A nation's nominal GDP is $1.5 trillion with an inflation rate of 5%. ∴ Real GDP is 30 trillion.
<u>Explanation:</u>
Key Terms
GDP deflator: A measure of the level of prices of all new, domestically produced, final goods and services in an economy. It is calculated by computing the ratio of nominal GDP to the real measure of GDP.
real GDP: A macroeconomic measure of the value of the economy’s output adjusted for price changes (inflation or deflation).
nominal GDP: A macroeconomic measure of the value of the economy’s output that is not adjusted for inflation.
GDP deflator( inflation rate = 5% ) =
Inflation rate =
trillion
∴ Real GDP is 30 trillion.

Answer:
A. Attractive
B. ( μ₀I² ) / ( 2πd )
Explanation:
A. We know that currents in the same direction attract, and currents in the opposite direction repel, according to ampere's law. In this case the current in the two wires are flowing in the same direction, and hence the force between the two wires are attractive.
B. Suppose that two wires of length and both carry the current in the same direction ( given ). In the presence of a magnetic field produced by wire 1, a force of magnitude m say, is experienced by wire 2. The magnitude of the magnetic field produced by wire 1 at distance say d, from it's axis, should thus be the following -
= μ₀I / 2πd
The force experienced by wire 2 should thus be -
= I( )
= I Sin( 90 )
= I ( μ₀I / 2πd )
Therefore the force per unit length experienced by wire 2 toward wire 1 should be ...
( / ) = ( μ₀I² ) / ( 2πd ) ... which is our solution
15 = a+(3-1)d
23 = a+(7-1)d
simultaneous eqs. solve for a and d
