Momentum is a measure of how difficult it is for a moving object to stop. Which of the following is the formula for momentum?

60% Answer Correctly

\(\vec{p} = {m \over \vec{v}}\)

none of these

\(\vec{p} = m\vec{v}\)

\(\vec{p} = { \vec{v} \over m}\)


Solution

Momentum is a measure of how difficult it is for a moving object to stop and is calculated by multiplying the object's mass by its velocity:  \(\vec{p} = m\vec{v}\).  Like velocity, momentum is a vector quantity as it expresses force applied in a specific direction.

A person's genotype is their genetic makeup and includes:

82% Answer Correctly

recessive alleles

both dominant and recessive alleles

phenotypes

dominant alleles


Solution

A person's genotype is their genetic makeup and includes both dominant and recessive alleles. Phenotype is how the genes express themselves in physical characteristics.


3

Which of the following is not a characteristic of the Sun?

52% Answer Correctly

formed 2.6 billion years ago

is a yellow dwarf star

is composed of hydrogen and helium

makes up over 99% of the mass of the solar system


Solution

The Sun is a G-type main-sequence star (G2V) but is informally known as a yellow dwarf star. Composed of 73% hydrogen and 25% helium, the hot plasma that makes up the Sun reaches 9,900°F (5,505°C) at the surface. It formed approximately 4.6 billion years ago and makes up 99.86% of the mass in the solar system.


4

50°F is how many °C?

72% Answer Correctly

122

-10

58

10


Solution

The formula to convert from F° to C° is:

\(C° = {5 \over 9} (F° - 32)\)

plugging in our values gives:

\(C° = {5 \over 9} (50 - 32)\)

\(C° = {5 \over 9} (18)\)

\(C° = {90 \over 9}\)

\(C° = 10\)


5

Secondary consumers that also eat producers are known as:

62% Answer Correctly

carnivores

scavengers

omnivores

herbivores


Solution

Secondary consumers (carnivores) subsist mainly on primary consumers. Omnivores are secondary consumers that also eat producers. Examples are rats, fish, and chickens.
