Question
Chapter 7, Problem 7.10P
Interpretation Introduction
Interpretation:
The maximum power that is theoretically available from the waterfall is to be calculated and whether it is sufficient to meet one’s needs is to be predicted.
Concept introduction:
A system contains mainly three forms of energy; kinetic energy, potential energy and internal energy. Kinetic energy is related to the translational motion of the system with respect to some reference (mostly earth). Potential energy is related to the position of system in a potential field. Internal energy is related to all the energy other than potential and kinetic.

b) A plot of land was explored and found to contain 1,000,000 grams of gold. The average goldconcentration was found to be 0.8 grams per ton.
A mine was set up on it and sluice boxes were used as the main gold recovery units and recovered200,000 g of gold from 80% of the ore. The concentration ratio of the sluice boxes was 10,000.The field was mined again. On this occasion bowl concentrators were used. The feed used wasestimated to be 800,000 tons and the concentration ratio of this unit was 20,000. 750,000 grams ofgold was recovered.

- A unique plant was discovered from the hot springs of Maquinit, Coron, Palawan. To study the activity of the plant, approximately 5.00 g of the fresh plant was finely cut and ground and then mixed with an extraction buffer to make up a total of 1.00 mL crude plant extract. Approximately 19.00 mL of water was added to the plant extract. To determine the protein concentration of the extract, a bovine serum albumin (BSA) stock solution with a concentration of 300 μg mL-1 was used and mixtures with the following compositions and absorbance readings were prepared: A 100 μL aliquot of the diluted plant extract was added with 400 μL of water and was subjected to Bradford assay. Determine the protein concentration, in mg mL-1, of the original 1.00 mL crude extract if the absorbance of the diluted aliquot extract acquired from the analysis is 0.234.arrow_forwardA unique plant was discovered from the hot springs of Maquinit, Coron, Palawan.

- 4) But the real angler continues, regardless of the local sage. What sort of tone does the author create by using the connotative effects of the word sage in paragraph 6? The word "sage" is used primarily as a joke, gently mocking the fishing guide who cannot force fish to A) appear or guarantee good fishing to a paying customer. Primarily, the author is creating None of awe or B) respect for the great wisdom and power that the Eiminate sage, or fishing guide, holds in his mind. The author is being highly critical, even condemning. of the ignorance of these so-called "sages who can't help fisherman catch fish. The word sage" in this context has no connotaive D) effect on the tone or meaning of this entire passage.arrow_forwarddoug began preparing laboratory surface disinfectant from chlorine bleach. he put on a chemical resistant apron and gloves and then removed the bleach container from the special chemical cabinet. he carefully placed the container on the laboratory benchtop and began to add the chlorine bleach to distilled water. nearby workers began complaining of burning eyes. doug was reprimanded by the supervisor.

They all resolved this issue by strictly banning the junk food in schools and to introduce healthy snacks and drinks’like soup, lassi, milk, etc. in school canteens. They also decided to make compulsory half an hour physical activities for the students in the morning assembly daily. After six months, Mr. Roy conducted the health survey in most of the schools and discovered a tremendous improvement in the health of students. After reading the above passage, answer the following: What are the values (at least two) displayed by Mr. Roy? As a student, how can you spread awareness about this issue? What are tranquilizers?

- 1) One of Dr. G’s CHEM 102 students is working part-time at a hardware store. A customer tells this student “I need a single stud (a wooden beam) from which I can cut two (2) pieces of 2.7m studs”. The student does the math, goes behind counter, and brings a stud cut to 5m length. Select the most sensible and scientific answer to this situation. A) 2.7 × 2 when operated as a significant figure multiplication, gets you 5 and the student is right. B) Hardware stores don’t comply with correct sig. fig. rules for measurements. C) The customer must pay for 5.4m worth; but he/she should only get 5m to take home. D) The word ‘Two (2)’ mentioned here carries infinite significance, so the student is wrong. E) The word ‘Two (2)’ mentioned here is not a ‘measurement’, therefore this is an example of a situation where there is disagreement between science and day-to-day life.arrow_forwardYour careless, clumsy lab mate has accidentally allowed carbon monoxide to leak out of a reactor, causing your lab’s CO monitor alarm to sound. After you quickly put on the appropriate Personal Protective Equipment, you find the leak and seal it. Then, you close your lab door, shut the windows, and call OSHA to report the hazard.When OSHA technicians arrive, they begin ventilating the 3000-ft3laboratory by pumping 25 ft3/min of fresh air into the room and removing the contaminated air at the same rate. They put a shop fan in the laboratory, such that the air is well-mixed. They also install a digital CO composition monitor, which currently reads 2 mol%. OSHA tells you that the laboratory is safe when there is less than 35 ppm of CO in the lab.How long must you wait to get back to work?arrow_forwardOn the occasion of World Health Day, Dr. Satpal organized a ‘health camp’ for the poor farmers living in a nearby village. After check-up, he was shocked to see that most of the farmers suffered from cancer due to regular exposure to pesticides and many were diabetic. They distributed free medicines to them. Dr. Satpal immediately reported the matter to the National Human Rights Commission (NHRC). On the suggestions of NHRC, the government decided to provide medical care, financial assistance, setting up of superspeciality hospitals for treatment and prevention of the deadly disease in the affected villages all over India. (i) Write the values shown by (a) Dr. Satpal (b) NHRC. (ii) What type of analgesics are chiefly used for the relief of pain of terminal cancer?
