Answer:

39,200J

Explanation:

just took the test

The meteor's potential energy if it has a mass of 10kg at an altitude of 400 m will be 39200 J

Potential Energy that depend upon the relative position of various parts of system . It is an energy possessed by an object by virtue of its position or configuration.

mass(m)  = 10kg

g (acceleration due to gravity) = 9.8m/s^2

altitude(height (h)) = 400m

Meteor's Potential energy = m * g * h

                                           = 10 * 9.8 * 400 = 39200 J

correct option will be a) 39200 J

On the position-time graph, the value of the acceleration slope indicates the object. Hence, option B is correct.

Acceleration is the rate of change, including both speed and direction of velocity, over time. Whenever something moves faster or slower in a straight line, it is said to have been accelerated. So because direction is always shifting, moving on a circle accelerates even while the speed is constant.

It is a vector quantity, since acceleration has both a magnitude and a direction. Another vector quantity is velocity. The velocity vector change over a specific period of time, divided by that period of time, is the definition of acceleration. Instantaneous acceleration is determined by the upper bound of the ratio of the change in velocity over a particular time interval to the interval of time as that of the time interval approaches zero.

Therefore, this concludes that option B is correct.

Answer: Explanation:

Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

C segment of the graph shows that the car is slowing down.

The rate at which a body's displacement changes in relation to time is known as its velocity. Velocity is a vector quantity with both magnitude and direction. SI unit of velocity is meter/second.

In the given graph, Velocity of varying with time. When the car is slowing down, the slope of the graph is negative in this region.

According to figure: segment C and segment E has negative slope.   Hence, according to the option: C segment of the graph shows that the car is slowing down.

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.

Archimedes'  principle states an object submerged in liquid experiences an upthrust equal to the weight of the displaced liquid.

As per the Archimedes' principle, "A body immersed in a fluid, whether partially or totally submerged, experiences an upward buoyant force that acts at the center of mass of the displaced fluid and is equal to the weight of the fluid that the body displaces."

A submerged object feels more pressure on its bottom surface than its top surface when it is partially or entirely submerged. There is an upward push as a result of this. Upthrust  or buoyant force is the term for this force.

Hence, Archimedes'  principle states that an object submerged in liquid experiences  an upthrust equal to the weight of the displaced liquid.

Mark me as branliest if it is correct

Answer:

Explanation:

When two objects are in thermal equilibrium they are said to have the same temperature. During the process of reaching thermal equilibrium, heat, which is a form of energy, is transferred between the object

which means that it refers to transfer through a selectively permeable partition, the contact path.[1] For the relation of thermal equilibrium, the contact path is permeable only to heat; it does not permit the passage of matter or work; it is called a diathermal connection. According to Lieb and Yngvason, the essential meaning of the relation of thermal equilibrium includes that it is reflexive and symmetric. It is not included in the essential meaning whether it is or is not transitive. After discussing the semantics of the definition, they postulate a substantial physical axiom, that they call the "zeroth law of thermodynamics", that thermal equilibrium is a transitive relation. They comment that the equivalence classes of systems so established are called isotherms

Answer:

Human activities, especially the burning of fossil fuels like coal, oil, and natural gas, are primarily to blame for the rise in carbon dioxide levels over the past 100 years. Carbon dioxide is produced as a byproduct of combustion when these fossil fuels are burned for transportation, industrial processes, energy production, and other uses. Together with other greenhouse gases, this human-caused release of carbon dioxide has significantly boosted atmospheric carbon dioxide concentrations, causing the greenhouse effect and amplification of global warming and climate change.

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.
