a major flaw in copernicus's model was that it still had

Answers

Answer 1

Answer:

Circular orbits, which were believed to be perfect and uniform, but were later shown to be elliptical by Johannes Kepler. Another flaw was that it relied on the idea of epicycles, which were additional circular orbits used to explain the observed irregularities in the motions of the planets. Despite these flaws, Copernicus's model marked a major step forward in astronomical understanding by proposing a heliocentric model, in which the Earth and other planets revolved around the sun, instead of the Earth being the center of the universe.

Answer 2

Nicolaus Copernicus was a Renaissance-era astronomer and mathematician who is famous for his heliocentric model of the solar system. The Copernican model proposed that the Sun, rather than the Earth, was at the center of the universe, and the planets, including Earth, orbited around it. This model was a significant improvement over the earlier geocentric models that placed Earth at the center of the universe. However, Copernicus's model still had some significant flaws.

One major flaw in Copernicus's model was that it assumed that the planets moved in perfect circles around the Sun. In reality, the orbits of planets are elliptical, meaning they are more like stretched-out circles. Copernicus's model failed to account for this, and as a result, it could not accurately predict the positions of the planets.

Johannes Kepler, a contemporary of Copernicus, recognized this flaw and eventually developed his three laws of planetary motion, which accurately described the elliptical orbits of the planets. Kepler's laws replaced Copernicus's assumption of circular orbits and helped to refine our understanding of the solar system.

Another flaw in Copernicus's model was its inability to explain retrograde motion. Retrograde motion is the apparent backward motion of planets in the sky. Copernicus's model suggested that this motion was caused by the planets moving in circular orbits around the Sun, with Earth sometimes overtaking and passing them. However, this explanation was incomplete and did not account for the complex motions of the planets.

It was not until later when astronomers like Tycho Brahe, Kepler, and Galileo Galilei made more precise observations and developed more accurate models that the flaws in Copernicus's model were fully recognized. Nonetheless, Copernicus's model represented a significant step forward in our understanding of the universe, and it paved the way for the development of more accurate models.

a child rides on a merry-go-round, traveling from location a to location d at a constant speed. what is the direction of the child's average velocity between a and d? take the origin to be the center of the merry-go-round.

Answers

The direction of the child's average velocity between locations A and D on the merry-go-round will be in the direction of the displacement of the child, which is the change in position from location A to location D.

If the child is traveling at a constant speed, the average velocity will be in the same direction as the actual velocity at any given moment. The actual velocity of the child is always tangent to the circular path of the merry-go-round, and so the average velocity will also be tangent to the circular path. This means that the direction of the average velocity will be perpendicular to the line connecting the origin (center of the merry-go-round) to the position of the child.

The direction of the average velocity depends on the direction of the child's movement along the circular path of the merry-go-round.

Our solar system is in the Milky Way galaxy. In another galaxy a planet, P, has a circular orbit equal to that of the Earth's, that is, the orbits have the same radius. The masses of the suns in the two galaxies are Sg and Sp respectively and planet P completes its orbit in half the time it takes the Earth. (i) Show that the mass of the Sun in the Earth's orbit is four times the mass of the sun in Planet P's orbit.
(ii)Show that the period of the planet, P, is given by T = 2₁√ √/GM₂ where Mp is the mass of the planet and r the radius of the orbit​

Answers

(i) If the radius of the orbit of Planet P is equal to that of the Earth's orbit, then the gravitational force acting on Planet P can be expressed as:

F = G * Mp * Sp / r^2

where G is the gravitational constant, Mp is the mass of Planet P, and Sp is the mass of the Sun in Planet P's orbit.

The gravitational force acting on the Earth can be expressed as:

F = G * Me * Sg / r^2

where Me is the mass of the Earth and Sg is the mass of the Sun in the Earth's orbit.

Since the radius is the same for both orbits, we can equate the two expressions for the gravitational force:

G * Me * Sg / r^2 = G * Mp * Sp / r^2

Solving for the ratio of the masses of the Suns, we get:

Sg / Sp = Me / Mp

Since the period of a planet in orbit is given by T = 2π √ (r^3 / (G * M)), and Planet P completes its orbit in half the time it takes the Earth, it follows that:

Tp / Te = 2

where Tp is the period of Planet P and Te is the period of the Earth.

