Answer:

12.7 m

Explanation:

The following data were obtained from the question:

Initial velocity (u) = 56.7 Km/hr

Maximum height (h) =..?

First, we shall convert 56.7 Km/hr to m/s. This can be obtained as follow:

Initial velocity (m/s) = 56.7 x 1000/3600

Initial velocity (m/s) = 15.75 m/s

Next, we shall determine the time taken to get to the maximum height. This can be obtained as follow:

Initial velocity (u) = 15.75 m/s

Final velocity (v) = 0 m/s

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) =?

v = u – gt (since the ball is going against gravity)

0 = 15.75 – 9.8 × t

Rearrange

9.8 × t = 15.75

Divide both side by 9.8

t = 15.75/9.8

t = 1.61 secs.

Finally, we shall determine the maximum height as follow

h = ½gt²

Acceleration due to gravity (g) = 9.8 m/s²

Time (t) = 1.61 secs.

Height (h) =..?

h = ½gt²

h = ½ × 9.8 × 1.61²

h = 4.9 x 1.61²

h = 12.7 m

Therefore, the maximum height reached by the ball is 12.7 m

Colors seen on some TV screens result from color additive mixing, which involves combining the primary colors of red, green, and blue (RGB) in varying intensities to produce a full range of colors.

By adjusting the amount of each primary color that is displayed, different hues and shades can be created. This process is also known as the RGB color model.

Each pixel on the TV screen is made up of three subpixels, one for each primary color, which are illuminated to create the desired color.

This allows for the creation of millions of colors using only three primary colors.

Other color models, such as the CMYK model used in printing, use subtractive mixing to achieve the desired color.

Explanation:

I HOPE it will help you

Answer:

force of gravity

Explanation:

When a permanent magnet is placed on top of a straight wire, a magnetic field is produced in the region surrounding the wire due to the motion of charges in the wire. The magnetic field produced by the wire interacts with the magnetic field of the permanent magnet and causes a force to be exerted on the wire.

The direction of the force is perpendicular to both the magnetic field and the current in the wire. If the wire is not fixed in place, it will experience a force and move in a direction that is perpendicular to both the magnetic field and the current in the wire. This phenomenon is known as the Lorentz force, which is the force that is exerted on a charged particle when it moves in an electromagnetic field.

The direction of the force is given by the right-hand rule, which states that if the thumb of the right hand points in the direction of the current, and the fingers point in the direction of the magnetic field, then the palm of the hand will point in the direction of the force. The magnitude of the force is proportional to the current in the wire and the strength of the magnetic field.

Therefore, the stronger the magnetic field or the current, the greater the force that is exerted on the wire. The Lorentz force is the basis for the operation of many devices such as motors, generators, and transformers.

Explanation:

In a parallel circuit, each lamp is connected to the power source independently, meaning that the lamps are not directly connected to each other. Therefore, if one lamp filament breaks in this setup, the other three lamps will continue to work unaffected.

When the filament of one lamp breaks, it essentially opens the circuit for that particular lamp. However, the remaining lamps are still connected in parallel, so the current can flow through them independently. The other lamps will continue to receive electricity from the power source and light up normally.

This behavior is a characteristic of parallel circuits, where each component has its own individual connection to the power source. If the lamps were connected in series, the situation would be different. In a series circuit, a break in one lamp's filament would interrupt the flow of current throughout the entire circuit, and all the lamps would go out.

To find the acceleration of the jet aircraft during takeoff, we can use Newton's second law of motion, which states that the net force acting on an object is equal to its mass times its acceleration:

F_net = m * a

where F_net is the net force, m is the mass, and a is the acceleration.

In this problem, the thrust force of the engine is the net force acting on the aircraft during takeoff. Therefore, we can write:

F_net = 59,500 N

m = 4,550 kg

Substituting these values into the equation above, we get:

59,500 N = 4,550 kg * a

Solving for a, we get:

a = 59,500 N / 4,550 kg

a ≈ 13.08 m/s^2

Therefore, the magnitude of the jet's acceleration during takeoff is 13.08 m/s^2.

There are two types of directional antennas: Yagi-Uda antenna and parabolic antenna.

