Large scale electrical energy production largely depends on the use of turbines. Nearly all of the world's power that is supplied to a major grid is produced by turbines. From steam turbines used at coal-burning electricity plants to liquid water turbines used at hydro-electric plants, turbines are versatile and can be used in a number of applications. There are also gas turbines that com bust natural gas or diesel fuel for them to refuse. remote locations or where a large backup power supply is required.
water that was contaminated with lead from lead pipes. During this time, the
city claimed the water was safe to drink. Which of the following is an action
the city could have taken to keep the water safe?
O
A. Regularly test the water in residents' homes.
O
B. Ignore residents' requests to test the water.
O
C. Have city employees drink the water publicly.
D. Monitor the water quality in a neighboring area.
O
Answer: Option A
Explanation:
The water should regularly be checked after a certain period of time. There are many chances that the water that is suitable for drinking gets polluted which needs to have a watch on it.
The water that is supplied in the residential area should be checked time to time so that the contamination in the water can be known on time and precautions should be taken according to them.
Hence, the correct answer is option A
Answer:
A
Explanation:
regularly testing the waters in the residents home will definitely improve water purity in the neighborhood
b. plant roots, rainfall, temperature
c. Sunlight, soil ph, native animals
Answer: C. False colors are added to images to make some structures more noticeable.
False color refers to the special photography condition. This technique utilizes visible light range of the elctromagnetic spectrum to develop photograph. A false color image depicts an object in colors that differs from the actual color of the objects. This is used to capture the image of objects which cannot be detected in normal photographic techniques. It is a potent aerial photographic technique, which is used to capture large area of a region. It gives a definite color to vegetation, soil cover, river and other water body in the image.
False colors are added to images to make some structures more noticeable is the most accurate option because of the following reasons:
1. Electron microscope does not use beam of light to develop image but focuses beam of electrons to develop image.
2. Compound microscope does not use beam of electrons to develop image.
4. Electron microscope cannot be used for observation of living organisms, as high energy electron beam to develop image will be lethal for these living organisms.
Water can absorb a large amount of energy while producing only small changes in temperature because water has a high specific heat.
