The main difference is that in a gas, the atoms remain intact and generally linked into molecules, but in plasma, at least part of the electrons have completely separated from their atoms. In other words, plasma particles are charged, whereas gas particles are largely uncharged.
A change in velocity, A change in direction, or a change in both velocity and direction.
Hydrogen is a very reactive gas, and the alkali metals are even more reactive. In fact, they are the most reactive metals and, along with the elements in group 17, are the most reactive of all elements.
Answer:
A) 2.09
B) -62.09°
Explanation:
If D = A+B+C then C = D - A - B
Converting both A and B to rectangular coordinates, we get:
A = [-4.07 , 4.68] and B = [6.19 , 3.87]
Replacing these values we can get the x and y components of C:
C = [0.98 , -1.85]
Its module is:
Its angle is:
Answer: average speed
The overall rate of speed at which an object moves: calculated by dividing the total distance an object travels by the total time
instantaneous speed > The speed of an object at one instant in time.
velocity > Speed in a given direction
