<span>The normal force acting on the bag by the floor is calculated using th data on the force used to push the bag and the coefficient of friction between the bag and the floor. The normal force is determined through the formula Force / kin.coeff. Substituting, 27 N / 0.23 is equal to 117. 39 N. The answer is D.</span>

melomori [17]

Explanation:

It is known that opposite charges tend to attract each other whereas like charges tend to repel each other.

For example, when we rub a plastic pen with wool and it gets attracted towards an invisible tape then it means that there is an opposite charge present on both the objects.

A neutral object also tends to develop a charge when it comes in contact with a charged object.

Thus, we can conclude that the following statements are true.

  • The tape might be positively charged.
  • The tape might be uncharged.

Within a pendulum, as kinetic energy decreases, potential energy _____.
romanna [79]

Answer: a

Increase

Explanation:

Simple pendulum motion obeys law of conservative of energy. Where at maximum K.E, P.E = 0 and vice versa.

Also, increase in K.E will lead to decrease in P.E and vice versa.

A 12. 0 cm object is 9. 0 cm from a convex mirror that has a focal length of -4. 5 cm. What is the distance of the image from th
expeople1 [14]

A mirror equation is an equation that relates object distance and image distance to focal length. The distance of the image from the mirror will be -3 cm.

<h3>What is a mirror equation?</h3>

A mirror equation is an equation that relates object distance and image distance to focal length. It's sometimes referred to as a mirror formula.

\rm \frac{1}{v} +\frac{1}{u} =\frac{1}{f} \\\\

The given data in the problem is;

f is the focal length =  -4. 5 cm

u is the object distance=12. 0 cm

v is the image distance =?

\rm \frac{1}{v} +\frac{1}{12.} =\frac{1}{-4.5} \\\\ \rm \frac{1}{v}= \frac{1}{-3} \\\\ \rm v= -3cm

Hence the distance of the image from the mirror will be -3 cm.

To learn more about the mirror equation refer to the link;
