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.

  • Q #1: 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.

  • Q #2: Escherichia cell is plated on nutrient agar plates that each contain a different type of antibiotic. The shaded area represents growth of the bacteria. Which of the following plates contains bacteria that were most resistant to the antibiotic

    A. A

    B. B

    C. C

    D. D

    Answer Explanation

    This is the plate with the most growth despite the presence of antibiotic cover.

  • Q #3: A represents atomic mass and 2 represents an atomic number, which of the following describes an atom after a proton is emitted?

    A. A-1,2-1

    B. A-1,2+1

    C. A,2-1

    D. A+1,2-1

    Answer Explanation

    This is because when a proton is emitted from an atom, the atomic mass decreases by one unit, and the atomic number decreases by one unit. The atomic mass is the sum of protons and neutrons in the nucleus, and the atomic number is the number of protons in the nucleus. Therefore, if a proton is lost, both numbers decrease by one.
