The model below shows an atom of an element. 10 light gray and 8 dark gray balls sit at the center with 2 concentric black rings around them. The inner ring has 2 medium gray balls on it, and the outer ring has 6 medium gray balls on it. At bottom, a dark gray ball = +1, a light gray ball = 0, a medium gray ball = negative 1.

What is the atomic number of this atom?

6
8
9
16

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?

Agraduated cylinder contains 63.0 ml of water. a piece of gold, which has a density of 19.3 g/ cm3, is added to the water and the volume goes up to 64.5 ml. calculate the mass in grams of the gold that was added to the water. explain how you got your answer.

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
