Answer:
c. turn downward
Explanation:
From the information given:
To find the tendency of the sander;
We need to apply the right-hand rule torque; whereby we consider the direction of the flywheel, the direction at which the torque is acting, and the movement of the sander toward the right.
Since the flywheel of the sander is in counterclockwise movement, hence the torque direction will be outward placing on the wall. However, provided that the movement of the sander is toward the right, then there exists an opposite force that turns downward which showcases the tendency in the sander is downward.
A single electron has a charge of
Therefore, if we have an excess of
electrons, the total net charge will be the product between the charge of a single electron and the total number of electrons in excess:
Answer:
For a plant cell: The cell wall and the cell membrane
For animal cells: Just the cell membrane
