Answer:
0.285
Explanation:
Given two forces of different magnitude, it is important to note that the product of normal force and coefficient of kinetic friction should be equal to the sum of these two forces at equilibrium. Therefore, this can be Mathematically expressed as:
where N is normal force,
is coefficient of static friction, F is force and subscripts 1 and 2 represent larger and smaller magnitude forces respectively. Making the subject of the formula then
Since normal force N is also given by mg where m is mass of object and g is acceleration due to gravity then substituting N with mg we obtain that
and substituting the figures given in the question, taking g as 9.81 we obtain that
Hence,the coefficient of kinetic energy is 0.285 as calculated
Answer:
C. tiny particles called charges flowing through the wires.
Explanation:
<h3> Hello!</h3>
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
Hope it helps!
Answer:
The water does not remove the peanut butter because the peanut butter is thicker substance than the water is, therefore it would not remove immediately.. It could also be because the brown dye or color in the peanut butter color or the peanut butter itself has already gone through her clothing Dana would have to remove it as much as she could with a towel water and some soap then throw it to the washer afterward.
Hope this helps, good luck:)