Therefore, Tp = 2 * Te

Substituting the expression for T in terms of r and M, we get:

2 * 2π √ (r^3 / (G * Me)) = 2π √ (r^3 / (G * Mp))

Dividing both sides by 2π, we get:

√ (r^3 / (G * Me)) = √ (r^3 / (G * Mp))

Squaring both sides, we get:

r^3 / (G * Me) = r^3 / (G * Mp)

Solving for the ratio of the masses of the Suns, we get:

Sg / Sp = Me / Mp

Since the mass of the Earth is much smaller than the mass of the Sun, we can approximate Me / Mp as 0, and we get:

Sg / Sp = 0

Therefore,

Sg = 4 * Sp

So, the mass of the Sun in the Earth's orbit is four times the mass of the sun in Planet P's orbit.

(ii) If the period of Planet P is given by T = 2π √ (r^3 / (G * Mp)), then the period can be expressed as:

T = 2π √ (r^3 / (G * Mp)) = 2₁√ √/GM₂

If you change the source of wavelength to a longer wavelength (e.g. 600 nm), the distance between the zero order maximum and the third order maximum will decrease, since the numerator (λ) has increased.

The distance between the zero order maximum and the third order maximum in a diffraction pattern depends on the wavelength of the light and the size of the diffraction grating.

If you change the source wavelength from a shorter wavelength to a longer wavelength, the distance between the zero order maximum and the third order maximum will decrease. This is because the distance between the maxima in a diffraction pattern is inversely proportional to the wavelength of the light.

correct application of fermats theorem to fluid dynamics

Answers

Fermat's theorem, also known as the principle of least time, states that the path taken by light or any other wave between two points is the path that minimizes the time taken. In fluid dynamics, this theorem can be applied to the flow of fluids in pipes or channels.

The basic idea is that the fluid will take the path that minimizes the time it takes for it to travel from one point to another. In other words, the fluid will follow the path of least resistance, where resistance is determined by the fluid's velocity and the diameter of the pipe or channel.

For example, in a fluid flow system with multiple branches or turns, the fluid will tend to follow the path with the smallest diameter or the least amount of resistance, as this will be the quickest path for the fluid to take.

This can be important in designing fluid systems, as it can affect the flow rate, pressure, and energy consumption of the system.

In summary, the correct application of Fermat's theorem to fluid dynamics involves considering the time it takes for a fluid to travel from one point to another and selecting the path that minimizes that time. This can help in optimizing fluid flow systems and improving their efficiency.

a baseball is thrown straight up at a speed of 30.0 m/s. how much time will elapse for the ball to return to the ground?

Answers

The time it takes for the ball to return to the ground is approximately 3.06 seconds.

What is the resistance?

Resistance is the opposition to the flow of an electric current, or the opposition to any change. It is measured in ohms and is denoted by the symbol Ω.

When a baseball is thrown straight up, it follows a parabolic path under the influence of gravity. At the highest point of its trajectory, the baseball momentarily comes to rest before falling back down to the ground. To find the time it takes for the ball to return to the ground, we can use the kinematic equations of motion.

The first step is to determine the initial velocity and the final velocity of the ball at the highest point of its trajectory. At the highest point, the ball momentarily comes to rest, so its final velocity is zero. The initial velocity of the ball is 30.0 m/s (assuming that air resistance is negligible).

The kinematic equation that relates the initial velocity, final velocity, acceleration, and time is:

[tex]\mathrm{v_f = v_i + a \times t}[/tex]

where [tex]\mathrm{v_f}[/tex] is the final velocity, [tex]\mathrm{v_i}[/tex]is the initial velocity, a is the acceleration (due to gravity), and t is the time.

At the highest point of its trajectory, the ball reaches a height of

[tex]\mathrm{h =(v_i)^2 / (2 \times g) }[/tex]

where g is the acceleration due to gravity (9.81 m/s²).

This is the maximum height that the ball reaches, and it takes the ball the same amount of time to reach this height as it does to fall back down to the ground.

