By conservation of momentum,
(900 kg) (15.0 m/s) i + (750 kg) (20.0 m/s) j = (900 kg + 750 kg) v
where v is the velocity vector of the combined cars. Solve for v :
(13,500 i + 15,000 j) kg•m/s = (1650 kg) v
v ≈ (8.18 i + 9.09 j) m/s
Then the direction of v relative to East is θ such that
tan(θ) ≈ 9.09/8.18 ⇒ θ ≈ 48.0°
so the wreckages would move at approximately 48.0° north of east.

None
Explanation:
Every month, the lining of the uterus becomes thicker in preparation for an egg that has been fertilized to place itself there. In the event that this transpires, hormones originating from the reproductive organs will stabilize the vascular tissue of the endometrium, which in turn will offer a setting for the embryo to grow in.
This is further explained below.
<h3>What is the uterine wall?</h3>
Generally, The uterine lining grows every month in anticipation of the implantation of a fertilized ovum. When this happens, the endometrium's vascular tissue is stabilized by hormones from the reproductive organs, providing an environment for the growing fetus.
In conclusion, There are three distinct layers of muscle tissue that compose the uterine wall. The muscle fibers are intertwined with the connective tissue of blood vessels, elastic fibers, and collagen fibers, and they may run in either of three directions: longitudinally, circularly, and obliquely. As the baby grows within the uterus, this thick muscular wall begins to stretch out and eventually becomes much thinner.

The answer is: C. both a and b
Midlife transition typically happen between the age of 35 -45. During this period, people would often conduct a self-examination on whether they are fulfilling their true potential in their life. If they believe they don't, then they would most likely experience a midlife crisis and started to seek various excitement to cope with the desperation.
