Velocity and displacement are fully described by both a magnitude and a direction. Velocity and displacement are which of the following?
scalar quantities |
|
combinational quantities |
|
vector quantities |
|
composite quantities |
Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction. In contrast, scalar quantities are quantities that are fully described by a magnitude only. A variable indicating a vector quantity will often be shown with an arrow symbol: \(\vec{v}\)
In the classification of life, bacteria, archaea and eukaryota are which of the following?
species |
|
domains |
|
classes |
|

Earth's breathable air is held in which atmospheric layer?
stratosphere |
|
mesosphere |
|
troposphere |
|
thermosphere |
The Earth's atmosphere has several layers starting with the troposphere which is closest in proximity to the surface. Containing most of the Earth's breathable air (oxygen and nitrogen), it's a region with warmer temperatures closer to the surface and cooler temperatures farther away which results in the rising and falling air that generates weather.
Which of the following represents the largest value?
1 mL |
|
1 kL |
|
1 cL |
|
1 ML |
Mega (M) is 106, kilo (k) is 103, centi (c) is 10-2, milli (m) is 10-3 so 1 ML represents the largest value.
