The maximum height that is reached by an object thrown or jumped at a certain initial velocity can be calculated through the equation,
2ad = Vf² - Vi²
Vf is zero (0) in this equation because this is the point at the velocity at the maximum height of the object.
Substituting the known values,
2(a)(-16) = 0 - (3.6)²
The value of a from the equation is 0.405 m/s².
<em>Answer: 0.405 m/s²</em>
Answer:
Less than a quarter of Earth's surfaces are dry, ice free lands
The degree is 4678% to pass theough all membranes.
Answer:
the less shielding of electrons
1) Frequency: 
the energy of the photon absorbed must be equal to the ionization enegy of the atom, which is

The energy of a photon is given by

where
is the Planck's constant. By using the energy written above and by re-arranging thsi formula, we can calculate the frequency of the photon:

2) Wavelength: 91.2 nm
The wavelength of the photon can be found from its frequency, by using the following relationship:

where
is the speed of light and f is the frequency. Substituting the frequency, we find
