The paper clip did because it is a conductor. A pencil is made with wood and that is an insulator.
Answer: nuclear energy
Explanation: nuclear energy
A. One substance must dissolve in another
In Oder to determine the density of an object, you must measure
the object's mass and its volume.
With those two numbers in hand, the density may then be calculated,
thusly:
<em>Density = (mass) </em>divided by<em> (volume)</em>.
Answer:
D. the masses of the objects and the distance between them
Explanation:
Gravitation is a force, a force doesn't care about the shape or density of objects, only about their masses... and distances.
And you can get it using the following equation:
Where :
G is the universal gravitational constant
: G = 6.6726 x 10-11N-m2/kg2
m represent the mass of each of the two objects
d is the distance between the centers of the objects.
