Two particles, with identical positive charges and separation of 2.55 10-2 m, are released from rest. Immediately after the release, particle 1 has an acceleration vector a1 whose magnitude is 4.65 103 m/s2, while particle 2 has an acceleration vector a2 whose magnitude is 8.55 103 m/s2. Particle 1 has a mass of 6.05 10-6 kg.
a. Find the charge on each particle. q1 = C q2 = C
b. Find the mass of particle 2. kg

An engineer designs a roller coaster so that a car travels horizontally for 162 ft, then climbs 127 ft at an angle of 31.0° above the horizontal. it then moves 127 ft at an angle of 46.0° below the horizontal. if we take the initial horizontal motion of the car to be along the +x-axis, what is the car's displacement? (give the magnitude of your answer, in ft, to at least four significant figures and give the direction of your answer in degrees counterclockwise from the +x-axis.)

An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
