Answer:
<em>Is it NOT possible for both particles to be at rest after the collision</em>
Explanation:
<u>Law Of Conservation Of Linear Momentum</u>
The total linear momentum of a system of particles is conserved regardless of their internal interactions while no external force is applied to the system. If
and
are the masses of two particles, and only one of them is at rest, there is a non-zero total linear momentum, i.e.

if at least one of the speeds is not zero, the total initial linear momentum is not zero.
If after the collision, both particles remain at rest, both speeds will be zero and the total linear momentum won't be conserved.
So, is it NOT possible for both particles to be at rest after the collision
It won't happen anything i think it will just be a something like a small thing
Answer:
18.4 s
Explanation:
The time constant of an RC circuit is given by

where
R is the resistance
C is the capacitance
For the first circuit we have


So we can find the capacitance

Now in the second circuit, the new resistance is

So the new time constant will be

Answer:
5.5 N at 50.8° north of west.
Explanation:
To find the resultant of these forces, we have to resolve each force along the x- and y-direction, then find the components of the resultant force, and then calculate the resultant force.
The three forces are:
(east)
(west)
(at 60° north of west)
Taking east as positive x-direction and north as positive y-direction, the components of the forces along the 2 directions are:



Threfore, the components of the resultant force are:

Therefore, the magnitude of the resultant force is

And the direction is:

And since the x-component is negative, it means that this angle is measured as north of west.
4 main components are: Nitrogen, Oxygen, Argon and water vapour
