Find the time interval measured by your stationary watch if your friend’s watch measures 1.0 year while she is traveling at 0.999c aboard a futuristic interstellar rocket. SUBJECT: Astronomy Topic:Time Dilution

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
