Professional baseball pitchers deliver pitches that can reach the blazing speed of 100 mph (miles per hour). a local team has drafted an up-and-coming, left-handed pitcher who can consistently pitch at 43.35 m/s (97.00 mph) . assuming a pitched ball has a mass of 0.1422 kg and has this speed just before a batter makes contact with it, how much kinetic energy does the ball have?

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 !

h o h o hope you have a merry christmas!

conservation of mass

mass before something happens = mass afterwards
