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.
Answer:
Explanation:
For example, an ice cube has heat energy and so does a glass of lemonade. If you put the ice in the lemonade, the lemonade (which is warmer) will transfer some of its heat energy to the ice.
Answer:
18.9 <em>N or </em><em>19</em><em> N </em>rounded
Explanation:
m = 0.145 kg
a = 130 m/s^2
F = ma = (0.145 kg)(130 m/s^2) = 18.9 <em>N</em>
this is simple the word your looking for is 8 letters long and the definition is key to the answer
