The geocentric model of the solar system was accepted because it made sense based on observations at the time. The heliocentric model became accepted later thanks to the work of Copernicus and Galileo.
Explanation:The geocentric model of the solar system was accepted by scientists for many years because it appeared to make sense based on the observations at the time. In the geocentric model, Earth was believed to be at the center of the universe, with the planets and the Sun orbiting around it. This model was supported by the apparent motion of the celestial bodies in the sky.
For centuries, people observed that the Sun appeared to rise in the east and set in the west, while the planets seemed to move across the sky in different paths. The geocentric model provided a simple explanation for these observations. Additionally, there was a lack of evidence at the time to support an alternative model.
It was not until the 16th century, with the work of Nicolaus Copernicus and later Galileo Galilei, that the heliocentric model of the solar system started gaining acceptance. The heliocentric model, with the Sun at the center, provided a more accurate explanation for the motion of the planets, as well as other astronomical phenomena. The development of telescopes and advancements in observations also contributed to the acceptance of the heliocentric model.

The geocentric model was accepted for years due to its ability to predict planetary motions and its alignment with religious and philosophical beliefs.
The geocentric model, which positioned Earth at the center of the universe, was accepted by scientists and scholars for many years due to a combination of observational, philosophical, and religious reasons.
Even when Greek astronomers suggested that it was more natural for smaller objects to revolve around larger ones, the Ptolemaic model persisted because it was able to predict planetary motion with reasonable accuracy through complex mechanisms like epicycles and deferents.
The geocentric model was further reinforced by the fact that it was embedded in the teachings of the Church, and the heliocentric idea faced significant resistance due to the societal and theological implications of displacing Earth from the cosmic center.
It was not until the works of astronomers such as Copernicus, Brahe, Kepler, and Galileo provided substantial evidence that the heliocentric model began to gain acceptance over the geocentric model.

a car is moving at 5.82 m/s when it accelerates 2.35m/s^2 for 3.25s. what is its final velocity?
Answer: 13.46 m/s
Explanation:
Initial velocity V1 = 5.82 m/s
acceleration A = 2.35m/s^2
Time taken T = 3.25s
Final velocity V2 = ?
Recall that acceleration is the rate of change of velocity per unit time i.e acceleration = (V2 - V1)/T
2.35m/s^2 = (V2 - 5.82 m/s) / 3.25s
cross multiply
2.35m/s^2 x 3.25s = (V2 - 5.82 m/s)
7.6375m/s = V2 - 5.82 m/s
V2 = 7.6375m/s + 5.82m/s
V2 = 13.46 m/s
Thus, the car final velocity is 13.46 m/s
Answer:
The final velocity is 13.5m/s
Explanation:
a = (v-u)/t
2.35 = (v-5.82) / 3.25
7.6375 = v - 5.82
v = 7.6375 + 5.82
v = 13.5 m/s

O A. Seed C germinates more with more light
O B. Seed C germinates more with less light.
O C. Seed C germinates more with more water.
OD Seed Caerminates more with less water.
Answer:
C. Seed C germinates more with more water.
Explanation:
In this experiment, the seed (seed C) was subjected to certain conditions and the result is what has been presented for us to make an inference.
We observe the following from the information given us:
I. the same seeds were used for the experiment
II. the same heat medium of 24 °C was used for all the seeds
III. different daily amount of water was supplied the seeds - 90 ml, 50 ml and 10 ml
From the experiment, we have this result:
the seed that was watered with 10 ml daily did not sprout anything, the seed that was watered with 50 ml daily yielded 12 sprouts while the seed that was watered with 90 ml daily yielded 16 sprouts
When we consider the amount of water given the seed & the produce of the seed, it is safe to conclude that with increase in daily water, there is increase in the number of sprouts by the seed
Hence, C. Seed C germinates more with more water is the correct answer
The given experiment shows that Seed C's germination is directly proportional to the amount of water it receives. More water results in more sprouts.
Explanation:From the given experiment results, the conclusion can be drawn that Seed C germinates more with more water. This is evident as the seed sprouted 16 times with a daily water method of 90 mL, 12 times with 50 mL, and not at all with 10 mL. So, the amount of sprouts is directly proportional to the amount of water provided, the more the water, the more the sprouts. This supports the option that Seed C germinates more with more water. Also, the heat was kept constant to ensure that it doesn't affect the experiment results.

