M= 8kg

F= 7N

Unknown:

Acceleration of a falling object

Formula:

a = F/m

Solution and Final Answer:

a = 7 kg.m/s² ÷ 8 kg

a = 0.88 m/s²

because the divisor and dividend there are the same units so cancel it(kg) then the rest is m/s² so it will be the unit of 0.88 will become 0.88 m/s²

A box camera is a simple type of camera, the most common form being a cardboard or plastic box with a lens in one end and film at the other. They were sold in large numbers during the late 19th and early 20th centuries. The lenses are often single element designs meniscus fixed focus lens, or in better quality box cameras a doublet lens with minimal (if any) possible adjustments to the aperture or shutter speeds. Because of the inability to adjust focus, the small lens aperture and the low sensitivity of the sensitive materials available, these cameras work best in brightly lit day-lit scenes when the subject is within the hyperfocal distance for the lens and of subjects that move little during the exposure. Eventually, box cameras with photographic flash, shutter and aperture adjustment were introduced, allowing indoor photos.

The average speed of the baton can be determined by dividing the total distance travelled by the total time taken for that travelling.

\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\)

First, we will find the total distance, by adding the distances travelled by both Mahiya and Mrinmoy, while carrying the baton.

\(Total\ Distance = Distance\ Travelled\ by\ Mahiya\ to\ pass\ the\ baton\ to\ Mrinmoy\ +\ Distance\ Travelled\ by\ Mrinmoy\ to\ pass\ the\ baton\ to\ Mahiya\ +\ Final\ Distance\ Travelled\ by\\ Mahiya\)Total Distance = 60 m + 120 m + 60 m = 240 m

Now, we will find the total time taken for this travelling. To find out the total time we will divide each distance travelled by the speed of the traveller during that distance:

\(Total\ Time = \frac{60\ m}{6\ m/s}+\frac{120\ m}{4\ m/s}+\frac{60\ m}{3\ m/s}\\\\Total\ Time = 10\ s\ +\ 30\ s\ +\ 20\ s\)

Total Time = 60 s

Now, we finally find the average speed of the baton by using the formula:

\(Average\ Time = \frac{Total\ Distance}{Total\ Time}\\\\Average\ Time = \frac{240\ m}{60\ s}\)

Average Speed = 4 ms⁻¹

ANSWER:

Charge flows together through the external circuit at a rate that is everywhere the same. The current is no greater at one location as it is at another location. The actual amount of current varies inversely with the amount of overall resistance. There is a clear relationship between the resistance of the individual resistors and the overall resistance of the collection of resistors. As far as the battery that is pumping the charge is concerned, the presence of two 6-Ω ;resistors in series would be equivalent to having one 12-Ω resistor in the circuit. The presence of three 6-Ω resistors in series would be equivalent to having one 18-Ω resistor in the circuit. And the presence of four 6-Ω resistors in series would be equivalent to having one 24-Ω resistor in the circuit.

EvidenceUsing the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.

(See the attach for the answer of this section0)

Conclusion:Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

Did your data support your hypothesis? Use evidence to explain.

Yes, my data supported my hypothesis. In my hypothesis I stated that if I project light through glass it will refract the most and after investigation, I discovered that the glass reflected the light the most bending it at a

Which material refracted the light rays the most: air, water, or glass?

The glass refracted the light the most, bending it to a

Which material refracted the light rays the least: air, water, or glass?

The air refracted the light the least because the light did not bend at all.

How does density affect refraction?

Density affects refraction because light waves, unlike sound waves, don’t need to interact with other particles to travel and they travel faster in the air and since light travels in a straight line, the denser the material gets the less it will be able travel in a straight line hence, it will refract more the denser the material gets.

Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.

Since diamonds are very dense material, I predict that the light will refract because light travels in a straight line and does not need to interact with other materials to travel, so the light will refract in the dense material.

Explain where you observe reflection, refraction, and absorption of light in your everyday activities

In my everyday life I observe reflection when I look in the mirror and brush my teeth, I observe refraction when I drink a glass of water with a straw, and I observe absorption when I wear dark colors outside and I get really hot because the dark colors are absorbing the sunlight.

