The answer is B.) Able to travel through a vacuum!! <3
Answer:
A force is a push or a pull. It causes an object at rest to move. It can cause an object that is moving to change speed, or the distance covered over time. It can also change which way the object is moving its direction. Lastly, it can also cause an object to stop moving completely. A force has both magnitude and direction. An object with balance forces or a net force of zero will not change position.
Explanation:
Along with neurons, the nervous system contains other specialized cells called glial cells (or simply glia), which provide structural and metabolic support. Nervous systems are found in most multicellular animals, but vary greatly in complexity.
Answer:True
Explanation:
When we rub a glass rod with silk cloth electrons of glass rod are stripped away by the silk cloth making glass rod Positively charged i.e. relatively glass rod has more positive charge than negative charge.
During this Process no charge is created but transfer of the charges makes the rod relatively Positive and silk cloth relatively negative.
Thus net charge is same and no new charge is created.

<h2>Archimedes' principle</h2>
''states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially, is equal to the weight of the fluid that the body displaces.''
Archimedes principle equation is given as
buoyant force = density of fluid x volume of displaced fluid x acceleration due to gravity. or
<em>Fb=-density*gravity*volume </em>
<em>For example,</em> a ship that is launched sinks into the ocean until the weight of the water it displaces is just equal to its own weight.
