A mass hangs from the ceiling by a spring. It takes the mass 700 ms to fall from its maximum height of 2.3m to its minimum height of 1.6m above the floor.

(a) At what height above the floor does the mass have zero acceleration?

(b) What is the maximum speed of this mass?

(c) If you start a timer ( t = 0) at the moment when the mass is falling below a height of 1.9m, then at what time t will the mass first reach a height of 2.1m?

I would like to make 3.8 M of Perchloric acid and, i have no idea how to do it since it is not my field of study.

But have to make 3.8 M of Perchloric acid because we need to make sampling fluid with it.

Sampling fluid contains 0.11~0.13 grams of 2,4-DNPH+1L of Acetonitrile+0.15 mL of 3.8 M Perchloric acid.

The Perchloric acid that i have right now is 70%, 99.999% trace metals basis, Cas:7601-90-3 HCIO4, MW:100.46 g/mol, in a bottle of 50 mL.

My colleague told me that it contains 2009.2 M of HCIO4 in 50 mL from the calculation; 100.46/0.05 L = 2009.2 M HCIO4

If this it right, how do i make 2009.2 M of HCIO4 to 3.8 M HCIO4 ???

please help.

Sky High Parachute Company sells parachutes. As of January 1, Sky High had no beginning merchandise inventory. In the first quarter of 2020, Sky High sold 6,500 parachutes. The company’s sales forecast for the remainder of 2020 (in units) is:

Quarter 2: 7,000        Quarter 3: 7,500          Quarter 4: 9,000

Sky High’s selling price is $400 per parachute. All sales are credit sales. Sky High collects 85% of its sales in the quarter in which it made the sales and the remaining 15% in the following quarter.

As of March 31/April 1, Sky High had 1,300 parachutes in its merchandise inventory that it had purchased for $340 each. Sky High expects to pay its vendor $340 per parachute for the remainder of the year. Sky High plans to have the following number of parachutes in its merchandise inventory at the end of the remaining quarters in 2020.

Quarter 2: 1,500        Quarter 3: 2,000          Quarter 4: 1,000

Sky High buys the parachutes on credit. It pays for half of its purchases in the same quarter as it purchases them and pays the remaining half in the following quarter. Sky High pays for all its other expenses in the same quarter as it incurs them.

Sky High’s budget for variable selling expenses is $10 per each parachute sold. Sky High’s budget for fixed selling, general and administrative expenses is $25,000 each quarter. The $25,000 budget includes $5,000 in depreciation expense each quarter.

Please prepare the following budgets for Sky High for the second quarter of 2020 (Each question is worth 4 points):

1. Sales in dollars
2. Purchases of parachutes in units and dollars
3. Selling and Administrative Expenses in dollars
4. Cash collections (receipts) budget in dollars
5. Cash payments (disbursements) budget in dollars

You own a company that sells high-end motorcycles. You are considering launching a new marketing campaign in an attempt to increases sales but you are unsure of when you should start it. You believe it makes the most sense to market more when the fewest number of people typically buy motorcycles. So, you decided to use your quarterly sales data from the past 2+ years to test to see if there is a difference in sales between the quarters and if so, which quarter had the lowest sales.

For this question, you will need to download the Sales Data and then use the data analysis tool pack in Excel to run an Anova: Single Factor Test. Note, you will need to install the data analysis tool pack on your computer. How to do this differs based on the type of computer you are using, but instructions can be found on google for both Mac and PC.

In most hospitals, most laboratory workers are certified technicians and a minority are assistants. Obviously, the salary of the former is much higher than that of the assistants. In an effort to reduce costs, a hospital plans to employ only a quarter of the laboratory staff as certified technicians, the rest are assistants. Explain the effect that the hospital's decision may have on the following variations: materials, labor, and indirect costs. Are you in favor or against the plan of the hospital? Explain

Hillyard Company, an office supplies specialty store, prepares its master budget on a quarterly basis. The following data have been assembled to assist in preparing the master budget for the first quarter:

1. As of December 31 (the end of the prior quarter), the company’s general ledger showed the following account balances:

2. Actual sales for December and budgeted sales for the next four months are as follows:

3. Sales are 20% for cash and 80% on credit. All payments on credit sales are collected in the month following sale. The accounts receivable at December 31 are a result of December credit sales.

4. The company’s gross margin is 40% of sales. (In other words, cost of goods sold is 60% of sales.)

5. Monthly expenses are budgeted as follows: salaries and wages, $37,000 per month: advertising, $59,000 per month; shipping, 5% of sales; other expenses, 3% of sales. Depreciation, including depreciation on new assets acquired during the quarter, will be $45,620 for the quarter.

6. Each month’s ending inventory should equal 25% of the following month’s cost of goods sold.

7. One-half of a month’s inventory purchases is paid for in the month of purchase; the other half is paid in the following month.

8. During February, the company will purchase a new copy machine for $3,200 cash. During March, other equipment will be purchased for cash at a cost of $81,000.

9. During January, the company will declare and pay $45,000 in cash dividends.

10. Management wants to maintain a minimum cash balance of $30,000. The company has an agreement with a local bank that allows the company to borrow in increments of $1,000 at the beginning of each month. The interest rate on these loans is 1% per month and for simplicity we will assume that interest is not compounded. The company would, as far as it is able, repay the loan plus accumulated interest at the end of the quarter.

Complete the cash budget. (Cash deficiency, repayments and interest should be indicated by a minus sign.)
