<span>A recent study has shown that children who are conceived in the winter months up until March in the US are 10% more likely to develop autism than those conceived in other months. The reason might be that there is a greater occurrence of infectious diseases in the winter months which may expose the mother to pathogens.</span>
Explanation:
Menes sent an army down the Nile and defeated the king of Lower Egypt in battle. In this way Menes united the two kingdoms.
The object must move with the speed of 
times to approximately seeing that it is contracted to exactly half of its actual length.
<h3>How is this calculated?</h3>
The length contraction experimented by the object as it approaches lightspeed, in meters per second, is described by Lorentz contraction formula:
Here, v is the current speed m/s
c is the speed of light in m/s
L' is the length of the object at rest in m
L is the length of the object at the current speed in m
Now we know that
and 
then,
Hence, r = 
Therefore, the answer is the object must travel at a speed of times the lightspeed to be contracted to one-half its proper length.

Indicate whether the following statements are "True" or "False" regarding the concept of gross income.
a. While the Constitution grants Congress the power to tax income, it does not define the term.
b. The Supreme Court has held that there is no income subject to tax until the taxpayer has recovered the capital invested.
c. Economists measure income (economic income) by first determining the fair market value of the individual's net assets (assets minus liabilities) at the beginning and end of the year (change in net worth).
d. Accounting and tax rules regarding income are the same.
e. The accounting concept of income is founded on the realization principle.
f. Gross income is not limited to cash received.
Answers:
a. True
b. True
c. True
d. False
e. True
f. True
Explanation:
1.The constitution of the United States allows for power to tax income however it doesn't define tax.
2.income is not subject to tax until there is profit from capital invested as ruled by the Supreme Court of the United States
3. Measurement of income in Economics involves applying the concept of fair value to measure income at the beginning and end if the year and notice any changes that may have occurred
4. Accounting and tax rules regarding income are not the same. Accounting however complies with tax rules for accounting purposes.
5.the realization principle involves income earned or losses incurred(not necessarily received in cash or given out)
6.Gross income encompasses all(recognizable) earned income for the period(cash or not)
