Answer:

A) Natural sciences

B) Life sciences

C) Ptolemy

D) Tycho Brahe

Explanation:

A) In the hierarchy of the sciences within the different branches of sciences, we have the following order of the sciences

Formal Sciences → Physics, Chemistry → Life Sciences → Social science

Formal Sciences → Physics, Chemistry → Physics, (Astronomy, Geoscience)

According to the theory of the hierarchy by Auguste Comte, scientific disciplines which are further up the hierarchy (disciplines further to the right of the above flow chart) depends on the developments and or discoveries of the disciplines which precedes them (disciplines further to the left of the above flow chart) in the hierarchy of the sciences

Therefore, the natural sciences rely on the methodological apparatus of formal sciences, especially in mathematics

B) The branch of science which is a sub branch of natural sciences, that includes the study of living organisms, including the study of living things, human beings, plants, animals, microorganisms in the fields of biology, anatomy, botany, and zoology respectively is known as life sciences

C) The geocentric model of the universe, which makes the Earth the center of the whole Universe such that the heavenly bodies and the stars revolved round the Earth was proposed by Ptolemy in the 2nd century CE.

D) The Tycho's supernova of 1952, is so called because of his detailed account of the observation of the supernova.

a football player starts from rest and speeds up to a final velocity of 12 m/s. the speeding up takes a total of 6 seconds. what

gizmo_the_mogwai [7]

Answer:

2 m/s²

Explanation:

From the question given above, the following data were obtained:

Initial velocity (u) = 0 m/s

Final velocity (v) = 12 m/s

Time (t) = 6 s

Acceleration (a) =?

The acceleration of the player can be obtained as follow:

v = u + at

12 = 0 + (a × 6)

12 = 6a

Divide both side by 6

a = 12 / 6

a = 2 m/s²

Thus, the acceleration of the player is 2 m/s²

At one point in space, the electric potential energy of a 15 nC charge is 42 μJ . Part A) What is the electric potential at this

Anastasy [175]

Answer:

Part A:

$\rm 2.8\times 10^3\ Volts.$

Part B:

$\rm 5.6\times 10^{-5}\ J.$

Explanation:

Part A:

Potential energy of charge at the given point, $\rm U=42\ \mu J=42\times 10^{-6}\ J.$

Charge, $\rm q=15\ nC = 15\times 10^{-9}\ C.$

The potential energy at a point due to a charge is defined as

$\rm U=qV$ .

where,

V = electric potential at that point.

Therefore,

$\rm V=\dfrac{U}{q}=\dfrac{42\times 10^{-6}}{15\times 10^{-9}}=2.8\times 10^3\ Volts.$

Part B:

Now, if the charge at that point is replaced with $\rm q_1 = 20\ nC = 20\times 10^{-9}\ C.$ , then the electric potential energy at that point is given by

$\rm U=q_1V = 20\times 10^{-9}\times 2.8\times 10^3=5.6\times 10^{-5}\ J.$

If a bar magnet's neutral region is broken into two, what will most likely occur?

sattari [20]

You can think of a magnet as a bundle of tiny magnets, that are jammed together. Each one reinforces the magnetic fields of the others. Each one has a tiny north and south pole. If you cut one in half, the newly cut faces will become the new north or south poles of the smaller pieces.

So the answer is D
