A car moves with the speed of 120m/s for 4 minutes ,calculate the distance covered by the car​

Answers

Answer:

960 m

Explanation:

Given that,

Speed = 120 m/sTime taken = 4 minutes

We have to find the distance covered.

Firstly, let's convert time in seconds.

→ 1 minute = 60 seconds

→ 4 minutes = (4 × 60) seconds

→ 4 minutes = 240 seconds

Now, we know that,

→ Distance = Speed × Time

→ Distance = (4 × 240) m

→ Distance = 960 m

Therefore, distance covered is 960 m.

1) Explain the term fermentation

2) why is fermentation useful in making wine and beer

​

Answers

1. Fermentation is a metabolic process that produces chemical changes in organic substrates through the action of enzymes. In biochemistry, it is narrowly defined as the extraction of energy from carbohydrates in the absence of oxygen. The science of fermentation is known as zymology.

2. In general, the longer that fermentation goes on, the more sugar is converted into alcohol, resulting in a less sweet (or “drier”) and more alcoholic beverage. To produce beer, various grains are used instead of grapes as the source of sugars. ... This drying process converts the starches present in grain into sugars

Answer:

1.) Fermentation, chemical process by which molecules such as glucose are broken down anaerobically. More broadly, fermentation is the foaming that occurs during the manufacture of wine and beer, a process at least 10,000 years old.

A fixed mass of gas has a volume of gas of 25cm3. the pressure of the gas is 100kPA. the volume of the gas is slowly decreased by 15cm3 at a constant temperature. what is the change in the pressure of the gas?
a) 67kPA
b) 150kPA
c) 170kPA
d) 250kPA
give reasons

Answers

A fixed mass of gas has a volume of 25 [tex]cm^3[/tex], the pressure of the gas is 100 kPa, the volume of the gas is slowly decreased by 15 [tex]cm^3[/tex] at a constant temperature, and the change in pressure of the gas is 150 kPa, which is option b.

What is the calculation of the change in pressure?

PV = nRT (P= pressure of the gas, V =volume, n = number of moles of gas, R = gas constant, and T =temperature of the gas in kelvin)

Suppose the gas is an ideal gas and that the temperature is constant,

P1V1 = P2V2

Here P1 = 100 kPa, V1 = 25 [tex]cm^3[/tex], V2 = 10 [tex]cm^3[/tex],

100 kPa x 25 [tex]cm^3[/tex] = P2 x 10 [tex]cm^3[/tex]

P2 = (100 kPa x 25 [tex]cm^3[/tex]) / 10 [tex]cm^3[/tex]

P2 = 250 kPa

the change in pressure of the gas is,

ΔP = P2 - P1 = 250 kPa - 100 kPa = 150 kPa

The reason is that when the volume of a fixed mass of gas is decreased, the pressure of the gas increases proportionally, so here assuming that the temperature is constant it is calculated.

Hence, the volume of the gas is slowly decreased by 15 [tex]cm^3[/tex] at a constant temperature, and the change in pressure of the gas is 150 kPa, which is option b.

A. 13.3 m
B. 30 m
C. 5 m
D. 21.5 m

Answers

Answer:

Distance = 30 meters

Explanation:

Given the following data;

Speed = 1.5 m/s

Time = 20 seconds

To find the distance travelled;

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the formula;

[tex]Speed = \frac{distance}{time}[/tex]

Making distance the subject of formula, we have;

[tex] Distance = speed * time [/tex]

Substituting into the above formula, we have;

[tex] Distance = 1.5 * 20 [/tex]

Distance = 30 meters

The budget wil include operating, capital, cash and flexible budgets. The hospital is noted for its three fine programs: oncology (cancer), cardiac (heart), and rhinoplasty (nose jobs).Section AThe managers at Denison have been busy working. They have reviewed past records and considered changes in competition, the general economy, and overall medical trends. Using past charges and anticipated rates of medical inflation, they have also made a first attempt at setting thier prices.Based on a thorough review and discussion of these data, they have projected that next year they will have 240 patients. They expect 120 oncology patients, 80 caridace patients, and 40 rhinoplasty patients.The charge, of list price, for oncology patient will average $50,000. Cardiac patients will be charged on average of $40,000, and rhinoplasty, $25,000 per patient. However, those charges are not the actual amounts ultimately received.The amount the hospital receives depends on whether patients pay their own hospital bills or have healthcare insurance. Assume that private insurance companies pay the full charge or list price. However, Medicare and Medicaid have announced rates they will pay for the coming year as follow: oncology patients $40,000, cardiac patients $30,000, and rhinoplasty patients $10,000. Self-pay patients are supposed to pay the full charge, but generally 25 percent of self-pay charges become a bad credit. Note that bad credit are treated as an expense in healthcare. They may not be shown as a reduction lowering revenues. The full charge for self-pay patients is shown as revenues, and then the uncollectible amount is shown as an expense. No payment for charity care is ever recieved, and charity care is not shown s a revenue or expense.The payer mix is as follows: Private insurance Medicare/Medicaid Self-Pay CharityOncology 30% 50% 10% 10%Cardiac 20% 60% 10% 10%Rhinoplasty 10% 20% 60% 10%Gift shop revenue is projected to be $120,000 for the current year and is expected to remain the same. However, this revenue will increase or decline in proportion to charges in patient volume.Denison Hospital has an endowment of $1,000,000. It is invested as follows:a-$500,000 in 6 percent U.S. Governement Bonds that pay interest annuallyb-$250,000 in AT&T stock, which pays a dividend of 8 percent annuallyc-$250,000 in growth stocks that pay no dividendSection A requirements:1. Calculate patient revenue on an accural basis for the coming year. Subdivide revenue by program, and with each program subdivide it by type of payer.2. Calculate endowment revenue on an accural basis for the coming year.3. Prepare a revenue budget on an accural basis, including all sources of revenue discussed previously. The revenue budget does not have to show all of the detail from requirements 1 and 2, but should show each major source of revenue, such as patient services and endowment.Section BThe hospital expects to employ worker in the following departments Radiology Nursing Administration TotalManagers 100,000 200,000 200,000 500,000Staff 1,900,000 4,200,000 300,000 6,400,000Total 2,000,000 4,400,000 500,000 6,900,000Supplies are expected to be purchased throughout the year for the departments, as follows: TotalRadiology 360,000Nursing 160,000Administration 20,000Total 540,000Assume that all supply use varies with the number of patients.Denison Hospital currently pays rent on its building and equipment for $300,000 per year. Rent is expected to be unchanged next year. The rent is paid $75,000 each quarter.To better serve its patients, Denison would like to buy $500,000 of new oncology equipment at the start of the year. It would be paid for immediately upon purchase. The equipment has a 5-year life and would be expected to be used up evenly over that lifetime. Although the capital budget would normally include justification for why the equipment is needed, it is sufficient for our purpose to know that the capital budget for Denison is $500,000 and the equipment to be purchased has 5-year useful life. It will have no value left at the end of the 5 years. Denison charges the cost of its capital acquisitions on a straight-line depreciation basis. The means that the cost is spread out over the useful life, with an equal being charged as an expense, called depreciation expense, each year.Section B Requirements:1. Calculate expected bad debt expenses on an accural basis for the coming year2. Calculate an expense budget on a accural basis for the coming year.
