The table lists the time it takes for an amount of charge to pass through a point in a wire. A 3 column table with 4 rows. The first column is labeled current with entries W, X, Y, Z. The second column is labeled charge in coulombs with entries 18, 10, 15, 12. The last column is labeled time in seconds with entries 4.3, 3.2, 3.3, 3.1. Janelle is exploring the relationship between the brightness of a light bulb and the current that powers it. When applying these currents to the same bulb, the bulb is brighter when the current is greater. Which lists the currents in the order of the bulb brightness they cause from most bright to least bright? W, Y, X, Z Y, W, Z, X W, Y, Z, X X, Z, W, Y

What would the difference of spectral lines emitted by hydrogen gas in distant galaxies which is normally found at a wavelength of 21 cm on earth, be observed at 21.1 centimeters?

Which notation is used to represent an alpha particle? a. b. c. d.

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
