The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported.
Ionic compounds are always salts forming between a metal and a non-metal
Examples include, but are not limited to
NaCl
BaF2
Cs2O
Sometimes an ionic compound can be composed of a metal + a polyatomic ion
Examples of polyatomic ions include
Phosphate PO4 3-
Chlorate ClO3-
Some ionic compounds with these polyatomic ions include
CsClO3
Ba3(PO4)2
Hope this helps. I can’t do much good if I can’t see the options.
The arrows around the positive point charge illustrates the direction of the electric force/field.
<h3>What is Electric field?</h3>
This is described as an area in which force is exerted om other charged particles or objects.
Arrows could be around the positive or negative point charge and helps to depict the direction of the electric force.

constant voltage of 100 volts and a resistance of 500 ohms.
<span>I = 100 / 500. Current = 0.2 amps </span>
<span> resistance to 200 ohms. I = 100 / 200. Now the current is 0.5 amps.</span>
As we also know that Voltage is directly proportional to the current
Resistance is the proportionality constant.
Answer:
1)X(t)=Xo±Vo(t)±*a
2)a(t)=
Explanation:
1)with this formula you can determine the position of the object studied when you have an accelerated, or deaccelerated motion, where Xo its your beginning position, and Vo is your beginning speed, and t is the difference of time between the final time and the initial time. The signs of the equation (+ or -) depends if its displacement its increasing on time, or diminishing, it means : positive speed, and acceleration, and in the oposite case negative speed and acceleration respectively.
2)this formula lets you know the variation of speed at each time (considering its constant), so if you have a constant variation of speed along a determined time, then you can use it.
This formula is used in uniformly accelerated rectilinear motion
