Consult Multiple-Concept Example 6 for background on how to approach this problem. In the absence of a nearby metal object, the two inductances (LA and LB) in a heterodyne metal detector are the same, and the resonant frequencies of the two oscillator circuits have the same value of 630.0 kHz. When the search coil (inductor B) is brought near a buried metal object, a beat frequency of 7.30 kHz is heard. By what percentage does the buried object increase the inductance of the search coi
Two balls have their centers 3.0 m apart. One ball has a mass of 2.7 kg. The other has a mass of 4.5 kg. What is the gravitational force between them Assume G = 6.67 × 10 -1N·m /kg 2 a. 1.3 x 10 -11N -11 b. 9.0 x 10 N c. 2.7 x 10 -10N -10 d. 9.0 x 10 N According to Kepler's laws, an imaginary line from the Sun to a planet __________. a. sweeps out equal areas in equal time periods b. sweeps out larger areas the greater the planet's distance from the Sun than it would in the same time interval when closest to the Sun c. sweeps out smaller areas when the planet is closest to the Sun than it would in the same time interval when farthest from the Sun d. remains a constant length through the entire orbit of that planet According to Newt
