May I see the Sunspot Activity chart next to it?
Answer:
acceleration: 5 mi/h/s north
Explanation:
A quantity can be either vector quantity or scalar quantity, a vector quantity is a quantity with both magnitude and direction while a scalar quantity has magnitude only.
Examples of vector quantities include; velocity, acceleration, displacement , etc.
Acceleration is the rate of change of an object's velocity per unit of time. It is given by the formula; Velocity/time
Therefore in this case; a = 30 mi/h /6 s
= 5 mi/h/s
Therefore;
Acceleration = 5 mi/h/s
Channel proteins
Channel proteins are macromolecules that are embedded in plasma membranes of cells. Their function is to provide a pathway for molecules into and out of the cell, as the remaining parts of the membrane are impermeable. An example of such protein channels are those that are present to facilitate the diffusion of glucose.
