1

Meteoroids, meteors and meteorites are categorized based on which of the following?

45% Answer Correctly

their location

their size

their density

their temperature


Solution

Smaller rocks shed by asteroids and comets are called meteoroids. When these rocks reach Earth's atmosphere, they burn up in the mesosphere and become meteors. If a meteor manages to reach the Earth, it is called a meteorite.


2

Generally, an atom has __________ negative electrons orbiting the nucleus as it does positive protons inside.

67% Answer Correctly

fewer

equal numbers of

double the number of

more


Solution

An electron is a subatomic particle that orbits the nucleus of an atom. It carries a negative electric charge. Generally, an atom has the same number of negative electrons orbiting the nucleus as it does positive protons inside.


3

The formula for acceleration is which of the following?

56% Answer Correctly

\(\vec{a} = { \vec{F} \over m }\)

\(\vec{a} = { m \over F }\)

\(\vec{a} = { m \over \vec{F} }\)

\(\vec{a} = \vec{F} m\)


Solution

Newton's second law of motion leads to the formula for acceleration which is a measure of the rate of change of velocity per unit time and, if you solve for positive acceleration, reveals how much net force is needed to overcome an object's mass.  The formula for acceleration is  \(\vec{a} = { \vec{F} \over m }\) or, solving for force,  \(\vec{F} = m\vec{a}\).


4

The ovum and oviduct are part of which bodily system?

88% Answer Correctly

digestive

circulatory

reproductive

nervous


Solution

Approximately every 28 days during female ovulation an egg (ovum) is released from one of the ovaries and travels through the oviduct (fallopian tube) and into the uterus. At the same time, the endometrial lining of the uterus becomes prepared for implantation.


5

What part of the nervous system controls simple reflexes?

54% Answer Correctly

medulla

autonomic

spinal cord

cerebrum


Solution

The spinal cord connects the brain to the body's network of nerves. It carries impulses between all organs and the brain and controls simple reflexes.
