Answer:
The time it will take to raise the temperature of 850 kg of steel from 15°C to 45°C is approximately 0.11064 hours
Explanation:
The given parameters are;
The mass of the steel = 850 kg
The temperature of the water of the ocean = 45°C
The temperature of the steel = 15°C
The heat capacity for steel, c = 0.46 kJ/(kg·K)
Therefore, the heat, ΔQ required to raise the temperature of 850 kg of steel from 15°C to 45°C is given as follows;
ΔQ = The mass of steel × The heat capacity for steel × The rise in temperature
ΔQ = 850 kg ×0.46 kJ/(kg·K) × (45 - 15)°C = 11730 kJ = 11730 × 10³J
The rate of heat transfer = 29.45 × 10³ W = 29.45 × 10³ J/S
Therefore, the time, t, it will take to absorb 11730 kJ is given as follows;
t = (11730 × 10³J)/(29.45 × 10³ J/S) ≈ 398.3 seconds
t ≈ 398.3 seconds = 398.3 seconds ×1/60 minutes/second × 1/60 hour/minute
t ≈ 0.11064 hours
The time it will take to raise the temperature of 850 kg of steel from 15°C to 45°C ≈ 0.11064 hours.
The proper way to start cutting materiala circular saw is to _.
Answer:
scissors?
Explanation:
Answer:
rev the saw to full speed and slowly move it forward into the material
Explanation:
There are many types of saws and one of which is the "circular saw." It functions by providing a frame for anything that you're working on.
When using a circular saw, it is very important to consider the precautions and the proper steps in using and handling it. It is important to rev the saw to full speed and slowly move it towards the material you're working on. This prevents the blade from being compressed. This results to a fine way of cutting through and gives you a well-cut output.

A machinist creates a solid steel part for a wind turbine. The part has a volume of 1015 cubic centimeters. Steel can be purchased for $0.29 per gram, and has a density of 0.795 g/cm3. If the machinist makes 500 of these parts, what is the cost of the steel, to the nearest dollar
Answer:
$234
Explanation:
[tex]cost=volume*density*cost per gram = 1015cm^{3} *0795g/cm^{3} *0.29dollars/g=234 dollars[/tex]
As per the given data, the cost of steel for 500 parts will be approximately $116891.
What is wind turbine?A wind turbine is a machine that converts wind's kinetic energy into electrical energy.
To find the cost of the steel for 500 parts, we need to first find the mass of steel required to make one part.
Density of steel = 0.795 g/cm^3
Volume of one part = 1015 cubic centimeters
Mass of one part = Density x Volume = 0.795 x 1015 = 806.425 grams
So, to make 500 parts, the total mass of steel required will be:
Total mass = 500 x 806.425 = 403212.5 grams
The cost of steel per gram is $0.29, so the total cost of the steel for 500 parts will be:
Total cost = Total mass x Cost per gram = 403212.5 x 0.29 = $116891.13
Rounding this to the nearest dollar, the cost of steel for 500 parts will be approximately $116891.
Thus, the answer is $116891.

!WILL GIVE BRAINLIEST!! Explain the difference in the work performed by an environmental scientist and a civil engineer during the development of a geothermal site.
Answer:
What is environmental science?Environmental science is a wide field that combines disciplines and methodologies from the biological, information, chemical and physical sciences to study the environment and the impact from external factors like urban development and population growth. Environmental scientists and professionals working in the field collect and analyze data from nature, small communities and large urban areas to determine an area's pollution and contamination risk. Through the collection and analysis of data from the environment, professionals can assess soil health, water usability and accessibility and other factors that can affect both citizens and the environment.
Explanation:
What is environmental engineering?Environmental engineering is a field in engineering where professionals focus on combining environmental science methods with engineering principles to develop and implement better infrastructure, technology and industrial operations that reduce the risk of environmental contamination and pollution. Environmental engineers may often collaborate closely with environmental scientists to apply data to designs that promote cleaner energy use, more efficient building activities and ecologically sound business practices.Additionally, environmental engineering often includes other fields that overlap to form a foundation for this career path. For instance, environmental engineers may also incorporate aspects of civil engineering, transportation and logistics, geotechnical engineering, chemical engineering and biology to develop strategies that reduce the risk of pollutants and contaminants from urban projects and other activities that can impact the environment.
Difference between these both engendering Even with the overlap in some of the collaboration and application methods of both environmental career fields, there are several key differences between environmental engineering and environmental science:Career focusOne important distinction between environmental science and engineering is the career focus. Environmental scientists focus on the collection and analysis of data and the assessment of hypotheses they make based on information they gather from the environment. Environmental engineers' focus is the application of the data scientists and technicians analyze in order to produce outcomes that reduce pollution, increase environmental efficacy and ensure construction projects comply with local, state and federal environmental policies. Environmental science gives information to engineering professionals with the goal of reducing the impacts of development and population growth.Essential job dutiesEnvironmental scientists and technicians may spend a majority of their careers working within laboratory settings to test environmental samples and form studies around the data they collect from the environment. Outdoors, environmental scientists study natural resources and elements for signs of contamination or pollution and collect samples for laboratory analysis.An environmental engineer, conversely, uses the information from environmental scientists to make decisions on project designs, mitigation strategies and construction activities. In addition, engineers collaborate with other professionals like urban planners and regional directors to plan projects that support environmental and community health and safety. The strategies engineers apply in their careers ultimately work to reduce and repair environmental impact and damage.Average salaryAccording to Indeed's salary information, the salary averages for an environmental scientist and environmental engineer also differ. While an environmental scientist can earn an average of $71,939 per year, an environmental engineer can have an earning potential of $83,893 per year. Several factors can affect the average income you can earn in both career fields, though. For instance, your degree level and experience level can impact your starting salary, and some employers may pay higher salaries for special certifications. Additionally, your location can also affect your earning potential, where some areas have higher income averages than others. And more
