Answer:
The outcome of adding 999mm to 100m is 101m.
Explanation:
That's my belief.
Answer: SG = 2.67
The specific gravity for the sand is 2.67
Explanation:
Specific gravity is determined by the formula: density of the substance/density of water
Provided information;
Mass of sand m = 100g
The volume of sand equals the volume of water it displaces
Vs = 537.5cm^3 - 500 cm^3
Vs = 37.5cm^3
Calculating density of sand = m/Vs = 100g/37.5 cm^3
Ds = 2.67g/cm^3
Density of water Dw = 1.00 g/cm^3
Thus, the specific gravity of the sand can be expressed as
SG = Ds/Dw
SG = (2.67g/cm^3)/(1.00g/cm^3)
SG = 2.67
The specific gravity of the sand stands at 2.67
Answer:
Distance: 4.6 km Displacement= -0.2 km
Explanation:
The overall distance covered: 1.5 + 2.4 + 0.7 = 4.6 km
Displacement calculation: 1.5 - 2.4 + 0.7 = -0.2 km
The displacement could also simply be stated as 0.2 km depending on whether negative value is preferred.
