Answer:
Explanation:
1 hectare = 10^4 m^2
Area of pit, A = 75 hectare
convert hectare into m^2
A = 75 x 10^4 m^2
depth, d = 26 m
Volume of earth removed is V.
V = area of pit x depth
V = A x d
V = 75 x 10^4 x 26 = 1950 x 10^4 m^3
Convert cubic metre into cubic km
1 m = 10^-3 km
1 m^3 = 10^-9 km^3
So,
<span>Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. We do as follows:
</span><span>A. 1L
100 g /1L = 100 g/L
B. 0.10 L.
100g/0.10L = 1000 g/L ------> MOST DENSE SUBSTANCE
C. 100 L
</span>100g/100L = 1 g / L <span>
D. 10 L
</span>100g/10L = 10 g/L
Um I think it is D both gravity and inertia. Hope this helped
Answer:
Explanation:
The standard unit of displacement in the International System of Units ( SI ) is the meter (m).
All of the following apply the third law of motion except: D. taking out ketchup from a bottle
Newton's third law of motion states that for every action there exist an equal but opposite reaction. Thus, Newton's third law of motion is a law that is generally based on action-reaction force pairs.
In Science, action-reaction force pairs make it possible for;
However, taking out ketchup from a bottle doesn't involve action-reaction force pairs and as such do not apply the third law of motion except.
In conclusion, taking out ketchup from a bottle apply the first law of motion because the ketchup was static (at rest) until an external force acted upon it, thereby causing it to pour out from the bottle.
