<h2>Answer: at an angle

below the inclined plane.
</h2>
If we draw the <u>Free Body Diagram</u> for this situation (figure attached), taking into account only the gravity force in this case, we will see the weight
of the block, which is directly proportional to the gravity acceleration
:

This force is directed vertically at an angle
below the inclined plane, this means it has an X-component and a Y-component:



Therefore the correct option is c
Answer:
d.) Marbles 1 and 2 repel each other, but no interaction occurs with marble
Explanation:
Rubbing the glass against the silk charges the glass positively.
Assuming polarization is ignored,
●Glass won't conduct electrical charge. Therefore, acting as a insulator.
●neutral objects won't distribute it's charge when affected by charge objects in proximity. Therefore, over the marble surface, the charge remain spherically symmetrical (undisturbed)
Marble 1 is positive
Marble 2 is positive
Since marble 1 and 2 are positive, repulsion will occur.
marble 3 is neutral (still assuming polarization is ignored), therefore, no interaction with marble 1 and 2
D is the answer.
First, use a high-quality measurement tool. Next, measure carefully. Finally, repeat the measurement a few times. Hope it helps!
KE = 1/2 mv^2 is the relationship betwee mass and kinetic energy
The ball rolled a distance of
d = 12m + 20m.
But the change of position is
x = + 12m - 20m