Using the initial velocity and acceleration due to gravity, we can calculate the maximum height reached by the ball:

[tex]\mathrm{h =(v_i)^2 / (2 \times g) }[/tex]

= (30.0 m/s)^2 / (2 * 9.81 m/s^2)

= 45.9 m

The time it takes for the ball to reach this height is given by the kinematic equation:

[tex]\mathrm{h = v_i \times t + (1/2) \times a \times t^2}[/tex]

Rearranging and solving for time, we get:

[tex]\mathrm{t = (v_f - v_i) / a = - v_i / a}[/tex]

where the negative sign indicates that we are looking for the time it takes for the ball to return to the ground, which is the time it takes to fall from the maximum height.

Substituting the values, we get:

t = - (30.0 m/s) / (-9.81 m/s²) = 3.06 s

Therefore, the time it takes for the ball to return to the ground is approximately 3.06 seconds.

Unless air resistance favors one item over another, all objects of study to the same rate due to gravity, despite differences in mass. Any two masses, bodies, or particles can be attracted to one another by the force of gravity.

Generally

For a Gizmo Bearing Mass of defined as integers

Say

14N, 80N, 98N

Therefore

For 14N

ω = m×g

14 = m×9.8

m1 = 1.42 kg

For 80N

ω = m×g

80 = m×9.8

m2 = 8.16kg

For 98N

ω = m×g

98 = m × 9.8

m3 = 10Kg

a worker at the top of a 594-m-tall television transmitting tower accidentally drops a heavy tool. if air resistance is negligible, how fast (in m/s) is the tool going just before it hits the ground?

Answers

The tool is going at a speed of 339 m/s just before it hits the ground if air resistance is negligible.

The speed of the falling object just before it will hits the ground can be calculated using the equation of motion:

v = sqrt(2gh),

where by v is the final velocity, g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the tower (594 m).

So, v = sqrt(2 * 9.8 * 594) = sqrt(11,532.8) = 339 m/s.

Therefore, the tool is going at a speed of 339 m/s just before it hits the ground.

an intersection that has signals or signs to assign the right of way is called
a. a registered intersection.
b. an unregistered intersection.
c. a controlled intersection.
d. an uncontrolled intersection.

Answers

A controlled intersection is one that contains signals or signs to designate the right of way.

Describe signal.

An electrostatic or electric current known as a signal is used to transfer information from one device or networks to another. Although it can sometimes take other dimensions, such as current, a signal in electronics frequently consists of a time-varying temperature that is also a electromagnet carrying information.

What characteristics do signals have?

They can be deterministic or random, deterministic or agnostic, continuous or continuous time, both analog and digital, periodic or nonstationary, finite or infinite. They can also be separated into groups based on the causality and symmetry of those groups. An optimum impulse signal is one that is 0 everywhere else but infinitely high at the origin.

my 1956 chevy is currently an automatic but i want to make it a 5 speed manual /can i buy just a clutch pedal awing assembly or do i need to buy combo brake and clutch assembly kit?

Answers

My 1956 chevy is currently an automatic but I want to make it a 5-speed manual, You need to buy a combo brake and clutch assembly kit. This should include the clutch pedal, linkage, and other parts needed to make the conversion.

You need to make sure the engine and transmission are compatible with the new assembly. Depending on the model of the 1956 Chevy, you may also need to purchase a different flywheel, bell housing, and clutch to ensure proper compatibility.  

In addition, you may need to make sure that the cross member and transmission mount are compatible with the new clutch and transmission. You will also need to bleed the clutch housing and lines to ensure that the brakes and clutch are working correctly. Additionally, you will need to make sure the shift linkage is correctly adjusted.

A hot-air balloon is ascending at the rate of 12 m/s and is 65 m above the ground when a package is dropped over the side. (a) How long does the package take to reach the ground? (b) With what speed does it hit the ground?

Answers

a) The package takes 2.45 seconds to reach the ground.

b) It hits the ground with a velocity of -24.1 m/s.

To answer this problem, we'll use the equation of motion for a freely falling object:

[tex]d = v_{0}t + 0.5at^{2}[/tex], where d is the distance fallen, [tex]v_{0}[/tex] is the initial velocity (0 m/s in this case), a is the acceleration due to gravity (-9.8 m/s²), and t is the time elapsed.

We can use this equation to find t:

d = 0.5(-9.8)t²

65 = -4.9t²

t = √(65 / -4.9) = 2.45 s

Using this time, we can find the final velocity:

[tex]v = v_{0} + at[/tex]

v = -9.8 * 2.45

v = -24.1 m/s
