INC1-NATURAL SCIENCE EXAM
QUESTIONS WITH CORRECT ANSWERS
Which of the following statements correctly describe Newton's first law of motion? -
ANSWER-A object at rest will remain at rest unless a nonzero force acts on it.
Which of the following statements is an example of Newton's second law of motion? -
ANSWER-A heavy car requires more force to accelerate than a light car.
A proton and an electron experience the same amount of electrical force. Which particle
accelerates faster? - ANSWER-The electron, because it has a smaller mass.
Which of the following statements correctly describes magnetic force? - ANSWER-The
greatest magnetic force results when charged particles move at right angles to magnetic
field lines.
Which of the following is a role of gravity in the Universe? - ANSWER-Gravity causes
the curvature of light in the universe.
Which of the following correctly explains how gravity affects the universe? - ANSWER-
Gravitational contraction in high-mass stars results in fusion reactions that synthesize
heavier elements like neon and magnesium.
Which of the following explains the similarity between the law of universal gravitation
and Coulomb's law of electrical forces? - ANSWER-Both formulas are examples of the
inverse square law.
What happens to the gravitational force between two objects when the distance
between them is doubled? - ANSWER-It is one fourth as strong-Gravitation force is
inversely proportional to the distance between two objects squared.
Which of the following types of energy is the combined total of the translational,
rotational, vibrational kinetic energy and potential energy of atoms and molecules? -
ANSWER-Thermal energy.
Which statement correctly describes kinetic energy? - ANSWER-The kinetic energy is
greater in a high mass, fast moving object than a low mass, slow moving object.
Which of the following laws is described by the statement "for every action there is an
equal and opposite reaction"? - ANSWER-Newton's third law of motion.
Which of the following statements is an example of Newton's first law of motion? -
ANSWER-A seat belt stopping the forward motion of a passenger.
, Which of the following statements correctly describes the movement of seismic waves?
- ANSWER-Primary waves are longitudinal waves that travel with the greatest speed.
Which of the following correctly describes wave motion? - ANSWER-Longitudinal waves
consist of compressions and rarefactions moving parallel to the wave motion.
How are light waves different than sound waves? - ANSWER-Light waves result from
the acceleration of electrons whereas sound waves result when disturbances cause the
movement of molecules.
Which of the following statements correctly describes the speed of sound? - ANSWER-
Sound moves faster in warm air than cold air.
Whic of the following electromagnetic waves has the shortest wavelength? - ANSWER-
Gamma rays
Which forms of electromagnetic radiation are higher in energy than visible light? -
ANSWER-Gamma Rays, X-rays, and ultraviolet radiation only.
During a thunderstorm, residents of a town see bright flashes of lightning. they hear
claps of thunder several seconds later. Which statement best explains these
observations? - ANSWER-Light waves travel faster than sound waves.
Which form of electromagnetic radiation has the lowest frequency? - ANSWER-Radio
waves.
Which statement best explains why we can use X-rays to make images of structures
inside the body, but we cannot use visible light for this? - ANSWER-X-rays have more
energy than visible light.
Which of the following are applications of gamma rays? - ANSWER-Decreasing
spoilage in foods and killing cancer cells.
Which of the following statements correctly describes sound wave? - ANSWER-High
frequency sound waves cause the eardrum to vibrate rapidly which is interpreted by the
brain as a high pitch.
Which of the following correctly describes ocean waves? - ANSWER-Tsunami waves
travel mainly underwater but increase in height when they reach the shoreline.
Which of the following statements provides an example of reflection of light and sound?
- ANSWER-The distance of a passing car in a rear-view mirror; echoes produced in a
mountain valley.
Which of the following correctly describes wave interference? - ANSWER-Tow
transverse waves in phase combine resulting in greater amplitude.
