Answer:
Hello your question is vague hence I will provide a general answer on the importance of : Waste reduction, rationalization of consumption, reuse, recycling as ways of preserving the natural resources
answer :
Waste reduction : when we reduce the amount of wastage on items we use especially items produced from natural raw materials we will help preserve the natural resource because they can be used to produce varieties of other items
Reuse and recycling of waste products help keep our natural environment healthy thus preserving our natural resources.
Explanation:
Waste reduction, rationalization of consumption, reuse and recycling are all ways of preserving our natural resources

Answer:
a) P' = P_original, b) P ’= P_original + ρ g Δh
Explanation:
The expression for nanometric pressure is
P = ρ g h
where ρ is the density of the liquid and h is the height
a) we change the radius of the barrel, but keeping the same height
as the pressure does not depend on the radius it remains the same
P' = P_original
b) We change the barrel height
h ’≠ h
we substitute in the equation
P ’= ρ g h’
h ’= h + Δh
P ’= ρ g (h + Δh)
P ’= (ρ g h) + ρ g Δh
P ’= P_original + ΔP
In this case, the pressure changes due to the new height,
*if it is higher than the initial one, the pressure increases
*if the height is less than the initial one, the pressure is less
That's 299,792,458 meters per second.
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
