This is called PARALLAX. Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
A, it's more about the force with leverage.
Answer:
Explanation:
As we know that the motion of the balls with respect to the position of center of mass is pure rotational motion
so here we can find the position of center of mass with respect to ball B as
also we know that the velocity of the center of mass is given as
now relative velocity of ball B with respect to center of mass is given as
now tension in the string is given as
Answer:
Explanation:
The force that one atom exerts on the other is the negative derivative of the potential energy =
F(x) = - ( -C₆ / x⁷) = - (- (-6) C₆ x⁻⁶ ⁻¹) = - 6C₆ /x⁷
when xis negative, F is positive and when x is positive, F is negative. It is therefore and attractive force and F is always directed to the center
