Answer:
twice the original speed
Explanation:
the centripetal force is the force of an object moving in a circle of turning and it is given by the expression
where f = force of the object
m = mass
v = velocity
r = radius of the circle
first we need to know what the orignal speed will be then we can tell what will happen if the radius of the circle is changed to 4R.
from the expression for the centripetal force, we need to make the velocity subject of the formula
now, if the radius is changed to 4R
in the expression for v above i will need to just insert 4R in place of r
the square root of 4 is 2,
therefore
we can see that this is just twice of what the original speed was.
Answer:
In a voltaic cell, current is produced by connecting an oxidation reaction half cell to a reduction reaction half cell in an electrolyte solution. Oxidation and reduction reactions (redox reactions) are chemical reactions involving a transfer of electrons from one atom in the reaction to another. When two different oxidation or reduction reactions are connected electrically by connecting the cathode to the anode, a current is formed. The direction depends on the type of reaction taking place at the terminal.
The first step would be to determine metals to be used as the cathode and the anode.
