A stone is dropped from rest from the top of a $20\text{ m}$ tower. Its speed on hitting the ground is ($g = 10\text{ m/s}^2$):
Using $v^2 = u^2 + 2gh = 0 + 2(10)(20) = 400$
$v = \sqrt{400} = \mathbf{20\text{ m/s}}$
The ester formed from a fatty acid and a long-chain alcohol is called:
Waxes are esters of long-chain fatty acids with long-chain alcohols. Acylglycerols (fats/oils) are esters with glycerol. Phospholipids have a phosphate group.
A house building advance of Rs. 2 million is paid to employees. In accounting terms, this payment is classified as a:
An advance paid to employees (such as a house-building advance) creates a receivable for the organization — the employee owes the money back. It is therefore recorded as an Asset (specifically a long-term receivable or loan to employees) on the balance sheet. It is not an expense until it is written off or adjusted, so it is neither revenue expenditure nor capital expenditure in the traditional sense.
Naegele's Rule formula:
\[\text{EDD} = \text{LMP} - 3\,\text{months} + 7\,\text{days} + 1\,\text{year}\]
Or equivalently: Add 9 months and 7 days to LMP
Calculation:
- LMP: 10th September
- Subtract 3 months: 10th June
- Add 7 days: 17th June
- Add 1 year (next year)
Therefore, EDD = 17th June (next year)
Normal pregnancy duration: \(280\,\text{days}\) or \(40\,\text{weeks}\) from LMP \(= 266\,\text{days}\) from conception.
Important caveat: Naegele's rule assumes a regular 28-day cycle with ovulation on Day 14. Adjust for irregular cycles accordingly. Ultrasound (especially first trimester CRL) is more accurate for dating.
