Teen Hoodlum in his souped-up jalopy is traveling along a deep dip in the road. Suppose Hoodlum weighs 170 lb (as measured when standing at rest on a spring scale). When he passes through the lowest point of the circular-shaped dip, with an effective radius of 50 m, the seat must exert an upward supporting force of 250 lb on him. What is his speed at that point

area of focus

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.
