According to the elastic conservation momentum
m1v1 + m2v2 = m1V1 +m2V2
v: velocity before collision, V after collision
<span>the magnitude of the final velocity of the red marble
</span>m1v1 + m2v2 = m1V1 +m2V2
V2 is the final velocity we must find
V2 = 1 / m2 ( m1v1 + m2v2 - m1V1)
= 1/1.2 (3.5x15 + 1.2x 3.5 - 3.5x 5.5)= 63.29 cm/s
Answer: Object B
The velocity of object A is depicted in the graph as a straight line (constant speed therefore no acceleration).
The graph indicates that the velocity of object B increases (the object is accelerating).
It’s either Asia or the America
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 
Yes! Fossils, The outlines of the continents and geological features .
