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:
D they both will increase
Explanation:
Goodluck on that.

HDI includes life expectancy, education and per capita income indicator, which is a measurement that is used to rank countries, therefore suggesting that when the lifespan of the country is high the country's score of HDI is also high and thus the education level is high and the GDP per capita is also high as well.
The correct answer is the government regulations. The government
regulations are being placed and established by means of ensuring that the
market are able to run effectively and to be able to protect the consumers
through the regulations by which the government agencies are responsible for
regulating and implementing the policies.
