Explanation:The tetrahedral shape is formed by the electrons repulsing one another, which forms the tetrahedron—the shape in which all the electrons are as far away from one another as possible.
Examples include methane (CH4) and ammonium(NH4+).
Methane has a central carbon atom ringed by four hydrogens, which form the "spokes" of the tetrahedral molecule.
Tetrahedral molecules are nonpolar if the four surrounding atoms are the same, in the cases of methane and ammonium, and have a bond angle of 109.5˚.
However, tetrahedral molecules can also be polar if they are like chloroform (CHCl3). The central atom has four electron domains, but they are differently sized.

Answer:
D. Some of the energy went into the ball, and some of it went into the air.
Explanation:
When Jeanie's mallet hit the ball, some of its energy was transferred to the ball, since the ball moved. The loud noise means that some of the energy was changed into sound. Some of the energy stayed in the mallet, because the mallet did not stop moving when it hit the ball. So, some of the energy went into the ball, and some of it went into the air.
