Answer:
ACCIDENT PREVENTION RECOMMENDATIONS
Fatal Fact made us to understand some of the prevention techniques as stated below.
1. Use approved ground fault circuit interrupters or an assured equipment grounding conductor program to protect employees on construction sites.
2. Use equipment that provides a permanent and continuous path from circuits, equipment, structures, conduit or enclosures to ground.
3. Inspect electrical tools and equipment daily and remove damaged or defective equipment from use until it is repaired.
Explanation:
In order to gain a better understanding of the answer above let explain some terms
Ground Fault Circuit Interrupters :
A ground fault circuit interrupter (GFCI), or Residual Current Device (RCD) is a type of circuit breaker which shuts off electric power when it senses an imbalance between the outgoing and incoming current. The main purpose is to protect people from an electric shock caused when some of the current travels through a person's body due to an electrical fault such as a short circuit, insulation failure, or equipment malfunction.
So the first statement is implying that in order to prevent this accident that this device (GFCI) should have been used in that construction site, or as an alternative before the construction commenced the company should have drafted a lay down conductor program(i.e. a step by step conductor program) that assured equipment grounding in order to protect employees on construction sites
Answer:
Hold the tape in place and go down to the end.
Explanation:
Answer:
T(water)=50.32℃
T(air)=3052.6℃
Explanation:
Hello!
To solve this problem we must use the equation that defines the transfer of heat by convection, which consists of the transport of heat through fluids in this case water and air.
The equation is as follows!

Q = heat
h = heat transfer coefficient
Ts = surface temperature
T = fluid temperature
a = heat transfer area
The surface area of a cylinder is calculated as follows

Where
D=diameter=20mm=0.02m
L=leght=200mm)0.2m
solving

For water
Q=2Kw=2000W
h=5000W/m2K
a=0.01319m^2
Tα=20C

solving for ts


for air
Q=2Kw=2000W
h=50W/m2K
a=0.01319m^2
Tα=20C
