The motion of an airplane when the pilot changes the throttle setting of the engine is described by the first law. The motion of a ball falling down through the atmosphere, or a model rocket being launched up into the atmosphere are both examples of Newton's first law.
Answer:
D.Tetrahedral
Explanation:
The central atom has 0 lone pair and 4 bond pairs. Hybridization is sp³. The geometry is tetrahedral which has an angle of 109.5°.
According to VSEPR theory, each molecule arranges itself such that it faces minimum repulsion and the given molecule is of type
.
Therefore the answer will be D.
D.Tetrahedral
Answer:
4 m/s
Explanation:
to find m/s, divide the meters term by the seconds term. 100m/25s = 4m/s
