Explanation:
Answer:
The speed of the turtle is 9.41 centimeters per second.
Explanation:
Speed of small turtle = 566 furlong/fortnight
1 furlong = 20,116.8 cm
1 fortnight = 1,209,600 seconds
Speed of small turtle in centimeter per seconds:
The speed of the turtle is 9.41 centimeters per second.

Answer:
In addition to aluminium, the main materials in duralumin are copper, manganese and magnesium.
Answer:
V₂ = 15.3
Explanation:
Given data:
Initial volume = 12.0 L
Initial temperature = 20°C
Final temperature =100°C
Final volume = ?
Solution:
First of all we will convert the temperature into kelvin.
20°C + 273 = 293 K
100°C + 273 = 373 K
Formula:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 12.0 L × 373 K / 293 k
V₂ = 4476 L.K /293 k
V₂ = 15.3
V₂ = 1566 L.K / 298 K
V₂ = 5.3 L
Substances that have a define size and shape and vibrating particles that are close together are called Solid.
Explanation:
There are three states of matter - solid, liquid and gas.
Lets talk about solid state in detail.
In solid particles are closely packed and so they have very less or no space to move which results in vibrating particles. This results in solid substances having a fixed shape and volume.
The particles have very little space in between them, so it is not easy to compress solid.
There is no free space for particles to slide over each other, which does not allow solids to flow.
Also, particles in solid have a regular arrangement, they are not randomly packed.
