Answer:
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
Explanation:
As we know that average velocity is defined as the ratio of change in position and the time interval of the object
It is given as
so we will have
= displacement
= time interval
the direction is this average velocity is always along the direction of the displacement
so correct answer will be
point in the same direction as the change in position.
require knowing the initial and final position, along with the elapsed time.
I’m almost sure it’s b , hope this helps on cripwalker
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.
Answer:
Precision
Explanation:
You can be very precise but inaccurate, as described . You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision. Precision is independent of accuracy. You can be very precise but inaccurate, as described above. You can also be accurate but imprecise. For example, if on average, your measurements for a given substance are close to the known value, but the measurements are far from each other, then you have accuracy without precision. Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise.
The force between the charges will be 10.9 N.
<h3>What is the electrostatic force?</h3>
The electrostatic attraction particles that make up the electrostatic force behave as both an attracting and a repulsive force. The force is inversely proportional to the square of the distance between them.
F ∝ 1 / r²
F = k / r²
Fr² = k
When two tiny charged objects are 0.11 of a distance apart, they repel one another with a force of 2.53. If the distance between the two particles is cut to 0.053 and the charge on each item is decreased to 67.9% of its initial amount. Then the force will be
F₁r₁² = F₂r₂²
2.53 × (0.11)² = F × (0.053)²
F = 10.9 N
