1. A light Tail train track has been designed to follow the route specified in the diagram below. A rectangular route where the corners are smooth turns with a radius of 75m. A fully loaded train is expected to weight 250 tonnes. 0.5km 0.5km - 10.5km 0.75km 0.4km 2km R=75m 0.5km K€– 0.5km a. The corners of the tracks are banked by 7°. If the trains are expected to turn at a constant speed of 15ms-1, how much lateral force is the track expected to withstand?

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.

not copied too! hope this !
