The correct answer is a substance that is composed of hydrogen atoms bonded to oxygen atoms
Answer:
49 m/s
Explanation:
This is the question from the document:
1. A bag dropped from a helicopter falls with an acceleration of 9.8m/s2. What is its velocity after 5s?
We can find the answer by using the equation a = (v-u) / t
Acceleration a = 9.81m/s2
initial velocity u = 0 m/s (the bag is only dropped, so there's no initial velocity already existing)
time t= 5s
final velocity v = unknown
9.8 = (v -0) / 5
v - 0 = 9.8x5
v = 49 m/s
Compaction is when sediments are buried deeply, which causes pressure because of the weight of the layers above them. This squashes the grains together more tightly. Cementation is where new minerals stick the grains together
Answer:
a)
b)
Explanation:
From the question we are told that
Diameter of hole 
Depth of hole 
Diameter of tank 
Generally the equation for pressure is mathematically given as


Where



Generally the level at which the water level will initially drop if the water is not replenished is mathematically given by

Therefore the level at which the water level will initially drop if the water is not replenished

Answer:
Flexible and responsive to the clients requests
Explanation:
Change in design is the alteration of the specification of a product based on present or current requirements, as such change in design can take place at any stage of a product life cycle.
However, it is more cost effective to make changes to the design at the early stages of a product than at the later stages, due to the cost incurred in making adjustments and the previous expenses incurred if the design that was later changed had moved into more advanced stages.
