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:
export
Explanation:
Import is when goods and services are brought into a country from another country.
If people are buying goods from another country, a country must be selling it to them. The country selling these goods are exporting them.
Export is when a country sells goods to another country.
For example, if US buys cars from Germany. US is importing the cars while Germany is exporting the cars
Answer:
Actual level of activity which is 290,000 units
Explanation:
Although budgeted was 300,000 units, in order to understand the efficiency of labour in terms of the number of direct labour hours used, it must be flexed in order for it to be comparable.
for example they used only 135,000 units instead of budgeted which is 150,000 but although that is good, it does not tell us all the story, we will also consider the fact that they produced lesser quantities than planned which is 290,000 rather than 300,000.
