Answer:
True
Explanation:
Pyroclastic textures occur when explosive eruptions blast the lava into the air resulting in fragmental, typically glassy material which fall as volcanic ash, lapilli and volcanic bombs.
Answer:
E.
Explanation:
The photovoltaic cell is an electronic device that produces electricity when exposed to light particles. It is commonly known as solar cells.
Solar cells are used to convert sunlight energy into electricity. Solar cells are those non-mechanical devices that help to change solar energy directly into electricity. This process of conversion is known as the photovoltaic effect.
Therefore, option E is correct.
Remark
We have to assume that there are only 3 consecutive integers.
Givens
Let the smallest integer = x
Let the middle integer = x + 1
Let the largest integer = x + 2
Formulas
4(x + 2)^2 - 3x^2 = 41+ 2*(x + 1)^2 Expand the brackets.
Solution
4(x^2 + 4x + 4) - 3x^2 = 41 + 2(x^2 + 2x + 1) Remove the brackets.
4x^2 + 16x + 16 - 3x^2 = 41 + 2x^2 + 4x + 2 Collect like terms on both sides
x^2 + 16x + 16 =2x^2 + 4x + 43 Subtract the left side from the right
0 = 2x^2 - x^2 - 16x + 4x - 16 + 43 Collect like terms.
0 = x^2 - 12x + 27 This factors
(x - 3) * (x - 9) = 0
x - 3 = 0
x = 3 or
x - 9 = 0
x = 9
Therefore numbers can be 3,4,5 or 9,10,11
We need to check both.
First group check.
Group One
4*5^2 - 3*3^2 = 41 + 2*4^2
4*25 - 3*9 = 41 + 2*16
100 - 27 = 41 + 32
73 = 73
Group one is correct.
Group Two
4*11^2 - 3*9^2 = 41 + 2*10^2
484 - 243 = 41 + 200
241 = 241 and the second group checks as well. So thee are two sets of answers.
3,4,5 and 9,10,11 <<<<<< Answer.
Note: You should put this in math.
Answer:
The answer is below
Explanation:
1. Remote sensing Data: for example Radiometers and Photometers
2. GPS measurements : for example Geotagging, Fleet tracking
3. Surveying: for example, Theodolite
4. Aerial Photographs: for example, UAV (Unamanned Aerial Vehicles) or Drones
5. Existing digital data files: for example, Maptitude, Ordnance Survey
6. Analogue Maps: for example: Atlas
The outer planets are the planets placed beyond the asteroid belt - they are also called the "Gas Giants" - they are gaseous (so the correct answer is b) , that is, they are mostly composed of helium and hydrogen. They are: Neptun, Saturn, Uranus and Jupiter
