Answer:
50 lb
Explanation:
Given,
The weight of astronaut's life support backpack on Earth (w) = 300 lb
Acceleration due to gravity on Earth (g) = 9.8 m/s²
Acceleration due to gravity on Moon = g'
We know that weight of an object on Earth is,
Similarly, weight on Moon will be
Thus the astronaut's life support backpack will weigh 50 lb on Moon.
It will be
E = mgh.
where h and g are constant thus
m can be written as 4/3πr^3*density
E = 4/3πr^3* density
E? = 4/3π(2R)^3* density
= 4/3π8r^3
thus the e will be 4/3π8r^3* density/4/3πr^3*density nd thus you get 8E ..
Answer:
Resource disposal or waste disposal is a crucial aspect of resource management.
Businesses in the manufacturing sector must develop a model of operations that allows an endless loop of internal recycling of waste and or processing waste resources into commercial resources.
A good example would be when an abattoir processes the internal organs of cows and goats with some waste gotten from rice mill into can food for dogs and canines. Waste from this secondary process can either be converted into organic manure to be sold to farmers or processed further for consumption at carnivorous fish farms.
