Answer:
he tension in an elevator cable is 10,000 N. The elevator itself has a mass of 500 kg.
Explanation:
To solve this problem it is necessary to apply the concepts related to
conservation of energy, for this case manifested through work and kinetic energy.


Where,
F= Force (Frictional at this case
)
d= Distance

Where,
m = mass
v = velocity
Equation both terms,




Replacing with our values we have that

1. energy conversion - The conversion of fuel into mechanical energy and dissipation of heat.
2. fluid distribution - the reach of fuel in every necessary part of the machine.
3. fluid control
- the amount of fuel given
4. work performance - maximum output that can be drawn
5. fluid conditioning - the process of confirming the liquid is clean, cool and dry.
Answer:
time required to mow lawn is 1274.06 minutes
Explanation:
given data
average mow = 1400 square meters each hour
area = 320000 square feet
to find out
How many minutes will take to mow lawn
solution
we know that here 1 square feet is equal to 0.092903 square meter
so 320000 square feet will be = 0.09203 × 320000 = 29728.9728 square meter
so time required is express as
time required = 
time required = 
time required = 21.23 hours
so time required = 21.23 × 60 min = 1274.06
time required to mow lawn is 1274.06 minutes
