Use the table below to answer the question   Object Mass Time of Fall A 5.0g 2.0 sec B 5.0g 1.0 sec C 30.g 0.5 sec D 35.0g 1.5 sec   Which of the following conclusions is supported by the data?

A. Object A and B fall at the same rate

B. The time of fall is independent of the mass of the object

C. The greater the mass of an object, the faster it will fall

D. Air resistance is greater for A than for B

Answer Explanation:

Objects A and B have the same and are subjected to the same gravitational pull. However, object B falls faster than A. This is due to a greater air resistance for A than B.

Therefore, the Correct Answer is D.

    A chlorine molecule contains the fewest covalent bonds among the options provided. It consists of two chlorine atoms bonded together by a single covalent bond. Compared with the other options, ammonia has three covalent bonds, methane has 4 while water has 2.

     

  • Q #2: Which of the following body systems breaks down proteins into amino acids?

    A. Digestive

    B. Excretory

    C. Circulatory

    D. Endocrine

    Answer Explanation

    The digestive system breaks down complex food substances into small and less complex absorbable compounds. Proteins, for instance, are broken down to constituent amino acids through a digestion process that combines mastication and enzymatic breakdown.

  • Q #3: Which of the following characteristics of water helps explain why coastal areas experience less dramatic temperature changes during the day?

    A. Water has a high specific heat capacity

    B. Water is a versatile solvent

    C. Water forms covalent bonds with other water molecules

    D. Water's adhesive properties prevent evaporation

    Answer Explanation

    Water has a high specific heat capacity, which means it can absorb and store a large amount of heat energy without significantly changing in temperature. This helps moderate the temperature fluctuations of the air near the coast, as water can store heat during the day and release it at night, or vice versa.
