A gnat takes off from one end of a pencil and flies around erratically for 21.6 s before landing on the other end of the same pencil. If the gnat flew a total distance of 8.65 m, and the pencil is 0.0863 m long, find the gnat's average speed and the magnitude of the gnat's average velocity.

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct

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.)

Give me a example of a decomposer. explain what would happen if decomposers were absent from a forest ecosystem
