So if an elephant is walking at 2.25 milers per hour(1 meter per second), slower then a normal human pace, and has a mass of 13,000 kg what would need to be the approximate momentum of a golf ball that has a mass of .45kg to match it

A) 180 miles per hour

B) 10,837 miles per hour

C) 173,000 miles per hour

D) 387,000 miles per hour

E) 650,000 miles per hour

Is there a point between a 10 nc charge and a 20 nc charge at which the electric field is zero?

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?

Asatellite with an orbital period of exactly 24.0 h is always positioned over the same spot on earth. this is known as a geosynchronous orbit. television,communication, and weather satellites use geosynchronous orbits. at what distance would a satellite have to orbit earth in order to have a geosynchronous orbit?