1. Yagi-Uda antenna: This type of directional antenna consists of multiple elements arranged in a linear fashion. It has a driven element, which is connected to the transmitter or receiver, and several passive elements. The passive elements include a reflector and one or more directors.

The reflector is placed behind the driven element, while the directors are positioned in front of it. The Yagi-Uda antenna is known for its gain, which is the ability to focus the signal in a particular direction. By properly designing the lengths and positions of the elements, the antenna can achieve a high gain in the desired direction.

2. Parabolic antenna: This type of directional antenna uses a parabolic reflector to focus the incoming or outgoing signals. The reflector is a curved surface, usually shaped like a dish, with a central feed antenna located at the focal point.

The parabolic shape helps in concentrating the signals towards the feed antenna, resulting in a highly focused beam. This type of antenna is commonly used for satellite communication and long-range point-to-point links.

When changing the amplitude and frequency of a longitudinal wave and a transverse wave, there is a relationship between the two that becomes apparent. Specifically, as the amplitude of a longitudinal wave increases, the frequency remains constant, and the wave becomes more compressed or rarefied.

In contrast, as the amplitude of a transverse wave increases, the frequency also increases, and the wave becomes more tightly packed or "wiggly". Despite these differences, both types of waves share some similarities in terms of their behavior. For example, both longitudinal and transverse waves can be characterized by their wavelength, amplitude, and frequency. Additionally, both types of waves can be reflected, refracted, and diffracted.

Explanation:

[H⁺] [OH⁻] = 10⁻¹⁴

(1×10⁻⁶) [OH⁻] = 10⁻¹⁴

[OH⁻] = 1×10⁻⁸

The concentration of hydroxyl ion will be  \(10^{-8}\)M.

Bonjour à toi,

An electrically neutral object does not mean that it has no electrical charge. If today we find some elementary particles without electric charge (Higgs Boson, photon and gluon), the neutrality of the atom and molecules, or more globally of matter is due to various processes. An atom is electrically neutral because the electric charges that compose it compensate each other (as much negative charge, the electron, as positive, the proton). Ionic molecules arrange themselves so that the electric charges that compose them compensate each other.

This is the density function of I when C and D are independent. It describes the distribution of intensities at a given point, given the distribution of light power from the source and the distance from the source to the point.

To find the density function of I, we need to determine the probability density function (PDF) of the random variable I.

Given that C and D are independent, we can use the concept of change of variables to find the density function of I.

First, we know that I = C/D^2. We can rearrange this equation to express D in terms of I: D = (C/I)^(1/2).

Now, we can find the derivative of D with respect to I to obtain the Jacobian of the transformation: dD/dI = -(1/2)*(C/I)^(3/2).

Since C is uniformly distributed in the interval (1,2), its density function fC(c) is constant within that range and zero outside. Thus, fC(c) = 1 for 1 ≤ c ≤ 2, and fC(c) = 0 otherwise.

Using the formula for change of variables, the density function of I, fI(i), can be obtained as follows:

fI(i) = fC(C/I)(dD/dI)

= 1 * (-(1/2)(C/I)^(3/2))

= -(1/2)*(C/I)^(3/2)

where C is restricted to the range (1,2) and D is calculated as D = (C/I)^(1/2).

The statement that rules of thumb are known as a non-traditional approach to setting standards is false. Rules of thumb are actually a traditional and informal method of making rough estimations or decisions.

Contrary to the statement, rules of thumb are not considered a non-traditional approach to setting standards. In fact, they have been used for centuries as a traditional and informal way to make rough estimations or decisions. Rules of thumb are practical guidelines or principles that are based on experience or common sense rather than precise measurements or formal procedures.

These rules are often used in various fields, such as engineering, construction, finance, and everyday life. They serve as quick and convenient methods to make approximate calculations or judgments when precise data or detailed analysis may not be available or necessary. For example, the "rule of thumb" that suggests spending around 30% of your income on housing expenses is a commonly used guideline in personal finance.

While rules of thumb can be helpful in certain situations, it's important to recognize their limitations. They are not meant to replace rigorous analysis or professional judgment. Depending solely on rules of thumb can lead to inaccuracies or oversimplifications. Therefore, they should be used with caution and in conjunction with more precise methods when necessary.
