In the figure particle 1 of charge -4.20q and particle 2 of charge +1.30q are held at separation L = 5.30 m on an x axis. If particle 3 of unknown charge q3 is to be located such that the net electrostatic force on it from particles 1 and 2 is zero, what must be the (a) x and (b) y coordinates of particle 3? (a) Number i Units (b) Number i ! Units

A ball of mass m traveling at a speed of 0.80c has a perfectly inelastic collision with an identical ball at rest. If Newtonian physics were correct for these speeds, momentum conservation would tell us that a ball of mass 2m departs the collision with a speed of 0.40c. Let's do a relativistic collision analysis to determine the mass and speed of the ball after the collision.

Pls help ASAP

what are the i and j called in physics that have the arrow above them that resemble a triangle?

hat number w.ww The word "units" refers to the corresponding quantity of something. For example, 2 is a number; 2 seconds is a physical quantity that has the units of second. In physics problems, are usually not looking for a number; we are looking for a need to also know the units. If you do not include units with the answer, you will not receive physical quantity, which means we full credit. Physicists are very nitpicky about this! 8. You may have learned the formula distance speed x time. How long would it take in seconds to travel a distance of 2000 meters if you are traveling at a speed of 25 meters per second?

A child walking in a field makes three consecutive displacements. The child first moves 6.25 m westward, then 12.9 m northward. Finally, the child moves back to the starting point of the first displacement. What is the magnitude and direction of the child's third displacement? Give the magnitude in m and the direction as an angle south of east. magnitude 14.33 v m direction 115.18 Use trigonometric functions, along with the components of the vector sum, to find the angle. Check the direction against your diagram.° south of east Additional Matoriale

It's saying that is not correct. I don't want to practice this concept incorrectly. Thank you for your help.
