What is Europa's length of day?

Europa, one of Jupiter's moons, has a synchronous rotation period that matches its orbital period around Jupiter, resulting in a length of day of approximately 3.5 Earth days. This means that it takes about 85.2 hours for Europa to complete one full rotation on its axis. Thus, one day on Europa is significantly longer than an Earth day.

Why do some planet have shorter days then earth?

The length of a planet's day is determined by the speed of it's rotation on it's axis. The faster the rotation, the shorter the day. The slower the rotation, the longer the day. This is affected by many factors such as any moons the planet may have (orbital speed, rotation speed or tide lock, distance and direction of travel of the moons all should be considered), past collisions with other large bodies (planetoids and other planets and their moons), and how the stellar dust and debris were moving and colliding when the planet was formed. Some planets are tide locked to their star and have no rotation and therefore no relative "day". One side faces forever toward the blazing heat of it's star, while the other side faces an eternal frozen night.
