A-seismograph works by transferring movements of the earth to a graph. (See illustration below.)-↓ ↓ frame transmits Earth's vibrations to wire frame- wire heavy weight rotating paper drum. pen seismogram tracing of vibrations horizontal Earth movements ↓ base set into the ground In-1935-Charles-F. Richter of Cal-Tech developed a-scale for measuring the magnitude of earthquakes. The Richter Scale formula-is-given-hye E MR = 108 10 E where M* is the Richter magnitude of the earthquake. E joules is the energy released-by-the- earthquake, and E =10** joules is the reference energy of a very small, imperceptible- earthquake. (See plot-below.)< a) When the energy of an earthquake is tripled, by how much does the Richter magnitude- increase? b)→In 1906, the San Francisco Bay area suffered severe damage from an earthquake estimated-to- have had a magnitude of 8.3. The largest earthquake magnitude ever measured was 8.9 for an earthquake-in-Japan-in-1933. Determine the ratio of the energy of…

Q.4/ choose true or false: 1. The reluctance of any core is proportional directly with the length of it and inversely with both the permeability and the cross-section area of it. 2. The number of parallel paths in wave windings is equal to twice of the number of poles. 3. In dc machines with same values of Z, N, Ø, the emf for wave winding type is more than emf of lab winding type. 4. If we insert a current in such a conductor subjected to a constant magnetic field, a movement will achieved giving the principle of electric generator.
