The first positive side of technological development is the ease of receiving information, both locally and internationally. Unlike in the past, in this modern era, we don't have to bother buying newspapers.

2. Easy to communicate

With the messaging application that can send messages, both voice messages and text messages as well as telephone, which will then make it easier to communicate. Unlike the past, communication still has to be through letters and you have to send it to the post office. This letter cannot directly reach the recipient of the letter. It also requires quite expensive costs and takes a long time.

3. More Practical Shopping

In the past we had to go to the market or other shopping places and it took a long time. It's different from now, you can simply order various needs just by using an online shopping application. Then pay for it and wait for the order to arrive at home without the hassle of leaving the house.

4. Learning becomes easier

In the past we had to buy thick books and cost a lot. Right now you only need to buy ebooks, although not a few are paid, but there are many e-books that you can get for free. Besides being able to read books easily, the rapid development of technology will then facilitate the teaching and learning process. Especially during a pandemic like this.

A truck accelerating at 0.0083 meters/second2 covers a distance of 5.8 ×\(10^4\) meters. If the truck's mass is 7,000 kilograms, the work done to reach this distance is 3.3× \(10^6\) joules.

The correct answer is option E.

To calculate the work done by the truck to cover a distance of 5.8 × \(10^4\)meters, we need to use the equation for work:

Work = Force × Distance

In this case, the force can be calculated using Newton's second law:

Force = mass × acceleration

Where:

Acceleration (a) = \(0.0083 meters/second^2\)

Distance (d) = 5.8 ×\(10^4\) meters

Mass (m) = 7,000 kilograms

First, let's calculate the force exerted by the truck:

Force = mass × acceleration = (7,000 kg) ×\((0.0083 meters/second^2)\)= 57.1 Newtons

Next, we can calculate the work done:

Work = Force × Distance = (57.1 N) × (5.8 × 10^4 meters) = 3.3158 × \(10^6\)joules

Rounded to the nearest significant figure, the work done by the truck is approximately 3.3 × \(10^6\) joules.

Therefore, the correct answer is E.

Answer:

d = 0.015m

Explanation:

To find the thickness of the antireflective coating you take into account that waves must reflect and interfere destructively between them. A wave travels twice the thickness d of the coating, and for the destructive interference it is necessary that the reflected wave is (m+1/2) factor of the incident wave. Thus, you have:

\(2d=(m+\frac{1}{2})\lambda_n\)

d: thickness of the coating

m: order of the interference (m=1 for the minimum thickness)

λn: wavelength of light inside the coating

You first calculate the wavelength of the wave:

\(\lambda=\frac{c}{f}=\frac{3*10^8m/s}{10*10^9Hz}=0.03m\)

\(\lambda_{coating}=\lambda_n=\frac{n_{air}}{n_{coating}}\lambda_{air}\\\\\lambda_n=\frac{1}{1.50}(0.03m)=0.06m\)

Then, you replace the values of m and λn in order to calculate d:

\(d=\frac{1}{2}(m+\frac{1}{2})\lambda_n\)

\(d=\frac{1}{2}(0+\frac{1}{2})(0.06m)=0.015m=1.5cm\)

hence, the thickness of the antireflective coating must be 0.015m

.How far objects are clearly visible by the eyes is known as the far point. The point where objects appear clearly without strain is known as the near point. In the question, the near point is 20 cm from the eye and the far point is at infinity, which means it can see up to infinity distance. Hence, the range of Anna's vision is 1.

To calculate the power of the eye lens, we use the following formula:

The refractive power of the eye = 1/f

where f is the focal length of the eye lens.2. Far point of the eye, the image is formed at the retina, therefore,

f = 20 mm = 0.02 m  = 1/f = 1/0.02 m = 50 D3.

Near the point, the image is formed at a distance of 20 cm from the eye lens.

To calculate the focal length:

f = 20 cm = 0.2 mf = 1/f = 1/0.2 m = 5 D4.

Range of Anna's vision = Refractive power of eye at the near point - Refractive power of eye at the far point

= 5 D - 50 D= -45

Thus, the range of Anna's vision is -45 D.

