A10 kg body is forced against a horizontal elastic spring compressing it an amount of 0.5 m. when the
body was released, it moves on a horizontal surface a distance of 3 m before coming to rest. the force
constant of the spring is 500 n/m. what is the coefficient of friction between the block and the surface.

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.

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.

Answernewton's second law,says that when a contant force acts on a massive body, it causes it to accelerate
