a platform is attached at point "a"toapypt, and at point "b" by a cable to a wall to the right. a mass of m-5.00kg sits on the platform the platform has a mass of 2.70 kg. ands1.50 m long the c. o.m of the plank is 0.500m from the pivot. the 5.00 kg mass is 1.00m from the pivot the cable is atached 1.250m from the pivot. wall 3ートバ30.0 to r" to do. a. create the equations for the sum of all the forces in the x, and y directions, and the sum of all torques, using the values given in the problem b. calculate the tension in the cable, and the x and y forces at “a”

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

kepler used the data from tycho blahe (his mentor) to construct the laws of planetary motion.
