Mindy needs the apparatus to be able to detect a change in area as small as 3.50 cm2 occuring over a time period of 1.50 s. if the minimum emf that can be reliably detected is 2.00 × 10 − 4 v, what is the magnitude of the minimum external magnetic field that would be needed from the solenoid?

In finance, diversification is the process of allocating capital in a way that reduces the exposure to any one particular asset or risk. a common path towards diversification is to reduce risk or volatility by investing in a variety of assets.

Jenny and fred both play a long note on their trombones. a stationary observer hears the sound increasing and decreasing repeatedly in loudness. which of these must be true? the sound waves from the two trombones have slightly different frequencies.the sound waves from the two trombones have the same frequency.the sound waves from the two trombones have slightly different amplitudes.the sound waves from the two trombones have the same wavelength.the sound waves from the two trombones have slightly different velocities.  lolthe answer is          the sound waves from the two trombones have slightly different frequencies.
