The energy transfer in terms of work has the equation:
W = mΔ(PV)
To be consistent with units, let's convert them first as follows:
P₁ = 80 lbf/in² * (1 ft/12 in)² = 5/9 lbf/ft²
P₂ = 20 lbf/in² * (1 ft/12 in)² = 5/36 lbf/ft²
V₁ = 4 ft³/lbm
V₂ = 11 ft³/lbm
W = m(P₂V₂ - P₁V₁)
W = (14.5 lbm)[(5/36 lbf/ft²)(4 ft³/lbm) - (5/9 lbf/ft²)(11 lbm/ft³)]
W = -80.556 ft·lbf
In 1 Btu, there is 779 ft·lbf. Thus, work in Btu is:
W = -80.556 ft·lbf(1 Btu/779 ft·lbf)
<em>W = -0.1034 BTU</em>
Answer:
The magnetic field at a distance x = 5 m is 1.59 nT
Explanation:
Length of the wire, L = 2 cm = 0.02 m
Current, I = 20 A
x = 5 m
Magnetic field at a distance x = 5 m due to an infinitely long wire is given by:
Answer:
Base quantities are the minimum numbers of the physical quantities. Base quantities are defined as the physical quantities which can not be defined in terms of other physical quanities. There are seven base quantities. Physical Quantitie Units Derived Quantities are defined as those physical quantities which are derived from the base quantities.
Explanation:
A physical quantity is a property of a material or system that can be quantified by measurement. A physical quantity can be expressed as the combination of a numerical value and a unit. For example, the physical quantity mass can be quantified as n kg, where n is the numerical value and kg is the unit. A physical quantity possesses at least two characteristics in common, one is numerical magnitude and other is the unit in which it is measured.
Distinguish between a basic physical quantity and a derived physical quantity giving an example of each. Answers. Basic physical quantities are quantities which can be obtained without derivation. e.g Temperature. While derived physical quantities are quantities which can only be obtained from other physical quantities.
A Safety Data Sheet (SDS) provides even more information on chemicals than a label: True.
<h3>What is a
Safety Data Sheet (
SDS)?</h3>
A Safety Data Sheet (SDS) can be defined as a text-based document (bulletin) that is developed to provide more information with respect to the chemical and physical properties of a chemical compound, substance or equipment such as:
Additionally, a Safety Data Sheet (SDS) contains information on the potential health hazards and safety precautions for proper use, handling, storage and transportation of a chemical compound, substance or equipment.
In conclusion, we can deduce that a Safety Data Sheet (SDS) provides even more information on chemicals than a label, which only contains lesser information about a product.
