Seems like the law is nowhere near life for rape (without causing death), so assume much less for the other offenses. Most common is under a year (this is a bit old)

The law:
Before 1997, the definition of rape was: "
Whoever compels a woman to have extramarital intercourse with him, or with a third person, by force or the threat of present danger to life or limb, shall be punished by not less than two years’ imprisonment."
[17]
In 1997, a broader definition was adopted with the 13th criminal amendment, section 177–179, which deals with sexual abuse.
[5] Rape is generally reported to the police, although it is also allowed to report to the prosecutor or District Court.
[9]
The current law reads:
[18]
Section 177
Sexual assault by use of force or threats; rape
1) Whosoever coerces another person
1. by force;
2. by threat of imminent danger to life or limb; or
3. by exploiting a situation in which the victim is unprotected and at the mercy of the offender,
to suffer sexual acts by the offender or a third person on their own person or to engage actively in sexual activity with the offender or a third person, shall be liable to imprisonment of not less than one year.
(2) In especially serious cases the penalty shall be imprisonment of not less than two years. An especially serious case typically occurs if
1. the offender performs sexual intercourse with the victim or performs similar sexual acts with the victim, or allows them to be performed on himself by the victim, especially if they degrade the victim or if they entail penetration of the body (rape); or
2. the offence is committed jointly by more than one person.
Subsections (3), (4) and (5) provide additional stipulations on sentencing depending on aggravating or mitigating circumstances.
Section 178 provides that "
If the offender through sexual assault or rape (section 177) causes the death of the victim at least by gross negligence the penalty shall be imprisonment for life or not less than ten years."
