A 2,000 lb car is traveling at an elevation of 5,000 feet ( = 0.002045 slugs/3) on a concrete surface. If the car is traveling at 70 mph and has a CCDD= 0.4 and AAff=20 2 and an available tractive effort of 255lb, what is the maximum grade that this car could ascend and maintain the 70 mph speed?

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.

the answer is neither ball has a charge.

because if they were both positively charged, they will repel each other.

if they were positively and negatively charged, they will seek.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s
