Which of the following are examples of energy sources
A. Water dam
B. Coal- fired generator
C. Solar panel array
D. Nuclear power reactor
E. Sea salt
F Gasoline
i don't want to see any links
If i do you will be reported
Answer: A. Water dam
B. Coal- fired generator
C. Solar panel array
D. Nuclear power reactor
F. Gasoline
Explanation:
Water dam is a source of hydroelectrical energy as the energy produced by the high speed water currents can be used to generate electrical energy.
Coal fired generator is a source thermal energy.
Solar panel array converts the heat energy from the sun into electrical energy.
Nuclear power reactor converts the thermal energy from the radiations generated after the fusion and fission reactions of the heavy atoms in a nuclear reactor. The thermal energy is converted into electrical energy.
Gasoline is a source of thermal energy which is used to run the machine or vehicle. This way thermal energy is converted into mechanical energy.

A system that captures incoming solar radiation, stores it, and distributes it throughout a building is called
active solar heating
photoelectric heating
cell heating
passive solar heating
Answer: Active solar heating
Explanation:
Active solar heating is a design which is used for the purpose of storage of solar heat for household purposes. The solar heat is used for heat up the liquid and the energy is transferred to the interior space of the house for later use. It distributes the heat throughout the building. Passive solar heating used for heating and cooling of the building but not reliable for storage purposes. Photoelectric heating convert the incident solar heat into electrical energy. Cell heating is a technology in which the thermal energy in a cell is converted into mechanical energy and it is used in machines.
True or False? In the electron flow theory, electrons flow from the positively charged body to the negatively charged body.
I think it's false because the theory states that electrons flow from negative to positive. Since electrons are negatively charged, it follows that they are attracted by positively charged bodies and repelled by negatively charged bodies.
Answer:
false
Explanation:
write a paragraph on how iron and copper(separately) is manufactured, what it consists of and processes that it went through to be usable in its current form
Answer:
Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an iron-rich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.
Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper. ... Regardless of the ore type, mined copper ore must first be concentrated to remove gangue or unwanted materials embedded in the ore. The first step in this process is crushing and powdering ore in a ball or rod mill.
How does an engine work?
Answer:
The engine consists of a fixed cylinder and a moving piston. The expanding combustion gases push the piston, which in turn rotates the crankshaft. ... After the piston compresses the fuel-air mixture, the spark ignites it, causing combustion. The expansion of the combustion gases pushes the piston during the power stroke.
Answer:
an internal combustion engine works by combination air fuel and spark all at the right time as well as compression to cause an explosion and push the piston back down and spin the crank shaft wich goes to output

Explanation:
10. Technician A says that the powertrain control module (PCM) uses the manifold absolute pressure (MAP) sensor to determine the load on the engine and the
amount of fuel needed. Technician B says that, at idle, the MAP sensor voltage will be higher at high altitudes than when at sea level. Who is correct?
O A. Technician A
O B. Technician B
O C. Both Technicians A and B
OD. Neither Technician A nor B
Answer:
your answerbis both technician a and b
Both Technicians A and B because manifold absolute pressure (MAP) sensor can determine the load on the engine.
What is the manifold absolute pressure?The manifold absolute pressure sensor (MAP sensor) serves as one that works with intake air pressure which helps to set out the air and fuel quantities required for the ignition cylinders.
Therefore, the MAP sensor voltage will be higher at high altitudes and determine the load on the engine.

Jack has been concerned about the rapidly changing green regulations in his state and his ability as a mechanical engineer to keep up with developments in his field relating to green requirements. He wants to talk to his boss about taking a professional sabbatical to increase his knowledge of green mechanical engineering practices. How do you predict Jack will try to convince his boss to agree? (Select all that apply.)
a. Identify how greater knowledge of green mechanical engineering areas, such as robotics or waste management, could extend the company’s service offerings.
b. Explain how a better knowledge of integrated mechanical systems could help the company provide more energy-efficient options to customers.
c. Describe how a smarter selection of more efficient, forward-thinking equipment could help the company’s bottom line.
d. Warn that with regulations and green technology changing so fast, the potential for poor implementation and mistakes is large
Answer:
Option A, B and D
Explanation:
Jack can easily convince boss if he focus around two major aspects of the company
a) Revenue enhancement - Jack must outline the benefits of his research that can be used to improvise customer offerings and hence can be further used to devise more energy-efficient options to customer
b) Reduction in mistakes - Issues such as poor implementation can be avoided with better approach and understanding.
Hence, option A, B and D are correct
