Which of these is not a phase in cell division?
megaphase |
|
cytokinesis |
|
interphase |
|
anaphase |

50°F is how many °C?
-10 |
|
58 |
|
122 |
|
10 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (50 - 32)\)
\(C° = {5 \over 9} (18)\)
\(C° = {90 \over 9}\)
\(C° = 10\)

Velocity and displacement are fully described by both a magnitude and a direction. Velocity and displacement are which of the following?
composite quantities |
|
combinational quantities |
|
scalar quantities |
|
vector 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: \(\vec{v}\)
