I thinks it’s 2...........
The process of splitting one large nucleus into
smaller ones is nuclear fission.
The process of combining two small nuclei into
one larger one is nuclear fusion.

Answer:
The two skaters will move with a common speed of 1.19 m/s.
Explanation:
Given that,
Mass of Alex, ![m_1=90\ kg](https://tex.z-dn.net/?f=m_1%3D90%5C%20kg)
Initial velocity of Alex, ![u_1=1.5i\ m/s](https://tex.z-dn.net/?f=u_1%3D1.5i%5C%20m%2Fs)
Mass of Barbara, ![m_2=57\ kg](https://tex.z-dn.net/?f=m_2%3D57%5C%20kg)
Initial velocity of Barbara, ![u_2=2j\ m/s](https://tex.z-dn.net/?f=u_2%3D2j%5C%20m%2Fs)
After the collision, the two skaters move together at a common velocity. Let V is the common velocity. Using the conservation of momentum as :
![m_1u_1+m_2u_2=(m_1+m_2)V\\\\90\times 1.5i+57\times 2j=(90+57)V\\\\V=\dfrac{135i+114j}{147}\\\\V=\dfrac{135i}{147}+\dfrac{114j}{147}\\\\V=(0.91i+0.77j)\ m/s](https://tex.z-dn.net/?f=m_1u_1%2Bm_2u_2%3D%28m_1%2Bm_2%29V%5C%5C%5C%5C90%5Ctimes%201.5i%2B57%5Ctimes%202j%3D%2890%2B57%29V%5C%5C%5C%5CV%3D%5Cdfrac%7B135i%2B114j%7D%7B147%7D%5C%5C%5C%5CV%3D%5Cdfrac%7B135i%7D%7B147%7D%2B%5Cdfrac%7B114j%7D%7B147%7D%5C%5C%5C%5CV%3D%280.91i%2B0.77j%29%5C%20m%2Fs)
Magnitude of final velocity:
![|V|=\sqrt{0.91^2+0.77^2} \\\\|V|=1.19\ m/s](https://tex.z-dn.net/?f=%7CV%7C%3D%5Csqrt%7B0.91%5E2%2B0.77%5E2%7D%20%5C%5C%5C%5C%7CV%7C%3D1.19%5C%20m%2Fs)
So, the two skaters will move with a common speed of 1.19 m/s.
A 2 µC charge q1 and a 2 µC charge q2 are 0.3 m from the x-axis. A 4 µC charge q3 is 0.4 m from the y-axis. The distances d13 and d23 are 0.5 m. Find the magnitude and direction of the resulting vector R. Round your answer to the nearest tenth.
The magnitude is 0.5 N.
The direction is °.0
