Question

4. The motion of gas are:-
a. 1-Dimensional
b. 2-Dimensional
c. 3 -dimensional
d. 4 dimension al
5. Magnitude of unit vector is :-
a. One
b. Two
c. infinite
d. zero​

Answer 1

Answer:

In gases the particles move rapidly in all directions, frequently colliding with each other and the side of the container. With an increase in temperature, the particles gain kinetic energy and move faster.

Answer 2

Answer:

4. 4-dimensional

explanation: in gas, the gases particles moves in all directions rapidly. The motion of gas are Often bumping against other and mailnly in the side of the container. the particles moves faster with gained the heavy kinetic energy. it happens when the increase in temperature.

5. ans. one

Explanation:

as saying by the definition of magnitude of unit vector. it has magnitude of 1.

so, if you want a unit vector in the direction of A you need to divide by its magnitude.
