Fluorine it has a atomic radius of 42
The frictional force is 39.4 N
Explanation:
We can solve this problem by applying Newton's 2nd law of motion: in fact, the net force acting on the block is equal to the product between its mass and its acceleration. So we can write

where
is the net force
m is the mass
a is the acceleration
Here we know that the box is moving with constant velocity, so its acceleration is zero:

This means that the net force is also zero:

The net force on the block is given by the applied force, forward, and the frictional force, backward:

where
is the applied force
is the frictional force
Therefore, solving for
,

For sliced or pieces, as well as new or small potatoes, about 5-7 minutes. For whole medium-big potatoes, 10-12 minutes
The negatively charged rod cause charge migration within the penny. So, the protons and electrons in the penny move to seperate sides of the penny with the protons on the side closest to the iron ball. Then the penny could have been touched by a person or another object to ground the penny, removing the excess electrons in the penny. This is called charging by induction. So after grounding, the penny becomes positively charged. Opposite charges attract
