ACTUAL EXAM QUESTIONS WITH CORRECT
VERIFIED ANSWERS/ RATED A+
What are the 4 forces that govern the universe? - ANSWER - Gravity, nuclear,
electromagnetic, Weak Force.
Gravity - ANSWER - acts like glue, holding stars, planets, & galaxies together. It causes
dispersed materials to form, it is responsible for keeping the planets & comets in orbits
around the sun, it is responsible for keeping satellites in orbit, it causes tides, it helps to
control temp., allowing stars to expand when its core temp. increased & increases in
gravitation if the stars core temp. cools too much, is a dynamic process of Earth through
processes like erosion etc.
Nuclear Force - ANSWER - Responsible for binding protons & neutrons in the nucleus.
The residual strong force prevents the repulsion between the protons from pushing the
nucleus apart. Very Strong, strongest of the 4 but has a short range.
Electromagnetic Force - ANSWER - Depends on electrical charge instead of mass,
carried via photons & holds atoms & molecules together. It effects neg. & post. charged
particles. Both men. & electric forces are as a result of photon exchange. Electric force
like charges repel & Magnetic force like & unlike repel.
Weak force - ANSWER - plays a role in nuclear reactions, fusion & fission. Plays a role
in radioactive decay.
Lever - ANSWER - object is pivoted about an axis, the load & effort can be applied on
either or the same side. Load=weight. Effort is the amount that is needed to move the
weight.

,Pulleys - ANSWER - use a wheel & rope to move an object.
inclined plane - ANSWER - plane surface that is placed @ an angle to the horizontal, it’s
easier to move an object up the incline then to move it vertically upwards.
Electro static Phenomena - ANSWER - Comes from the forces that electric charges
exert on each other. The force is between the 2 charges. If they are opposite charges
they ATTRACT, the same charge REPEL. This occurs when there is buildup of a charge
on a surface object, very strong & difficult to separate opposite charges. (static&
electricity from a magnet)
Magnetostatic Phenomena - ANSWER - the study of magnetic fields. charges are either
stationary or in direct current.
Explain Charges or poles - ANSWER - When an object is magnetized, all dipoles
(molecular magnets) become aligned. A magnets pole is a point in a magnet @ which
its magnetic force is concentrated. 2 poles North & SOUTH point to its magnetic pole
(north / south) The 1st law of magnetism states that LIKE poles REPEL & UNLIKE poles
attract.
Class of Luminosity - ANSWER - Roman Numerals I to V
I= supergiant’s greatest raid
II= bright Giants
III= Giants
IV= subgiants
V= Main seq. stars (bigger than the sun)
Simple Model of how fusion in stars produces heavier elements - ANSWER - -when 2
nuclei collide it produces a heavier nucleus.
-The high temp., the harder they will collide, higher the chance of fusion.
-The proton-proton chain (4 hydrogen nuclei combine to produce a helium nucleus)
pg. 2
, 1.) 2 protons fuse together to form a deuterium nucleus (1 proton & 1 neutron), takes
place 2x = 2 set. nuclei.
2.) det. nucleus & proton fuse= helium 3 (2 protons & 1 neutron) takes place 2x
3.) 2 helium 3 nuclei fuse = helium 4 (2 protons & 2 neutrons) 2 excess protons r
released.
Predictable patterns of stars & planets in time & location - ANSWER - -most objects in
the night sky move in predict. patterns due to Earths spin about its axis & it's orbit
around the sun.
- Stars & planets: rise in the East & set in the West, as does the sun.
-The sun only does this in Spring & fall equinoxes.
Moon's Phases - ANSWER - *New Moon>Waxing Crescent>1st Quarter>Waxing
Gibbons>3rd Quarter>Waning Crescent> Back to New Moon.
-The phases are based on its position relative to the Sun as it orbits Earth.
-Each complete cycle takes 29 1/2 days.
-moons appearance changes as it orbits Earth, it's rise & set times also change.
New Moon - ANSWER - -Moon lies close to the sun & so it is hidden by the sun's bright
Light.
-Rises @ 6am & highest @ noon, Sets @ 6pm
Waxing Gibbons - ANSWER - moon is starting to grow
rises @ 3pm, highest @ 9pm, sets @ 3am
