Un resorte ligero, con constante de fuerza 3.85N/m, se comprime 8.00 cm mientras se mantiene entre un bloque de 0.250 kg a la izquierda y un bloque de 0.500 kg a la derecha, ambos en reposo sobre una superficie horizontal. El resorte ejerce una fuerza en cada bloque, y tiende a separarlos. Los bloques se sueltan simultáneamente desde el reposo. Encuentre la aceleración con la que cada bloque comienza a moverse, dado que el coeficiente de fricción cinética entre cada bloque y la superficie es:

Aplanet of mass m 6.75 x 1024 kg is orbiting in a circular path a star of mass m 2.75 x 1029 kg. the radius of the orbit is r 8.05 x107 km. what is the orbital period (in earth days) of the planet tplanet?

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