1. Select Intro to begin.

2. Once the simulation loads, you will drag the protractor onto the screen so that the 0 lines up with the dotted line in the center of the screen.

3. You will test all three materials in the bottom, blue half of the screen: air, water, and glass.

4. Record your observations of how the light rays interact as they pass from air, on the top of the screen, through the three materials on the bottom of the screen

Data:

Record the data from each trial in the data chart below. Be sure to fill in the chart completely.

Material Interactions

List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen. Evidence

Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.

Trial One Air on top  The light does not reflect, nor does it refract. Angle:  180

Index of refraction:  1.00

Air on bottom  The light does not reflect, nor does it refract.

Trial Two Air on top  The light does not reflect, nor does it refract. Angle:  166

Index of refraction:  1.33

Water on bottom  The light reflects and it refracts.

Trial Three Air on top  The light does not reflect, nor does it refract. Angle:  152

Index of refraction:  1.50

Glass on bottom  The light reflects and it refracts.

Conclusion:

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

1. Did your data support your hypothesis? Use evidence to explain.

No, in my hypothesis I stated that water would refract or  bend the most, but I found that it was water it was glass that would refract or reflect the most.

2. Which material refracted the light rays the most: air, water, or glass

I have found that glass refracted the most.

3. Which material refracted the light rays the least: air, water, or glass?

I found that air refracted the least because there was no bend.

4. How does density affect refraction?

Density affects refractions because of light waves unlike sound waves. sound waves don’t need to interact with the other particles to travel faster in the air and since light always travels in a straight line the denser the material gets and the less it will travel in a straight line. Hence it would refract more the denser the material gets.

5. Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.

A diamond is a very dense material. So, I can predict that light would refract in the material because light travels in a straight line and does not need to interact with any objects or materials to travel so the light would refract in the dense material.

6. Explain where you observe reflection, refraction, and absorption of light in your everyday activities

In my everyday life I notice a reflection in the mirror or in a window. I also can observe a refraction when I drink a glass a water using a straw. I can also observe that while I’m cleaning the dishes how the water absorbed into the sponge.

Powering Your Home: Understanding Energy Resources in Dubai, United Arab Emirates

Dubai, one of the seven emirates of the United Arab Emirates, is a rapidly growing city with a population of over 3.3 million people. With the increase in population and development, the demand for electricity has also risen significantly. Have you ever wondered where the electricity that powers your home comes from? In this handout, we will provide you with information about the energy resources used to power the electrical grid in Dubai.

Nonrenewable Resources:

Dubai relies heavily on nonrenewable resources such as natural gas and oil to generate electricity. As per Dubai Electricity and Water Authority (DEWA), in 2020, 94% of the electricity generated in Dubai came from natural gas and 6% from coal.

Renewable Resources:

Dubai has been working to diversify its energy mix by investing in renewable resources. According to DEWA, 6% of Dubai's electricity in 2020 was generated from renewable sources, such as solar and waste-to-energy. DEWA has set a target to increase the share of renewable energy in Dubai's energy mix to 75% by 2050.

Nuclear Energy:

Dubai is also investing in nuclear energy to diversify its energy mix. The first nuclear power plant in the UAE, the Barakah Nuclear Energy Plant, started operations in 2020. It is expected to generate 5.6 GW of electricity and will contribute to reducing carbon emissions.

Most Used Renewable Resource:

Dubai has the world's largest single-site solar energy project, the Mohammed bin Rashid Al Maktoum Solar Park. It is a key component of Dubai's clean energy strategy, and its capacity is expected to reach 5 GW by 2030. The solar park uses photovoltaic solar panels to convert sunlight into electricity.

Interesting Fact:

Dubai is home to the world's tallest building, the Burj Khalifa, which has been designed to be energy-efficient. It uses a combination of technologies such as a high-performance glass facade, an efficient air-conditioning system, and a double-decker elevator system that reduces energy consumption by 20%.

Conclusion:

Dubai's energy mix is currently dominated by nonrenewable resources, with natural gas being the primary source of electricity generation. However, the city is making significant strides to increase the share of renewable energy and diversify its energy mix. By investing in nuclear energy and the Mohammed bin Rashid Al Maktoum Solar Park, Dubai is working towards achieving its goal of becoming a sustainable city and reducing its carbon footprint.
