Which of the following is not a vector quantity?
acceleration |
|
velocity |
|
momentum |
|
mass |
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: \(\vec{v}\)
The coldest point in the Earth's atmosphere is reached in which atmospheric layer?
troposphere |
|
mesosphere |
|
thermosphere |
|
stratosphere |
In the mesosphere, temperature again drops as altitude increases until the coldest point in the Earth's atmosphere, the mesopause, is reached where temperatures fall to −225 °F (−143 °C).
