Exercise A string has a mass per unit length of 2.50 g. m-1 and is put under
a tension of 25.0 N as it is stretched taut along the x-axis. The free end is attached to a tuning fork that vibrates at 50.0 Hz,
setting up a transverse wave on the string having an amplitude
of 5.00 mm. Determine the speed, angular frequency, period,
and wavelength of the disturbance.​

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
