|
rain |
|
snow or ice |
|
ice |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.

ventricle, atrium |
|
atrium, ventricle |
|
atrium, atrium |
|
ventricle, ventricle |
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.
Acceleration is the rate of change of velocity per unit of time. Which of these is the formula for acceleration?
\(\vec{a} = { t \over \Delta \vec{v} }\) |
|
\(\vec{a} = { \vec{v} \over t }\) |
|
\(\vec{a} = \Delta \vec{v} t \) |
|
\(\vec{a} = { \Delta \vec{v} \over t }\) |
Acceleration is the rate of change of velocity per unit of time. In physics, the delta symbol (\(\Delta\)) represents change so the formula for acceleration becomes \(\vec{a} = { \Delta \vec{v} \over t }\)
