How long is penalties in hockey?

Answer 1

Penalties in Water Polo are called ejections. Ejections last 20 seconds and begin as soon as the player ejected is out of bounds. There is a designated Ejection box that a player must wait in. Ejected players must remain in the ejection box until the referee signals the player back in to play. Other penalties are fouls and 5 meter penalty shots. A foul gives an offensive player a free pass. A 5 meter penalty shot is granted to a offensive player when their opponent stops them from shooting in a unsafe manner. 5 meter penalty shots are similar to a penalty kick in soccer, but are slightly controversial because it is a call made purely on the judgment and opinion of a referee.
