Wavelengths of light are emitted when an electron is coming from an energized state back to its initial state. The energy that is omitted comes in the form of the wavelength. I'm not completely sure if this is totally the way to say it, but it is what I remember from chem last year.
Answer:
where m < M is delivered to the space station. Soon after, the space station's orbit is adjusted so that it is 50 km ...
The initial velocity used by the flea to jump straight upward is 3.1 m/s
<h3>Data obtained from the question</h3>
The following data were obtained from the question:
- Acceleration due to gravity (g) = 9.8 m/s²
- Maximum height (h) = 0.49 m
- Final velocity (v) = 0 m/s (at maximum height)
- Initial velocity (u) =?
<h3>How to determine the initial velocity</h3>
The initial velocity used by the flea to jump upward can be obtained as follow:
v² = u² – 2gh (since the ball is going against gravity)
0² = u² – (2 × 9.8 × 0.49)
0 = u² – 9.604
Collect like terms
u² = 0 + 9.604
u² = 9.604
Take the square root of both sides
u = √9.604
u = 3.1 m/s
Thus, the initial velocity is 3.1 m/s
