On earth, you can throw a ball straight up until it reaches a height of 18 meters. If you threw the same ball with the same initial velocity on another planet, it would only reach a height of h meters, which is equal to the day of the month in which you were born, divided by 2. For example, if my birthday is February 19th, my ball would reach a height of 9.5 meters on the second planet. What is the acceleration due to gravity on the second planet?

What part of the ear is names after tools, such as the hammer and the anvil?

Acar of mass 800kg is moving at a speed of 2.2m/s.

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
