1

Changes to an object's speed or direction of motion are caused by which of the following?

72% Answer Correctly

work

a force

kinetic energy

power


Solution

Force is applied to change an object's speed or direction of motion.


2

In cell biology, cytokinesis results in two separate:

57% Answer Correctly

nuclei

chromatids

chromosomes

cells


Solution

During cell division, the cytokinesis phase occurs when cytoplasm and cell membranes complete their separation resulting in two separate cells.


3

"For every action, there is an equal and opposite reaction." This describes which of Newton's laws of motion?

69% Answer Correctly

second

third

fourth

first


Solution

Newton's third law of motion states that For every action, there is an equal and opposite reaction. When an object exerts a force on another object, the second object exerts a force of equal magnitude in the opposite direction on the first object.


4

pH is a scale that measures of how basic or acidic a solution is. A solution with a pH of 9 is:

68% Answer Correctly

neutral

water

acidic

alkaline


Solution

An acid is a substance that gives up positively charged hydrogen ions (H+) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.


5

"The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object." This describes which of Newton's laws of motion?

65% Answer Correctly

second

third

first

fourth


Solution

Newton's second law of motion states that The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object. This law basically means that the greater the mass of an object, the more force is needed to overcome its inertia.
