What is the first velocity of the car with one washer at
the 0.25 meter mark?
calculate the first and second velocities of the car with
one washer attached to the pulley, using the formulas
vi = 0.25 m/tı, and
u2 = 0.25 m/(t2-ti)
where t, and t2 are the average times the car took to
reach the 0.25 and the 0.50 meter marks. record these
velocities, rounded to two decimal places, in table e.
what is the second velocity of the car with one washer
at the 0.50 meter mark?
m/s

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
