2. Classify the following bonds as ionic, polar covalent, or nonpolar covalent. When doing this, please know that if it is a metal and a nonmetal, it is always ionic. Polar or not is more of a degree than an exact line. Generally, if the electronegativity is .4 or less, it is nonpolar covalent. (1 points each)

Answer 1

a. When an object falls freely to the ground, it is under the effect of a constant force known as force of gravity. No other forces act on it. Hence, from Newton's second law of motion, we can say that this constant force of gravity accelerates the the freely opposite, their effects do not get cancelled because these action and reaction forces do not act on the body. ball has s ball than a cricket ball moving with the same velocity.

b. Even though the magnitudes of action force and reaction force are equal and their directions are opposite, their effects do not get

cancelled.

c. It is easier to stop a tennis ball as compared to a cricket ball, when

both are travelling with the same velocity.

d. The velocity of an object at rest is considered to be uniform...
