Answer:
2,5
Explanation:
When move from left to right in periodic table atomic number increases. So element to the right of carbon has one electron more than carbon therefore it's electronic configuration would be 2,5
<span>Because protons are positively charged and neutrons have no charge then it is safe to say that such an atomic model would have the positive charge concentrated in the center of an atom (option d).</span>
Answer:
Forces acting on an object may be balanced or unbalanced. When the forces acting on an object have <u>equal</u> strength and act in opposite directions, they are <u>balanced</u>. These forces cancel out one another, and the <u>motion</u> of the object does not <u>change</u>. When the forces acting on an object are <u>unbalanced</u>, they do not cancel out one another. An unbalanced force acting on an object results in the object’s motion <u>changing</u>. The object may change its <u>speed</u> (speed up or slow
down), or it may change its <u>direction</u>. <u>Friction</u> is a force that resists the motion or the tendency toward motion between two objects in contact with each other. <u>Gravity</u> is a force that pulls objects toward one another. For example, Earth pulls all objects toward it.
Explanation:
Answer:
Decrease
Explanation:
Since the speed in which the gas molecules are faster as they are heated, they fly around in the container and logically, it is harder to insert a moving object into water than something more stationary or slower.
