"Science, the Future, and Reflections on the Course" Please respond to the following:
Identify the main developments in science that you find most fascinating. List at least two (2) topics that you wish you could learn more about and explain why.
Share your opinions on the course, including the topics you enjoyed the most and the least and explain why. Describe the salient manner in which you would use the knowledge learned from this course in your daily life.
Suppose that g = 10 m/s2. A 1 kilogram mass is dropped from rest from a height of 0.5 meter. Find the speed of the mass when it hits the ground
A ballistic pendulum is a device used to measure the speed of abullet. A bullet of mass m is fired at a block of wood (mass M)hanging from a string. The bullet embeds itself in the block, and causes the combined block plus bullet system to swing u..
a block of mass 2kg and another 6kg are connected by massless string over a pulley in a shape of a disk with radius
Algebraic Physics Question: Older railroad tracks in the USA are made of 12 meter long pieces of steel. When the tracks are laid, gaps are left between the sections to prevent buckling when the steel thermally expands. If a track is laid at 16 deg..
Calculate the doppler shift of x rays emitted from shocked silicon in a supernova remnant of the ejected material is moving at 5000 km/sec
A ladder of length L=12 m and mass m=45kg leans against a slick wall (there is not friction among ladder and wall). The ladder's upper end is h=9.3 m above the floor. The coefficient of static friction among the ladder and the floor is μ=0.55.
