For 1.0 W of electrical input power, a certain loudspeaker produces a sound pressure level of 92 dB at a distance of 1 m from the speaker. When sound is radiated uniformly into a hemisphere, a handy rule is that the sound power level at the source is 8 dB greater than the level at 1 m. For this speaker, the sound power level at the source LW = dB and the sound power W =
W

Apair of 10μf capacitors in a high-power laser are charged to 1.7 kv.a. what charge is stored in each capacitor? b. how much energy is stored in each capacitor?

Choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. choose a realistic problem for which these are the correct freebody diagrams. be sure that the answer that the problem requests is consistent with the diagrams shown. a 1.0 kg block is placed on top of a 2.0 kg block. a horizontal rope pulls the 2.0 kg block across a frictionless floor with a force of 21.0 n. the coefficient between the two blocks is 0.75. does the 1.0 kg block on top slide?
