The drag force: - Answer 1. increases in magnitude as the object's speed increases 2. is opposite in direction to the velocity of the object v⃗→ Ball A with diameter d and ball B with diameter 2d are dropped from the same height. When the two balls have the same speed, what is the ratio of the drag force on ball A to the drag force on ball B? - Answer Ball A=1/2CdpAv^2 Ball B=1/2CdpAv^2 Ratio Ball A to Ball B: 1/2Cdp(d)v^2/(pv((2d)^2)/n)=1/2*1/2=0.250 A falling object will re...

Two spheres, fastened to "pucks", are riding on a frictionless airtrack. Sphere 1 is charged with 3 nC, and sphere 2 is charged with 15 nC. Both objects have the same mass. 1 nC is equal to 1 × 10−9 C. As they repel, 1. sphere 1 accelerates 5 times as fast as sphere 2. 2. sphere 2 accelerates 5 times as fast as sphere 1. 3. they have the same magnitude of acceleration. 4. sphere 2 accelerates 25 times as fast as sphere 1. 5. sphere 1 accelerates 25 times as fast as sphere 2. 6...
