Oceanographer Bob Ballard, famous for his discovery of the Titanic on the floor of the Atlantic Ocean, used the deep diving submersible Alvin to examine the wreckage for the National Geographic Society. If you used a 1/8 scale model in water at 60oF to evaluate drag characteristics, what model velocity should be used in tests to correspond to a current of 15 knots in liquid water near 32oF

Acar is going 5m/s around a bend with a radius of 10m/s why is the accelerant?

How will the system respond to a temperature increase?

Assume that two of the electrons at the negative terminal have attached themselves to a nearby neutral atom. there is now a negative ion with a charge -2e at this terminal. what are the electric potential and electric potential energy of the negative ion relative to the electron? the electric potential and the electric potential energy are both twice as much. the electric potential is twice as much and the electric potential energy is the same. the electric potential is the same and the electric potential energy is twice as much. the electric potential and the electric potential energy are both the same. the electric potential is the same and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron. the electric potential is twice as much and the electric potential energy is increased by the mass ratio of the oxygen ion to the electron.
