The entire premises of this question infers to the concept of Creation. So the reason why the universe was created, in that sense, was so god could create a land to support the civilization he wanted.
Here are the parts of the comet:
1. NUCLEUS: This is the frozen part of the comet. It is also known as the core. It is made up of ice and dust which are completely covered by organic matter. The nucleus usually consist of frozen water but other materials that are in frozen forms can be found in it. Comet nuclei are usually less than 16 kilometer in diameter.
2. COMA: The atmosphere of dust and gases formed when the nucleus vaporize. The coma refers to the envelope of gases that surround the comet's nucleus. The coma plus the nucleus forms the head of the comet. The coma is about a million kilometer in diameter and is made up of gases and dust which sublime from the comet's nucleus.
3. ION TAIL: Tail made of ions that appear to point away from the comet's orbit. The charged solar particles convert the gases found in the comet to ions thus forming an ion tail. The ion tail can measure over 100 million kilometer long and it accelerate much faster than the dust tail.
4. DUST TAIL: Tail made up of small solid dust particles. It is formed by radiation from the sun, which forces dust particles away from the coma. It usually point away from the sun because the tail are shaped by the solar wind. As the distance from the sun increases, the dust tail usually become faint and diminished.
Answer:
D. 0.1
Explanation:
Using transformer equation,
N2/N1 = I1/I2................... Equation 1
Where N2 = secondary coil, N1 = primary coil, I1 = input current, I2 = output current.
make I2 the subject of the equation
I2 = I1/(N2/N1)............ Equation 2
From equation 2 above, For the output current of the secondary coil to be 10 times the input current, N2/N1 = 0.1
Hence the right option is D. 0.1
Answers:
A) 0.204 m
B) 0.285 s
Explanation:
<h2>Answer A:</h2>
This described situation is free fall, this means the initial velocity of the fly is zero, and the equation that will be used is:
(1)
Where:
is the final height of the fly
is the initial height of the fly
is the initial velocity of the fly
is the time
is the acceleration due to gravity
(2)
(3) This is the distance at which the fly would begin to beat its wings
<h2>Answer B:</h2>
In this part we will also use equation (1), but we will find the time:
(1)
Where:
is the final height of the fly
is the initial height of the fly
is the initial velocity of the fly
is the time we need to find
is the acceleration due to gravity
(4)
Isolating :
(5)
(6) This is the time it would take for a fly to hit the bottom of the box
