Three-point charges are arranged on a line. Charge q3 = +5.00nC and is at the origin. Charge q2 = -3.00 nC and is at x = 5.00 cm . Charge q1 is at x = 2.50 cm. What is q1 (magnitude and sign) if the net force on q3 is zero?

Arock collection comes from which part of earth?

Apotter's wheel moves uniformly from rest to an angular speed of 0.20 rev/s in 32.0 s. (a) find its angular acceleration in radians per second per second. rad/s2 (b) would doubling the angular acceleration during the given period have doubled final angular speed?

If anyone who can me with this hw? i would really appreciate it
