Which of the following is the formula for work?
\(W = \vec{F}\vec{d}\) |
|
\(W = {F}{d}\) |
|
\(W = {{F}\over{d}}\) |
|
\(W = {\vec{F} \over \vec{d} }\) |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
An asteroid belt holds many of the asteroids in our solar system. It is located between the orbits of which planets?
Mercury and Venus |
|
Jupiter and Saturn |
|
Mars and Jupiter |
|
Mars and Earth |

Which of these is not a recognized blood type?
AO |
|
AB |
|
B |
|
O |
Blood is categorized into four different types (A, B, AB, and O) based on the type of antigens found on the outside of the red blood cells. Additionally, each type can be negative or positive based on whether or not the cells have an antigen called the Rh factor.
The heart __________ blood.
creates |
|
oxygenates |
|
filters |
|
deoxygenates |
To provide oxygen to the body, blood flows through the heart in a path formed by the right atrium → right ventricle → lungs → left atrium → left ventricle → body. When blood enters the right side of the heart it is deoxygenated. It enters the left side of the heart oxygenated after traveling to the lungs.