88 kg fullback moving east with a speed of 5.0 m/s is tackled by a 97 kg opponent running west at
3.0 m/s, and the collision is perfectly inelastic. What is the speed of the players just after the tackle?
A) 149 m/s
B) 23.1 m/s
C) 7.31 m/s
D) 0.81 m/s
The speed of the players just after the collision is (D) 0.81 m/s
Inelastic collision:Given that the mass of the fullback is m = 88kg
mass of the opponent, M = 97 kg
speed of the fullback, u = 5 m/s
speed of the opponent, U = 3 m/s
In an inelastic collision, the two bodies move together at the same speed and the total momentum of the system remains conserved.
Let the final speed be v, then by conserving the momentum we get:
mu - MU = (m + M)v
Since the opponent must be moving in opposite direction to the fullback, therefore his momentum is -MU.
88×5 - 97×3 = (88 +97)v
149 = 185v
v = 0.81 m/s
So both the players move with a speed of 0.81 m/s

In this diagram, the Moon is directly in front of the Earth. What would MOST LIKELY happen if the moon was not directly in front of the Earth? A) There would be a total solar eclipse. B) There would not be a solar eclipse. C) There would be a partial eclipse. D) There would be a lunar eclipse.
Answer: C There would be a partial eclipse.
Explanation:
Partial solar eclipses happen when the Moon comes between the Sun and Earth, but the Moon only partially covers the Sun's disk. When this occurs, the Moon, the Sun and Earth don't align in a perfectly straight line, and the Moon casts only the outer part of its shadow on Earth. This happens when only a portion of the Sun is blocked by the Moon. It occurs when the observer is within the penumbra.

How much work is done by gravity when a pine cone (of mass 50g) falls from the top of a tree, 9 m high?
Answer: 4.41 joules
Explanation:
Given that:
work is done by gravity = ?
Mass of pine cone (m) = 50g
Convert mass in grams to kilograms
Since 1000g = 1kg
50g = (50/1000) = 0.05kg
Height of tree (h) = 9 m
Apply the formula for work,
Work = mass x acceleration due to gravity x height
Acceleration due to gravity has a value of 9.8m/s^2
Work = mgh
Work = 0.05kg x 9.8ms^2 x 9m
Work = 4.41J
Thus, 4.41 joules of work is done by gravity.
Answer:
4.5 J

Calculate the braking distance for a vehicle traveling at 30 mi/h (13.4 m/s) with an acceleration of - 9.0 (m/s)/s while breaking.
Answer:
Braking distance of vehicle is 9.97 m
Explanation:
It is given initial velocity of the vehicle u = 13.4 m/sec
Acceleration of the vehicle [tex]a=-9m/sec^2[/tex]
As the vehicle finally stops so final velocity of the vehicle v = 0 m/sec
We have to find the braking distance s
From third equation of motion
[tex]v^2=u^2+2as[/tex]
[tex]0^2=13.4^2+2\times -9\times s[/tex]
s = 9.97 m
So braking distance of the vehicle is 9.97 m
Two charged particles are separated by a distance of .99m. If the charge on particle one is .00045C and the charge on particle two is .0000032C. What is the amount of force between them?
Answer:
The force between the two charges will be 13.22N.
Explanation:
The force between the two charges is given by Coulombs law which says
[tex]F = k\dfrac{Q_1Q_2}{R^2}.[/tex]
In our case
[tex]Q_1= 0.00045C[/tex],
[tex]Q_2 = 0.0000032C[/tex],
[tex]R = 0.99m[/tex].
therefore,
[tex]F = (9*10^9)\dfrac{(0.00045C)(0.0000032C)}{(0.99m)^2}.[/tex]
[tex]\boxed{F=13.22N}[/tex]
Hence, the force between the two charges will be 13.22N.

It takes 3 minutes to make toast in a 1500 watt toaster. Calculate how much work is done by the toaster.
Answer: 2.7 x 10^5 joules
Explanation:
Given that:
Time taken = 3 minutes
convert time in minutes to seconds
(Since 1 minute = 60 seconds
3 minutes = 3 x 60 = 180 seconds)
Power of toaster = 1500 watt
Work done by the toaster = ?
Recall that power is the rate of work done per unit time
i.e Power = work/time
work = Power x Time
Work = 1500 watt x 180 seconds
Work = 270000J
Place the result in standard form
270000J = 2.7 x 10^5J
Thus, 2.7 x 10^5 joules of work is done by the toaster.
