Answer:
<h3><em><u>Magnesium has an atomic number of 12, which means its neutral atom has 12 electrons. The Mg2+ ion is formed when the neutral magnesium atom loses 2 electrons, which brings its total number of electrons to 10</u></em></h3>
Answer:
V = E*d
D = 1.5 cm * [1 m / 100 cm] = 0.015m
V = 2.9^10^6 N/C * 0.015 m
V = 1.93 * 10^9 V
The units don't agree in any simple way, but the formula is correct, and it does work.
Explanation:
Answer: Negative acceleration occurs when an object slows down in the positive direction.
Positive acceleration occurs when an object speeds up in the positive direction.
Explanation: Acceleration can be positive or negative. A negative acceleration is also known as deceleration. And deceleration occurs when an object is coming to rest. While acceleration simply means that an object is Speeding up.
Negative acceleration occurs when an object slows down in the positive direction.
Positive acceleration occurs when an object speeds up in the positive direction.
ALL of the quantities are unknown, because you haven't bothered to tell us anything that's known.
