Calculate the change in the kinetic energy (KE) of the bottle when the mass is increased. Use the formula
KE = one half.mv2, where m is the mass and v is the speed (velocity). Assume that the speed of the soda bottle falling from a height of
0.8 m will be 4 m/s, and use this speed for each calculation.
Record your calculations in Table A of your Student Guide.
When the mass of the bottle is 0.125 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.250 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.375 kg, the KE is
kg m2/s2.
When the mass of the bottle is 0.500 kg, the KE is
kg m2/s2.
Answers
1. The kinetic energy of the bottle is 1 Kg.m²/s²
2. The kinetic energy of the bottle is 2 Kg.m²/s²
3. The kinetic energy of the bottle is 3 Kg.m²/s²
4. The kinetic energy of the bottle is 40 Kg.m²/s²
How do I determine the kinetic energy?The kinetic energy can be obtain as illustrated below:
1. For mass 0.125 Kg
Mass (m) = 0.125 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.125 × 4²
Kinetic energy = 1 Kg.m²/s²
2. For mass 0.250 Kg
Mass (m) = 0.250 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.250 × 4²
Kinetic energy = 2 Kg.m²/s²
3. For mass 0.375 Kg
Mass (m) = 0.375 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.375 × 4²
Kinetic energy = 3 Kg.m²/s²
4. For mass 0.500 Kg
Mass (m) = 0.500 KgVelocity (v) = 4 m/sKinetic energy (KE) =?KE = ½mv²
KE = ½ × 0.500 × 4²
Kinetic energy = 40 Kg.m²/s²

The change in kinetic energies are 1 \(kg m^{2}/s^{2}\), 2 \(kg m^{2}/s^{2}\), 3 \(kg m^{2}/s^{2}\), and 4 \(kg m^{2}/s^{2}\) respectively as the mass of the bottle is changed as 0.125kg, 0.250kg, 0.375kg, and 0.500kg.
Given the velocity v=4m/s.
KE=\(1/2 mv^{2}\)
Here KE represents the Kinetic energy of the bottle, m represents the mass of the bottle which is varying time to time, and v represents the velocity of the bottle which is constant over time.
For the first case:
Given mass m=0.125kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.125)*(4)²
=1 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.125kg is 1 kg m²/s².
For the second case:
Given mass m=0.250kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.250)*(4)²
=2 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.250kg is 2 kg m²/s².
For the third case:
Given mass m=0.375kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.375)*(4)²
=3 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.375kg is 3 kg m²/s².
For the final case:
Given mass m=0.500kg
∴KE=\(1/2mv^{2}\)
=1/2*(0.500)*(4)²
=4 \(kg m^{2}/s^{2}\)
Hence the change in kinetic energy of the bottle when it became 0.500kg is 4 kg m²/s².

I live in United Arab Emarates/Dubai
Answers
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.

Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
Answers
Answer: 1. Material being transported 2. The temperature of the material being transported 3. How long the pipes will be there (lifespan)
Explanation: 1. - The pipe builder should consider the material being transported to choose the correct material of the pipes to use, so they last long and can hold the material.
2. - Similar to 1, the pipe builder should consider the temperature of the material to choose the correct material of the pipes to use, so the pipes don’t break and function properly.
3. - If the pipe builder uses a material that can hold the material, that’s great! If that material will last a short time, it would not work if the pipes were to be used for a long time.
The things you said before about viscosity, density, and pressure are also correct. The correct answers are mainly talking about factors of the material being used in the pipes.
