Strontium-90 has a half life of 29 years. If a site held 2000 kg of this isotope, approximately what mass of Strontium-90 would be left after 116 years?

cuz he is really really short, assuming an unorthodox and inherently unlucky configuration of elevator buttons…

explanation:

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."

can you give me more to work here with plzs and you
