The student concluded that the current in the LDR is inversely proportional to the potential difference across the LDR. Explain why the student's conclusion is incorrect.

Which equation best describes the law of conservation of momentum?

A mover uses a ramp to push a stereo into the van. The ramp is 3 meters long and 1.5 meters high. What is the ideal mechanical advantage of this ramp?

An airplane travels southwest a distance of 650 km at a velocity of 430 km/h. How long does the trip take in hours?

What is the correct calculation for resistance when the current is 4 amps and the voltage is 24 volts? a) 24 volts - 4 amps = 20 ohms b) 24 volts + 4 amps = 28 ohms c) 24 volts * 4 amps = 96 ohms d) 24 volts : 4 amps = 6 ohms

Blocks A (mass 2.00 kg) and B (mass 10.00 kg, to the right of A) move on a frictionless, horizontal surface. Initially, block B is moving to the left at 0.500 m/s and block A is moving to the right at 2.00 m/s.
