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:
The straight-line depreciation method and the double-declining-balance depreciation method:
Produce the same total depreciation over an asset's useful life.
Explanation:
The straight-line and the double-declining-balance depreciation methods are two of the four depreciation methods allowed by US generally accepted accounting principles (GAAP). The other two methods are sum of the years' digit and units of production. The straight-line method is calculated by subtracting the salvage value from the asset's cost and either dividing the depreciable amount by the number of years or applying a fixed rate on the depreciable amount. For the double-declining-balance method, 100% is divided by the number of years of the asset's useful life and then multiplying by 2 to obtain the depreciation rate. Depreciation expense is then calculated on the declining balance until the salvage value is left. This is why they produce the same depreciation over the asset's useful life.
Answer:
A,. 13.33%.
Explanation:
Return on Investment (ROI) which gives the efficiency of a particular investment
We were given invested capital amounted as $6,000,000, and operating expenses as $5,000,000
We can calculate net income by substracing equal sales revenue from operating expenses
net income can be calculated as = ($5000000-$420000)
= $800000
ROI can be calculated as
net income/Capital investment
$800000/$6000000
=. 13.33%.
I think the answer would be alone
