Acar moves at a speed of 50 kilometers/hour. its kinetic energy is 400 joules. if the same car moves at a speed of 100 kilometers/hour, then its kinetic energy will be joules. the braking distance at the faster speed is the braking distance at the slower speed.

Two technicians are discussing a resistance measurement between the can-h and can-l wires. technician a says this measurement should be done with the ignition switch in the "run" position. technician b states that a measurement of 0 ohms indicates an open in the network. which technician is correct?

The focal length of a relaxed human eye is approximately 1.7 cm. when we focus our eyes on a close up object, we can change the refractive power of the eye by about 16 diopters. (a) does the refractive power of our eyes increase or decrease by 16 diopters when we focus closely? explain. (b) calculate the focal length of the eye when we focus closely.
