Answer:
B = 0.287 Tesla
According to thumb rule the direction of magnet is to the east.
Explanation:
F = BiL sin∅
note that F = mg
B = magnetic field
i = current
therefore,
mg = BiLsin∅
Make B subject of the formula
B = mg/iLsin∅
m/L = mass per length of the wire and it is given in gram per centimeter . It should be converted to kg per meter.
m/L = 0.440 g/cm
convert to kg/m = 0.440 × 0.001 kg × 100 m = 0.044 kg/m
B = 9.8 × 0.044 / sin 90 × 1.50 × 1
B = 0.4312/ 1.50
B = 0.28746666666
B = 0.287 Tesla
According to thumb rule the direction of magnet is to the east.

The raw materials or reactants of the photosynthetic process include
A. glucose and oxygen.
B. carbon dioxide and glucose.
C. carbon dioxide and water.
D. carbon dioxide and oxygen.
The raw materials or reactants of the photosynthetic process include carbon dioxide and water.
<h3><u>
Explanation:</u></h3>
The process by which the light energy obtained from the sun is converted into chemical energy is photosynthesis. This process takes place in all plants having chloroplast pigments. The raw materials of this process is water and carbon dioxide.
In the photosynthesis process water, carbon dioxide and minerals will be converted into oxygen and some organic compounds that are filled with energy. This acts as an energy source for the plants to survive. This process will not be possible in the absence of the chloroplast pigment.
Answer: C.) Horizontal sum of all the individual firm's supply curve
Explanation: A perfectly competitive market, is that in which sellers or suppliers of a certain product are numerous such that a slight increase in price, and demand could fall to 0. Here, an individual seller has no control over the price of commodities. The supply curve tells how much quantity will be produced at different prices. Therefore the market supply curve is determined by all individual sellers individual price in other to determine the overall quantity to be produced at varying market price. Prices are drawn horizontally from the y-axis to determine quantity produced at different prices for each indivudual seller which is summed to generate the market supply curve.
Answer:
TRUE
Explanation:
The CEO
's belief that he has placed his firm in a slow-cycle industry where <u>concerns about protecting unique competencies dominate concerns about market share,</u> is true
Basically, the CEO operates in a niche market as is reported in the scenario
<u>Niche marketing refers to competing within a narrowly defined market segment with a specialized offering.</u>
Most small businesses are generally not niche marketers; they simply have a very small share of a large segment <u>whereas niche marketers have a large market share in a small/tight segment.
</u>
Having therefore established his Niche business in a small segment where he has a large market share (otherwise it would not be a niche business), <u>the concerns will be about protecting unique competencies rather than market share</u>

Answer:
Option (D) is correct.
Explanation:
Value of Yahoo:
= Shares × Price
= 110 shares × $20
= $2,200
Value of General Motors(GM):
= Shares × Price
= 210 shares × $20
= $4,200
Value of Standard and Poorʹs Index Fund (SPY):
= Shares × Price
= 70 shares × $130
= $9,100
Total value = Value of Yahoo + Value of GM + Value of SPY
= $2,200 + $4,200 + $9,100
= $15,500
Therefore,
Portfolio weight of YHOO:
= Value of YAHOO ÷ Total value
= $2,200 ÷ $15,500
= 0.1419 or 14.19%
Portfolio weight of GM:
= Value of GM ÷ Total value
= $4,200 ÷ $15,500
= 0.2709 or 27.09%
Therefore, the portfolio weight of YHOO and GM are 14.2% (approx) and 27.1% (approx), respectively.
