Answer:
Kepler's laws apply: First Law: Planetary orbits are elliptical with the sun at a focus. Second Law: The radius vector from the sun to a planet sweeps equal areas in equal times. Third Law: The ratio of the square of the period of revolution and the cube of the ellipse semimajor axis is the same for all planets.
Answer:
8m/s^2
Explanation:
<em>Acceleration</em><em>=</em><em>initial </em><em>velocity</em><em>-final </em><em>velocity</em><em>/</em><em>time</em>
<em>initial</em><em> </em><em>velocity(</em><em>u)</em><em> </em><em>is </em><em>3</em><em>2</em><em> </em><em>final </em><em>velocity</em><em> (</em><em>v)</em><em> </em><em>is </em><em>9</em><em>6</em>
<em>therefore</em>
<em>a=</em><em>9</em><em>6</em><em>-</em><em>3</em><em>2</em><em>/</em><em>8</em>
<em>a=</em><em>8</em><em>m</em><em>/</em><em>s </em><em>squared</em>

Answer:
Speed Unchanged.
Explanation:
As work is defined as a product of force over a distance. If the distance in altitude is constant = 500km, there's 0 change in distance and force, no work would be done by the gravitational force.
Since potential energy of the satellite is unchanged, unless there's additional internal energy source, the kinetic energy would remain unchanged, so would its speed.
Answer:
Explanation:
Rydberg's formula is used to describe the wavelengths of the spectral lines of chemical elements similar to hydrogen, that is, with only one electron being affected by the effective nuclear charge. In this formula we can find the rydberg constant, knowing the wavelength emitted in the transcision between two energy states, we can have a value of the constant.
Where it is the wavelength of the light emitted, R is the Rydberg constant, Z is the atomic number of the element and are the states where .
In this case we have Z=1 for hydrogen, solving for R:
This value is quite close to the theoretical value of the constant
Distance = rate * time, so 35000 = 2r or the average speed of the rocket would 17500 miles per hour or 17500 mph
