Athermometer has its stem marked in millimeters instead of degree celsius. the lower fixed point is 30mm, and the upper fixed point is 180mm. calculate the temperature im degree celsius when the thermometer reads 45mm.

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.)
