Answer and Explanation:
The computation is shown below;
Given that,
Principal = P = $2000
As we know that
Future value (FV) = P × (1 + R)^n
here,
R = Rate of interest,
N = no of years
Now
A) N = 5, R = 5% = 0.05
FV = $2,000 × (1.05)^5
= $2,553
The Interest earned is
= $2,553 - $2,000
= $553
B) N = 10, R = 5% = 0.05
FV = $2,000 × (1.05)^10
= $3,258
The Interest earned is
= $3,258 - $2,000
= $1,258
C) N = 5, R = 10% = 0.10
FV = $2,000 × (1.10)^5
= $3,221
D) Option A
As in the part B the time period is 10 years as compared with the part A i.e. 5 years having the interest rate same
Also the cumulative interest would be greather than double as compared with part A
Answer:
16.9816 psia
Explanation:
To calculate the absolute pressure in the bottom of tube we need to sum the atmosferic and gauge pressure.
And the gauge pressure is given by the contributions of columns of water () and mercury(
), we can calculate the contribution of each column as:
(*)
where is the respective density, g gravity and h is height.
So we have all the data required to use the above equations (, height and density of each column) we only need to be carefully with the units.
For simplicity we can to express all pressure contributions in mmHg ( ,
and
). Note that the units "x" mmHg means the pressure at the bottom of a column of mercury of "x" mm high. For example, in this case we have a column 12.1 cm of Hg, that is a column of 121 mmHg (passing from cm to mm only requires multiply by 10) pressure exerted by that column is 121 mmHg.
Now pressure of 5.6 cm (56 mm) of water would be 56 mm of water, but it is not the same that mmHg, since the density of water is lower, the pressure exerted by 1 mm of water is lower than the exerted by 1 mm of Hg. The conversion between mmHg and mm of water is given by the relation between the densities.
And pressure of water in mmHg is
The absolute pressure is:
To pass to dyn/cm^2 units we need to use the equation (*)
Note: We need to use cm Hg for units coherence
Now passing from dyn/ to kN/
(or kPa) we need to consider that 1 dyn is
kN and 1
is
.
Now passing kN/ to psia. We need to consider that 1 psia is 6.89476.
