Neil and Gus are having a competition to see who can launch a marble highest in the air using their own spring. Neil has a firm
spring (kNeil = 50.8 N/m), but it can be compressed only a maximum of yNeil, max = 14.0 cm. Gus’s spring is less firm than Neil’s (kGus = 12.7 N/m), but its maximum compression is greater (yGus, max = 27.0 cm). Given that the mass of the marble is 4.5 g and ignoring the effects of air resistance, who can launch the marble the highest and what is the winning height? Assume the marble starts from the same height, in both cases when the springs are at maximum compression.
Postitive ions have more protons than electrons, because protons are positively charged. Electrons have a negative charge, so if there were less protons than electrons the job would be negative. If there were the same amount of both, then the positive and negative charges balance each other out, making a neutral charge.
