Silica-rich magma traps water and gas bubbles together which causes huge amount of pressure in the magma.
I found this on answers.com, "Silica-rich magma erupts by creating a high viscous magma, which result into releasing high pressurized gases, that cause eruption."
Answer:
Volume of cylinder = 4019.2 cm³
Total volume of container = 8115.2 cm³
Explanation:
Given that :
Height of cylinder, h = 20 cm
Base Radius of cylinder, r = 8cm
Volume of a cylinder, V = πr²h
Volume = 3.14 * 8² * 20
Volume = 3.14 * 64 * 20
V = 4019.2 cm³
The volume of a cube, V = a³ ; where a = edge of the cube
Edge of the cube, a = 16 cm
Hence,
V = a³ = 16³ = 16 * 16 * 16 = 4096 cm³
The total volume of the container is :
Volume of cube + Volume of Cylinder
4019.2 cm³ + 4096 cm³
= 8115.2 cm³
Answer:
Bacteria population In generation n
pₙ = 120 (3ⁿ⁻¹)
Explanation:
The pattern that the bacteria Population follws a geometric series' pattern with the first term equal to the population in the first generation, 120 bacteria, the population in the second generation is the second term and so on.
First term = a = population in the first generation = 120
Second term = a₂ = population in the second generation = 360
Third term = a₃ = population in the third generation = 1080
The general formula for any term of a geometric series is
aₙ = arⁿ⁻¹
a = first term
r = common ratio
But for a geometric series, common ratio is given as the next term divided by the very previous term.
r = (aₙ/aₙ₋₁)
For this question,
r = (360/120) = (1080/360) = 3
So, the right model for the profits for any given year n is
pₙ = 120 × 3ⁿ⁻¹
pₙ = 120 (3ⁿ⁻¹)
Hope this Helps!!!
Germany ceased reparation payments
Germany was hard-hit by the great depression. One major factor was the treaty of Versailles. This treaty was required to settle outstanding disputes following cessation of hostilities in WW1. The allies allowed their desire for revenge to get the better part of them and that the terms dictated to Germany were not necessary debilitating. However, Germany ceased from the huge burden of reparations payments which were required as a condition of the treaty and this caused the spread of the Great Depression around the world.
They receive different amount of force<span />
