Define the following terms: a) Heating effect of electric current b) Magnetic effect of electric current. c) Electric fuse. d) Transpiration e) Electromagnet
Please answer ASAP, the one who is the correct will get brainliest
Explanation:
heating .....- The reason behind the heating effect of electric current is when the current passes through a conductor the electrons have to face the resistance of the conductor which results in the loss of energy and this loss of energy gets converted into heat energy.
magnetic.......- Magnetic effect of electric current - " The production of magnetic field around a conducting wire when electric current is allowed to flow through it, is called magnetic field of electric current."
electric...... - The fuse is a device used in an electrical circuit for protecting electrical devices against overloads and short circuit. It is the simplest and cheapest devices used for interrupting an electrical circuit under short circuit or excessive overload current magnitudes.
transpiration... - the process of water passing out from the surface of a plant or leaf
electromagnet... - a soft metal core made into a magnet by the passage of electric current through a coil surrounding

I live in United Arab Emarates/Dubai
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.

kg at an altitude of 400 m?
O A. 408 J
O B. 7,840,000 J
O C. 2J
O D. 39,200 J
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
What is potential energy ?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

Answer:
1. 5 ft-lbs
2. 600 ft-lbs
The power of the first equation is 5 ft-lbs/sec and the power of the second equation is 10 ft-lbs/sec.
The power is a proportion of how rapidly work is being finished. It is the rate at which energy is moved or work is performed. The unit of force is watts (W), which is comparable to joules each second (J/s).
To compute power, we utilize the equation P = W/t, where P is power, W is work, and t is time. Work is how much energy moved when a power is applied over a distance, and it is estimated in foot-pounds (ft-lbs) or joules (J).
In the primary condition, the power is determined by partitioning 250 ft-lbs of work when it took to accomplish the work, which is 50 seconds. Thusly, the power is 5 ft-lbs/sec.
In the subsequent condition, we first proselyte 4 minutes to seconds, which is 240 seconds. Then, at that point, we partition 2400 ft-lbs of work by 240 seconds to get a force of 10 ft-lbs/sec.
The units for power are dependably ft-lbs/sec or J/s, and they address how much work done per unit time.

What two gases in the atmosphere do animals and plants need to breathe and grow?
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.

Answer:
The speed of sound varies greatly depending upon the medium it is traveling through. ... The more rigid (or less compressible) the medium, the faster the speed of sound. The greater the density of a medium, the slower the speed of sound. The speed of sound in air is low, because air is compressible

Describe 3 factors an engineer should take into consideration when choosing material for building the pipes in a pipeline
Gr. 8
Think it has something to do with Viscosity, Density, and Pressure but not sure what
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.
