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.

faust18 [17]

Answer:

This is not necessarily evidence that the proportion of Americans who are afraid to fly has  decreaseddecreased  because belowbelow  0.10 because the proportion of sample, is nothing very close to 0.10.

Explanation:

n = 1100

p = 0.10

Using the formula np(1-p), we will have

= 1100(0.10)*(1 - 0.10)

= 1100*0.10*0.90

= 99

99 ≥ 10

This satisfies normal distribution condition. That is, proportion of sample are normally distributed.

At one extreme of the curve, the highest possible amount of one good is produced while zero quantity of the second good is produced . To produce more quantity of the second good, one has to produce less quantity of the first good. This illustrates trade off.
