Answer:
ρ = 1.08 g/cm³
Explanation:
Step 1: Given data
Mass of the substance (m): 21.112 g
Volume of the substance (V): 19.5 cm³
Step 2: Calculate the density of the substance
The density (ρ) of a substance is equal to its mass divided by its volume.
ρ = m / V
ρ = 21.112 g / 19.5 cm³
ρ = 1.08 g/cm³
The density of the substance is 1.08 g/cm³.
Density = mass/volume
Density = 81g/0.9cm³
Density = 90g/cm³

Answer:
water stored in a dam
Explanation:
when the water is in dam it is ready to move bit is not moving
a) Carbon and oxygen are chemically bonded in carbon dioxide.
The elements lose their individual identities in CO₂, and they always combine o the proportion C:O = 1:2.
You cannot separate the elements from each other by physical means.
Answer:
Pipe racks are construction in chemical and other industries plants, that support the pipe line, electric cables and instrument cable.
Explanation:
The pipe racks also used to support mechanical equipment as valve and vessels. You can transfer material between equipment and sorage or utility areas. Pipe racks aren´t only non-building constructions that have similiraties to the Steel buildings but also have additional loads style. The requirements found in the building codes apply and dictate some of the design requirements.
Some industry references exist to help the designer apply the intent of the code and follow expected engineering practices.
Pipe racks have design criteria: In most of the United States, the governing building code is the International Building Code.
Includes:
*Dead Loads
*Live Loads
*Thermal Loads
*Earthquake Loads
*Wind Loads
*Rain Loads
*Snow Loads
*Ice Loads
*Load Combinations
Also have Design Considerations:
*Layout
*Seismic
*Seismic System Selection
*Period Calculations
*Analisys Procedure
*Selection
*Equivalent Lateral Force Method Analysis
*Modal Response Spectra Analysis
*Drift
*Seismic Detailing Requirements
*Wind
*Pressures and Forces
*Coatings
*Fire Protection
*Torsion on Support Beams
