1.A 50-gram horizontal conductor carrying 3 Amps of current is suspended motionless by a uniform magnetic field. The conductor is 12 meters long: B (external)⨀⨀⨀⨀⨀ g ?⨀⨀⨀⨀⨀A. From the information above, determine the strength of the magnetic field. (14 mT)B. In which direction is the conventional current traveling? (left)C. If electrons carry this current, which side of the conductor is positively charged?

If one were to put the y value into the equation, they could find out what x is for a certain value of y.  putting in the value of y (1), we get the equation: 1=4x-12=4xx=0.5this means that the value of x when why is 1 is x=0.5

B. that is the answer

To find speed, or mph, use distance/time.

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.
