Answer:
C
Explanation:
During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom.
To calculate that, we'd need to know the coefficient of static friction between the block and the surface, which you haven't told us.

That gives you the magnitude of velocity, but it doesn't handle
the directions that are involved.
Explanation:
Introduction to the quantum mechanical model of the atom: Thinking about electrons as probabilistic matter waves using the de Broglie wavelength, the Schrödinger equation, and the Heisenberg uncertainty principle. Electron spin and the Stern-Gerlach experiment.
