Two boats- boats A and B are anchored a distance of 18 meters apart . The incoming water waves force the boat to oscillate up and down, making one complete cycle every 20 seconds. When boat A is at its peak, boat B is at its low point and there is a crest in between bthe two boats. Vertical distance between the boats is 12 meters. The wavelength is m, period is ___ s, frequency is ___ Hz, and the amplitude is ___m.

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
