What relationship between the sun and earth did copernicus formulate?

Physics
1 answer:
Dmitrij [34]3 years ago
5 0

Answer:

The astronomical model created and published by Nicholas Copernicus in the year 1543 is called Copernican heliocentrism. The model set the Sun in immobile position near the center of the solar system with Earth, as well as the other planets, spherical, epicycled and at consistent frequencies around it.

A conductor differs from an insulator in that a conductor.
Zina [86]

Answer:

has free electrons

Explanation:

A conductor has free electrons while an insulator does not. Free electrons are electrons which are not bounded tightly to their parent atoms, and are free to move given the right conditions (ie. a strong EM field).

What is the speed of a wave that has a frequency of 6 Hz and a wavelength of 4 m?
notsponge [240]

Answer:

a ) 24 m/s

Explanation:

Given,

Frequency ( f ) = 6 Hz

Wavelength ( λ ) = 4 m

To find : Speed ( v ) = ?

Formula : -

v = f x λ

v

= 4 x 6

= 24 m/s

Therefore, the speed of a wave that has a frequency of 6 Hz and a wavelength of 4 m

is 24 m/s.

Car enthusiasts often lower their cars closer to the ground as a matter of style. James wants to lower his car by replacing all
Alecsey [184]

Answer:

0.05 cm

Explanation:

The compression of the original spring = 12 - 8.55 cm = 3.45 cm = 0.0345 m

By Hooke's law, F = ke

Where F is the applied force, k is the spring constant and e is the extension or compression. In the question, F is the weight of the car.

k = F/e = 1355 × 9.8 / 0.0345 = 384898.55 N/m

This is the spring constant of the original spring. The question mentions that the force constant of the new spring is 5855.00 N/m smaller. Hence, the force constant of the new spring is 384898.55 - 5855 = 379043.55 N/m

With the new spring installed, the compression will be

e = F/k = 1355 × 9.8 / 379043.55 = 0.035 m = 3.5 cm

The difference in the compressions of both springs = 3.5 cm - 3.45 cm = 0.05 cm
