Answer:
0.000064 cubic meters.
Explanation:
Given the following data;
Length of side = 4 centimeters
Conversion:
100 centimeters = 1 meters
4 cm = 4/100 = 0.04 meters
To find the volume of cuboid;
Mathematically, the volume of a cuboid is given by the formula;
Volume of cuboid = length * width * height
However, when all the sides are equal the formula is;
Volume of cuboid = L³
Volume of cuboid = 0.04³
Volume of cuboid = 0.000064 cubic meters.
Explanation:
The high hardness of quartz, seven on the Mohs Scale, makes it harder than most other natural substances. As such it is an excellent abrasive material. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing
Answer:
B.
Explanation:
The water collects in the ocean; it is then evaporated by the sun. After evaporation the water turns into water vapor, it then condenses to form clouds.
Answer:
1.18 mm
Explanation:
The mass of the block is m, so the weight of the block is mg. If the tension in the iron wire is 0.3 mg, then the total tension in the 4 copper wires is 0.7 mg. So the tension in each copper wire is 0.175 mg.
For each wire:
ΔL/L = F / (EA)
where ΔL is the change in length,
L is the initial length,
F is the force,
E is Young's modulus (modulus of elasticity),
and A is the cross sectional area.
The five wires have the same initial length, and stretch by the same amount.
ΔL/L = ΔL/L
F / (EA) = F / (EA)
(0.3 mg) / (2×10¹¹ Pa × π(1.2 mm)²) = (0.175 mg) / (1.2×10¹¹ Pa × πr²)
0.3 / (2 (1.2 mm)²) = 0.175 / (1.2 r²)
0.36 r² = 0.504 mm²
r = 1.18 mm
Answer: Technician A is correct
Explanation:
The intake manifold is the compactment that all fuel and air supply to the cylinders. It's connected to the engine so it has to be disconnected while the exhaust manifold receives all the exhaust gases from the cylinders and releases the gas through a single or double exhaust gases outlet.
