John weighs 725 N and is sitting at the top of the Tower of Terror, 60 m above the ground, by what factor will his gravitational potential energy change when he drops to 20 mo? A. one-third
B. 2×
c. one-half

A. one-third

Because th height is directly proportional to the potential energy. So, when its height is reduced one - third (from 60m to 20m), then its potential energy will also be reduced to one-third.

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
