What will resultant motion of the chest be? explain

The net force acting on the chest is 3 Newtons to the right. This is because the force on the left is stronger than the force on the right.

If you need more help, comment below and I'd be happy to assist.

explanation:

i was told this before by a teacher, so yeah

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.
