1. A un objeto que se mueve, inicialmente, a una velocidad uniforme se le aplica una fuerza en la dirección contraria a su movimiento. Si la magnitud de la fuerza es de -62.7N y la masa del
objeto es de 6.27kg, ¿qué aceleración sufrirá el objeto mientras esta fuerza actúa?

3x + 2x = both people using the same measure of like 5x = x= 25 meters per second. 25ms. it takes them 4 seconds to

B. conditioned response

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.