Answer:

0.1962N.

Explanation:

Weight is a force, so we use newtons second law which states F=ma. So the weight of a watermelon on earth is 2kg x 9.81m/s², which is 19.62N (newtons). On the moon it weighs 2 x 1.63 which is 3.26N.

The weight of the pen is 0.02 x 9.81, which is 0.1962N. If the pen is not to fall the frictional force needs to be equal to this force,

so the answer is 0.1962N.

False. Norton's Theorem states that any two-terminal source can be reduced to an equivalent current source in parallel with an equivalent resistance, not an equivalent shunt resistance, simplifying complex electrical networks.

Norton's Theorem states that any two-terminal source can be reduced to an equivalent current source in parallel with an equivalent resistance, not an equivalent shunt resistance. This theorem is a fundamental concept in electrical circuit analysis and provides a powerful tool for simplifying complex networks.

When applying Norton's Theorem, the original two-terminal network is replaced by a Norton current source (IN) connected in parallel with a Norton resistance (RN). The Norton current source represents the current that would flow through a short circuit connected across the terminals of the original network, while the Norton resistance represents the resistance seen by the short circuit.

The equivalent resistance is determined by removing all independent sources (voltage or current sources) from the original network and calculating the resistance across the terminals. The equivalent current source is then calculated by short-circuiting the terminals and determining the current flowing through the short circuit.

By utilizing the Norton equivalent circuit, complex networks can be simplified, allowing for easier analysis using standard circuit techniques. It is important to note that the equivalent resistance is in parallel, not shunt, with the Norton current source.

The statement that the nitrogen geysers of Triton carry carbon grit into the winds of its atmosphere is false.

Triton is a moon of the planet Neptune, and it is known for its unique geological features, including nitrogen geysers. These geysers are believed to erupt from beneath the surface, expelling nitrogen gas and dust particles into space. However, there is no evidence or scientific consensus to suggest that these geysers carry carbon grit into the winds of Triton's atmosphere.

Carbon grit refers to small particles of carbonaceous material, such as soot or dust. While carbon compounds have been detected on Triton's surface, primarily in the form of organic molecules, there is no specific information or observations indicating the presence of carbon grit being transported by nitrogen geysers or carried into Triton's atmosphere.

The understanding of Triton's atmosphere and geology is based on limited direct observations, as the Voyager 2 spacecraft provided the most detailed data during its flyby in 1989. Further investigations and future missions may provide additional insights into the composition and dynamics of Triton's atmosphere and the role of geysers in its overall processes.

With the "twist-out" style, knots can be opened and released to create wavy and fuller loose curls.

The twist-out style is a popular hairstyling technique commonly used to create wavy or curly hair textures. It involves twisting sections of hair together and allowing them to set before unraveling the twists. The resulting hairstyle is characterized by defined and elongated curls or waves.

To achieve a twist-out, the hair is typically divided into small sections, and each section is twisted from the roots to the ends. The twists are then secured, and the hair is left to dry or set for a certain period.

Once the twists are released, the hair will have a wavy or curly pattern, depending on the size of the twists and the hair's natural texture.

By using the twist-out method, knots are opened and released, allowing the hair to spring back into its natural or manipulated curl pattern.

Therefore, this technique gives the hair more volume, texture, and movement, resulting in wavy and fuller loose curls.

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.

The student should have controlled the power of the mains supply, as this affects the amount of energy transferred to the heating element and the rate at which it increases in temperature.

A heating element is a device that produces heat by converting electrical energy into heat energy. It is commonly found in electric heaters, stoves, ovens, toasters, and other appliances. The heating element works by passing an electric current through a coil of wire or metal, typically made of nickel-chromium or iron-chromium alloy. When the current passes through the coil, it produces heat as a result of resistance to the flow of current. The heat is then transferred through the surrounding material and into the air. Heating elements are usually designed to operate at a certain temperature, and when this temperature is reached, the element turns off automatically. Heating elements are important components of many household appliances and are used to provide a safe and efficient source of heat.
