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:
B. - 5.71%
Explanation:
Given that
Purchase price = 1000 × 35 = 35000
Selling price = 1100 × 30 = 33000
Recall that
ROI = Net profit/total investment × 100
And that
Net profit = selling price - purchase price
= 33000 - 35000
= -2000
Therefore,
ROI = -2000/35000 × 100
= - 0.05714 × 100
= - 5.71 %
Thus, total return on investment is -5.71%
Answer:
0.17
Explanation:
The computation of expected return in investment is shown below:-
Expected return in investment = (Expected return of outcome 1 × Probability of outcome 1) + (Expected return of outcome 2 × Probability of outcome 2) + (Expected return of outcome 3 × Probability of outcome 3)
= (0.15 × 0.50) + (0.25 × 0.30) + (0.10 × 0.20)
= 0.075 + 0.075 + 0.2
= 0.17
Therefore for computing the expected rate of return we simply applied the above formula.
Answer:
A
Explanation:
The list contains more weaknesses than strengths
The list of weaknesses are:
Excess manufacturing capacity relative to market; If you are producing more than you are selling then its a weakness
Large inventories; that dont sell its a weakness
Lack of management depth; means that management does not have a proper foundation
Management turnover; if you keep changing management it will affect the company as skilled workers will be leaving
The list of strengths are:
Cost advantages; cost advantage against your competitors is an added strength
Market leadership; having a large market share is equally an advantage
