Answer:
The elastic modulus of the steel is 139062.5 N/in^2
Explanation:
Elastic modulus = stress ÷ strain
Load = 89,000 N
Area of square cross section of the steel bar = (0.8 in)^2 = 0.64 in^2
Stress = load/area = 89,000/0.64 = 139.0625 N/in^2
Length of steel bar = 4 in
Extension = 4×10^-3 in
Strain = extension/length = 4×10^-3/4 = 1×10^-3
Elastic modulus = 139.0625 N/in^2 ÷ 1×10^-3 = 139062.5 N/in^2
Answer:
Expressions are made up of terms.
A term is a product of factors.
Coefficient is the numerical factor in the term
Before moving to terms like monomials, binomials, and polynomials, like and unlike terms are discussed.
When terms have the same algebraic factors, they are like terms.
When terms have different algebraic factors, they are unlike terms.

Answer:
The answer is "conditionally unstable"
Explanation:
The conditional volatility is really a condition of uncertainty, which reflects on whether increasing air is polluted or not. It determines the rate of ambient delay, which has been between humid and dry adiabatic rates. In general, the environment is in an unilaterally unhealthy region.
Classification dependent on ELR:
Larger than 10 
m Around 10 and 6 m or less 6 m volatile implicitly unreliable Therefore ELR is implicitly unreliable 9 m, that's why it is "conditionally unstable".
The equation is below:
10^9 m = 1 Gm
Answer:
True
Explanation:
Permanent electrical safety devices (PESD) acts as a layer of protection between the electrical worker and the hazardous voltage.
Permanent electrical safety devices (PESDs) are deployed to reduce the risks in isolating electrical energy.
Electrical safety can be improved if a worker determines a zero electrical energy state irrespective of any voltage exposure to themselves.
The given statement is true
