If you leave them for a couple of days depending on how hard they are they will eventually ripen, but dont leave them for too long as they will ripen too much but will also turn mouldy and hairy.
if it is still green and has been cut / removed from the plant then it will not ripen the same as it would have if it had ripened on the vine. Strawberries aren't like tomatoes they will not taste good if picked green. Must be red before picking.
Kiwi are small, flightless birds native to New Zealand. They do not ripen. Kiwifruit, on the other hand, will continue to ripen after they are picked.
Vegetables don't ripen after being picked.

Once they get sufficiently big, they can be picked green and ripened off the vine in a dark cool location or make fried green tomatoes, or they can be allowed to turn red and ripen on the vine. The best flavor will be realized when allowed to ripen on the vine.
Store them in a paper bag and they will ripen. Fruit gives of a gas that helps it ripen, it is a very small amount the paper bag helps to concentrate it.
yes it can
Rhubarb is ripe when the stalk is a dark red. If its still mostly green, it's not ready to be picked yet, unless you want it really sour! Actually, there are two types of rhubarb and several varieties of each type. Red rhubarb emerges with a red stalk that is completely red. It's ready to pick whenever you're ready to pick it, and a rhubarb that is constantly harvested will continue to send out new stalks until it gets too cool at night. Green rhubarb emerges green and will never turn completely red, no matter how long you wait. Some varieties will have a reddish base when the stalks get very thick. Both varieties do not get 'sweeter' as the stalks get bigger.
Fruit can ripen slightly after you've picked them, for example if you buy a melon that is still slightly unripe (hard) leave it out for a couple of days and it will become a lot more juicy
