Response:
1) g=31.87ft/s^2
2)m=120
W=119.64lbf
Clarification:
initial segment
the weight of an object with a specified mass is determined using the equation
W=mg
we need to convert 120lb into slug
m=120lbx1slug/32.147lb=3.733slug
calculating for g
g=W/m
g=119/3.733=31.87ft/s^2
subsequent segment
the mass remains unchanged
m=120lb=3.733slug
Weight
W=3.733slug*32.05ft/s^2=119.64lbf
Answer:
The Python code is provided below with suitable comments
Explanation:
# convert list to set
male_names = set(['Oliver','Declan','Henry'])
# get name for removal and addition from user
remove_name = input("Enter remove name: ")
add_name = input("Enter add name: ")
# remove specified name from set
male_names.remove(remove_name)
# add new name to set
male_names.add(add_name)
# sort the resulting set
a = sorted(male_names)
# output the sorted set
print(a)

It is not feasible to install the wires within the conduit. Explanation: The given dimensions show that the total area is 2.04 square inches while the wires occupy 0.93 square inches. The maximum allowable fill for the conduit is 40%. To determine if placement is possible, compute the conduit’s area at 40% which equates to 0.816 square inches, less than the required area of the wires.
Answer:
t = 5.27 years
Explanation:
Firstly, the corrosion penetration rate is defined by the formula;
CPR = (KW)/(ρAt)
Where;
K = constant based on exposed area A.
W - mass lost over time
t- duration
ρ - density
A - area exposed
From the problem, we have;
W = 7.6kg or 7.6 x 10^(6) mg
CPR = 4 mm/yr
ρ = 4.5 g/cm³
Area = 800 cm²
K is a constant valued at 87.6cm
Rearranging the CPR formula to isolate t, we derive;
t = KW/(ρA(CPR))
t = (87.6 x 7.6 x 10^(6))/(4.5 x 800 x 4) = 46233.3 hours
The duration in question needs to be expressed in years.
Thus, converting hours to years;
There are 8760 hours in a year.
Therefore;
t = 46233.3/8760 = 5.27 years.
