Answer:
Explanation:
Block on the table m(A) = m1,
block on the cord m2,
the coefficient of static friction is k1=0.4,
the coefficient of kinetic friction is k2 =0.28
(a)
Block A:
T = F(fr) = k1 •N = k(s) • m1 •g,
Block B: T = m2•g.
k1 • m1 •g= m2•g,
m1 = m2/k(s) = m2/0.4.
(b)
Block A:
T = F(fr) = k2 •N = k2 • m1 •g,
Block B:
T = m2•g.
k2• m1 •g= m2•g,
m1 = m2/k2 = m2/0.28.
Answer:
"Try something and if it doesn't work, admit it and try something else."
Explanation:
When I took US Government, my teacher always emphasized that FDR was probably the best American President, and things like this really show why he admired him so much. Can you imagine those words coming out of the mouth of a modern politician?
Many people like to compare President Obama's first term with FDR's first term, but I believe that Obama had it easier. Not because the recession wasn't bad, but because it was fresh and new. President Bush's handling of the crisis was disastrous, but they messed up only for about one year. When FDR took office, the depression had been around for several years, so the negative effects were much greater.
When FDR took office the country was ravaged and nobody was sure that the new policies would work or not, or even what policies they should have implemented. That is why they engaged in a trial and error type of strategy where several options were explored to try to see what could work and what couldn't.
Answer:
the value of the MktRS (market rate of substitution) is 0
Explanation:
The computation of the market rate of substitution is shown below:
Since it is mentioned that
You like apples half as pears
So the equation would be
X = 1 ÷ 2 Y
X ÷ Y = 1 ÷ 2
Now the market rate of substitution of the price is
= $2 ÷ $4
= 1 ÷ 2
So,
= 1 ÷ 2 - 1 ÷ 2
= 0
Hence, the value of the MktRS (market rate of substitution) is 0
The same is to be considered
I’m not sure about the first one (my best guess is B.) but the second one is A.
Structural Unemployment is one that is permanent or long lived and Cyclical Unemployment does not have enough demand in the economy.
Explanation:
Structural unemployment results with a permanent dislocations within markets and a mismatch between skills in growing company needs. When the overall goods and service in an economy cannot support full employment that results with Cyclical unemployment.
