Which of the following is the formula for power?
\(P = {\vec{w} \over t}\) |
|
\(P = \vec{w}t\) |
|
\(P = {w \over t}\) |
|
\(P = w t\) |
Power is the rate at which work is performed or work per unit time: \(P = {w \over t}\) and is measured in watts (W).
An element in the physical state of __________ maintains a constant volume but their shape depends upon the shape of their container.
plasma |
|
solid |
|
liquid |
|
gas |
In the liquid state, molecules flow freely around each other and exist at a higher temperature range than the same substance in a solid state. Liquids maintain a constant volume but their shape depends upon the shape of their container.
Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s2 to a mass of 1 kg/s2 |
|
1 mph to a mass of 1 kg |
|
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.
Elements in the Periodic Table of the Elements are ordered by which of the following?
atomic weight |
|
atomic mass |
|
atomic number |
|
number of electron shells |
The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
In the heart, blood flows from the __________ ventricle to the lungs then back to the heart via the __________ atrium.
right, right |
|
right, left |
|
left, right |
|
left, left |
The two largest veins in the body, the venae cavae, pass blood to the right ventricle which pumps the blood to the lungs through the pulmonary artery. Blood picks up oxygen in the lungs and returns it to the left atrium via the pulmonary vein.
