribution can vary across the surface.

In summary, the hydrostatic pressure force does not always act on the centroid of the area. Its distribution depends on the shape, orientation, and depth of the submerged surface, following the principles of Pascal's law.

Explanation:

We are given that

\(q_1=-5nC=-5\times 10^{-9} C\)

Where \(1nC=10^{-9} C\)

\(q_2=-2.00nC=-2\times 10^{-9}C\)

Distance between q1 and q2=0.40 m

We have to find the equilibrium  for a positive charge placed between them.

Let q be the positive charge placed at distance x from q1 .

r1=x

r2=0.40-x

At equilibrium

Total force =0

\(\frac{kq\times 5\times 10^{-9}}{x^2}-\frac{kq\times 2\times 10^{-9}}{(0.40-x)^2}=0\)

Where electric force=\(\frac{kq_1q_2}{r^2}\)

\(\frac{5\times 10^{-9}\times kq}{x^2}=\frac{2\times 10^{-9}\times kq}{(0.40-x)^2}\)

\(5(0.40-x)^2=2x^2\)

\(0.8-4x+5x^2=2x^2\)

\(5x^2-2x^2-4x+0.8=0\)

\(3x^2-4x+0.8=0\)

\(x=\frac{4\pm\sqrt{16-4\times 3\times 0.8}}{3(2)}\)

By using the formula

\(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)

\(x=\frac{4\pm 2.5298}{6}\)

By solving we get

\(x=1.0883,0.245\)

\(x=1.0883>0.40 \)

An interior designer is choosing a paint color for a room and has two samples that are both blue, however one blue is described as brighter than the other. Both would have the same wavelength but would differ due to the amplitude property of light.

It is the amplitude of light which makes one sample brighter than other.

The amplitude plays an important part in differentiating the same colors of the same wavelength. It tells us about the brightness or intensity of a certain light wave as compared to others of the same wavelength. So, whenever two same colors look different due to brightness, it is due to the amplitude property of the light.

La fórmula: P = W/t  ó  W = P x t. donde:

P = potencia

W = trabajo

Otra fórmula de potencia es: P= I x V

Proceso de carga de un capacitor - condensador

Una fórmula muy importante que también hay que tener en cuenta es: V = q/C que indica que el voltaje es proporcional a la carga que hay en un condensador.

De la fórmula de potencia P= I x V y considerando que la corriente es constante (corriente continua), entonces la potencia es proporcional al voltaje.  Si el voltaje aumenta en forma lineal, la potencia aumentará igual. Ver el siguiente diagrama.

Como la potencia varía en función del tiempo, no se puede aplicar la fórmula W = P x t, para calcular la energía transferida. Pero observando el gráfico, se ve que esta energía se puede determinar midiendo el área bajo la curva de la figura.

Energía Almacenada en un Condensador - Capacitor

El área bajo la curva es igual a la mitad de la potencia en el momento “t”, multiplicada por “t”.

Entonces: W = (P x t) / 2. Pero se sabe que P = V x I. Si se reemplaza esta última fórmula en la anterior se obtiene: W = (V x I x t) / 2, y como I x t = CV = Q, entonces para saber cuanta energía (W) hay en un condensador usamos una de las siguientes fórmulas:

W = (CV2/2) julios

W = (QV/2) julios

W  = (Q2/2C) julios

, donde:

W = Trabajo (Energía) en julios

C = Capacidad en faradios

V = voltaje en voltios en los extremos del condensador

Q = carga del condensador

Answer with the given explanations below: First the given formula that looks like this is: or where:

P = power

W = work

t = time

Next with another given power formula that looks like this is:

This is the charging process of a capacitor - capacitor #1.

Then it's a very important given formula that it must also be taken into account is: which it was indicated that the voltage is proportional to the charge on a capacitor.

In the following below, from the given power formula that looks like this is: and we are considering that the current is the constant (direct current), and then the power is proportional to the voltage. If the voltage increases linearly, the power will increase the same. See the following diagram. (I'm sorry, Yhungbabe, I don't have the diagram to show you in order to refer to the total energy stored in the capacitor because I havenèt learned the energy stored in the capacitor)

Anyway, since the power varies as a function of the time, the given formula that looks like this is: cannot be applied to calculate the energy transferred. But looking at the graph, it seems that this energy can also be determined by measuring the area under the curve of the figure.

This is The Energy Stored in a Capacitor - Capacitor #2.

The area under the curve is equal to the half of the power at time "t", being multiplied by "t".

Then with the given formula below that looks like this is:

But it's known that If this is the last given formula is being replaced in the previous one, we obtain the new given formula that looks like this is: and as another new given formula that looks like this is: there's so to find out how much energy (W) that there's in a capacitor that we use in one of the new given formulas that looks like in the listed below are:

The magnitude of the average force exerted on the glove by the other boxer is approximately 1844 N .

When a boxer delivers a punch, it imparts a linear impulse to the target.

The magnitude of the impulse is equal to the change in momentum of the target.

The duration of contact between the boxer's fist and the target determines the average force exerted on the target.

In this problem, the linear impulse delivered by the hit of a boxer is 236 N·s, and the contact time is 0.128 s.

To find the average force exerted on the glove by the other boxer, we can use the definition of impulse:

Impulse = Force x Time

Rearranging this formula, we get:

Force = Impulse / Time

Substituting the given values, we have:

Force = 236 N·s / 0.128 s = 1843.75 N

Therefore, the magnitude of the average force exerted on the glove by the other boxer is approximately 1844 N.

It is important to note that this calculation assumes that the contact force is constant during the entire duration of contact, which may not be the case in reality.

In addition, the force experienced by the target may vary depending on the angle and location of the punch.

The speed of the projectile when it strikes the ground below is approximately 620.6 m/s.

We can use the kinematic equations of motion to solve this problem.

First, we can find the time it takes for the projectile to hit the ground using the vertical motion equation:

y = vi*t + (1/2)at²

where y is the vertical displacement (in this case, the initial height of the cliff), vi is the initial vertical velocity (in this case, zero), a is the acceleration due to gravity (-9.8 m/s^2), and t is time.

Plugging in the values, we get:

265 m = 0t + (1/2)(-9.8 m/s²)*t²

Solving for t, we get:

t = √((2*265 m) / (9.8 m/s²)) = 8.25 s

Next, we can find the horizontal displacement of the projectile using the horizontal motion equation:

x = v*t

where x is the horizontal displacement, v is the initial horizontal velocity, and t is time.

Since the initial velocity is at a 45-degree angle, we can break it down into its horizontal and vertical components:

v_initial_x = v_initial*cos(45 degrees) = 350 m/s * cos(45 degrees) = 247.5 m/s

v_initial_y = v_initial*sin(45 degrees) = 350 m/s * sin(45 degrees) = 247.5 m/s

The horizontal displacement can now be calculated as:

x = v_initial_x * t = 247.5 m/s * 8.25 s = 2041.9 m

Finally, we can find the speed of the projectile when it hits the ground using the total velocity equation:

v_final² = v_initial_x² + v_initial_y² + 2ay

where v_final is the final velocity, v_initial_x and v_initial_y are the horizontal and vertical components of the initial velocity, and y is the vertical displacement.

Plugging in the values, we get:

v_final² = (247.5 m/s)² + (350 m/s)² + 2*(-9.8 m/s²)*(265 m)

Solving for v_final, we get:

v_final = √((247.5 m/s)² + (350 m/s)² + 2*(-9.8 m/s²)*(265 m)) = 620.6 m/s

Therefore, the speed of the projectile when it strikes the ground below is approximately 620.6 m/s.
