Answer:

Option d - 204 m

Step-by-step explanation:

Given : The atmospheric pressures at the top and the bottom of a building are read by a barometer to be 96.0 and 98.0 kPa. If the density of air is 1.0 kg/m³.

To find : The height of the building ?

Solution :

We have given atmospheric pressures,

$P_{\text{top}}=96\ kPa$

$P_{\text{bottom}}=98\ kPa$

The density of air is 1.0 kg/m³ i.e. $\rho_a=1\ kg/m^3$

Atmospheric pressure reduces with altitude,

The height of the building is given by formula,

$H=\frac{\triangle P}{\rho_a\times g}$

$H=\frac{P_{\text{bottom}}-P_{\text{top}}}{\rho_a\times g}$

$H=\frac{(98-96)\times 10^3}{1\times 9.8}$

$H=\frac{2000}{9.8}$

$H=204\ m$

Therefore, Option d is correct.

The height of the building is 204 meter.

The length of the rectangle is 8cm longer than the width.

masya89 [10]

The length of the rectangle is 8cm longer than the width.
l=w+8
If the length of the original rectangle is increased by 6cm and the width is increased by 3cm the perimeter is 76cm.
p=76=((l+6)+(w+3))*2=(l+6+w+3)*2=(l+w+9)*2

to solve this substitute l=w+8 into the p= equation:
p=76=((w+8)+w+9)*2=
76=(2w+17)*2
76=4w+34
42=4w
10.5=w

l=w+8=10.5+8=18.5
