Why was the weigh/filter paper used in this experiment? check all that apply. -to weigh the tablet -to make sure that all of the broken pieces of tablet were added to the water -to prevent the tablet from absorbing water -to allow for fair comparison of all three trials, with different particle sizes -to avoid experimental error -to ensure that the entire tablet is present, since otherwise it would not dissolve

George is a dalmatian puppy. describe what happens to light that allows you to see george’s black and white coat.

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?

According to the kinetic-molecular theory, what happens to a liquid when it is transferred from one container to another? the volume and the shape stay the same. the volume increases to fill the new container, but the shape stays the same. the volume stays the same, but the shape changes to fit the new container. the volume and the shape change to fill the new container.
