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.

saw5 [17]

Answer:

C

Explanation:

A farmer would want to look at the economic status of the US because his goal is to sell as much wheat as possible and make the most profit. If he pays no attention to the economy and there's a recession but he still sells his wheat at the normal price, people whose stocks are going down and who are losing money will be unable to, and unwilling to, pay the price. Thus, the farmer must inspect the changing economic statuses of the US to determine the best and most effective way to market out his wheat to the public.

Changes in US racial patterns have no impact on the marketing of the farmer's wheat, so A is incorrect.

The number of births per year is also irrelevant, as is the general population growth numbers because these do not affect the way the farmer will market his crops, so B and D are incorrect.

Hope this helps!

MAXImum [283]

Answer:

b. list the average amount.

Explanation:

If your income varies, you should "list the average amount".

When a particular set of values vary, an average value is used. Average value is actually the estimated value which is found in two or more varying values. It gives an idea of what an expected value will be.

So, when income varies, the average amount is expected to be listed. This is done in order compensate even the lowest amount. So if two income varies, the average amount can be determined by adding the highest amount to the lowest amount, and dividing the outcome by 2.
