An object carries a +15.5 uC charge. It is 0.525 m from a -7.25 uC charge.
What is the magnitude of the electric
force on the object?
(u stands for micro. Remember, magnitudes
are positive.)

Suppose an objects initial velocity is 10m/s and it’s final velocity is 4 m/s. mass is constant. what can best be concluded about the object based in the work-energy theorem

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
