Answer:
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior.
Explanation:
Very unlikely. This is not really a good question for Brainly.
A control variable is the one element that is not changed throughout an experiment.A dependent variable is a variable whose variation does not depend on that of another.A independent variable is a variable whose value depends on that of another.
Answer is E
time can be negative.
A is not true because <span>a=<span><span><span>d2</span>x</span><span>d<span>t2</span></span></span>=12 m/<span>s2</span></span>
C: question already said that particle move along x-axis, which is not parabola path.
D: velocity is <span><span><span>dx</span><span>dt</span></span>=12t</span>, therefore velocity changes by 12 m/s and not 9.8 m/s
So we are left with E.

<span>So are strong bases. The reason acids and bases conduct electricity is that when they are mixed with water, they "separate" into ions. And the ions are charge carriers. These charge carriers can be made to carry a charge (which is why that description fits them).</span>
