Kepler's Laws of Planetary MotionThe three laws of planetary motion as formulated by Kepler are: Kepler's first law: Each planet moves around the sun in an elliptical orbit with sun located at a foci of the ellipse. Kepler's second law: The areal velocity of the planet around the sun...
Why does current flow opposite to the direction of motion of electrons? Why can sine and cos functions be used interchangeably in wave motion? Why the mesaure of the sphere doesn't play a part at the pendulum??? Why doesn't the force of gravity change the speed of a bowling ba...
Pandas - Extrapolate dataframe rows, I extrapolate on rows, not columns, so I always have at least two values. The linear interpolation from df.interpolation(method = 'linear', direction = 'forward', direction_limits = 'both') gives a slope of 0 when extrapolating....
Consider an atom of atomic number Z. The nucleus on its nucleus is +Ze . Let an electron of mass m and charge '-e' revolve round the nucleus in a circular orbit. Let an Let v be its velocity . The coulomb's electrostatic force of attraction between
Known that the angular momentum is conserved along the motion, but I am confused about how to relate the variables, i.e. r and v. I have tried to derive R and tried to put into the equation of angular momentum but the formula seems make it more complicated as it introduce one more ...
The main impact of vegetation on incident waves is exerting an additional force on water motion [21,22]. This force can be described by the Morison equation, which is composed by drag force (FD) and inertia force (FM) [23]. For normal field conditions, the drag force is the dominant ...
