HELP ME Two particles are separated by 0.38 m and have charges of -6.25*10-9 C and
2.91 x 10-9 C. Use Coulomb's law to predict the force between the particles if
the distance is doubled. The equation for Coulomb's law is Fe = kq,92, and
the constant, k, equals 9.00 x 10°Nm2c2

Aprojectile is launched from ground level with an initial velocity of v 0 feet per second. neglecting air resistance, its height in feet t seconds after launch is given by s equals negative 16 t squared plus v 0 t. find the time(s) that the projectile will (a) reach a height of 192 ft and (b) return to the ground when v 0equals112 feet per second. (a) find the time(s) that the projectile will reach a height of 192 ft when v 0equals112 feet per second. select the correct choice below and, if necessary, fill in the answer box to complete your choice.
