The formula for acceleration is which of the following?
\(\vec{a} = { \vec{F} \over m }\) |
|
\(\vec{a} = { m \over F }\) |
|
\(\vec{a} = \vec{F} m\) |
|
\(\vec{a} = { m \over \vec{F} }\) |
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, \(\vec{F} = m\vec{a}\).
Reproductive haploids are also known as:
ovum |
|
sperm |
|
diploids |
|
gametes |
Reproductive (haploid) cells known as gametes have half as many (23) pairs of chromosomes as normal (diploid) cells. When the male gamete (sperm) combines with the female gamete (ovum) through meiosis to form a zygote, each gamete supplies half the chromosomes needed to form the normal diploid cells.
The energy posessed by a ball on the window ledge of a tall building is an example of what kind of energy?
kinetic |
|
gravitational |
|
potential |
|
inherent |
Kinetic energy is the energy posessed by a moving object. Potential energy is stored energy in a stationary object based on its location, position, shape, or state.
A person's genotype is their genetic makeup and includes:
dominant alleles |
|
phenotypes |
|
both dominant and recessive alleles |
|
recessive alleles |
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.

central |
|
somatic |
|
peripheral |
|
autonomic |
Part of the peripheral nervous system, the autonomic nervous system regulates involuntary activity in the heart, stomach, and intestines.
