A train travelling along a straight track starts from rest at point A & accelerates uniformly to 20m/s in 20s. it travels at this speed for 60s, then slows down uniformly to rest in 40s at point C. it starts at rest at C for 30s, then reverses direction, accrlerating uniformly to 10m/s in 10s. it travels at this speed for 30s, then shows down uniformly to rest in 10s when it reaches point B A, plot a graph of the motion of the train
B, use your graph to calculate:
1.the train's displacement from point A when it
reaches point C
2.the train's displacement from point A when
it reaches point B
3,the train's acceleration each time its speed
changes

colorectal cancer may also develop from areas of abnormal cells in the lining of the colon or rectum. this area of abnormal cells is called dysplasia and is more commonly seen in people with certain inflammatory diseases of the bowel such as crohn's disease or ulcerative colitis.

explanation:

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
