The mass of a particle is 2.2x10⁻¹⁵ kg
Consider smoke particles as an ideal gas
The translational RMS speed of the smoke particles is 2.45x10⁻³ m/s.
<em>v= √3kT/m</em>
<em>where k= 1.38x10⁻²³J/K, T is 288K, and m is the mass of the smoke particle</em>
<em>2.45x10⁻³ = √3x1.38x10⁻²³x288/m</em>
<em>m= 2.2x10⁻¹⁵ kg</em>
Therefore, the mass of a particle is 2.2x10⁻¹⁵ kg.

None of the diagrams you attached shows the scenario accurately,
or at all.
Heat flows from Object-B to Object-A, until both objects are at
the same temperature, somewhere between 10°C and 29°C.
The final velocity of the pebble as it hits the ground is 21.5 m/s.
We have to use the equation;
v = u + gt
Where;
v = final velocity
u = initial velocity
g = acceleration due to gravity
t = time
Since the pebble was dropped from a height, u =0 m/s, hence,
v = gt
v = 9.8 ms-2 × 2.2 s
v = 21.5 m/s

Answer:
The subjective visual sensation related to the intensity of light emanating from a surface or from a point source.
Answer:
The force on a bullet that results from summing all of the forces on that bullet is known as the net force on the bullet.
Explanation:
Net force represents the overall force or the total force acting on an object.
Here, the object is bullet and the net force acting on it is the addition of all the forces acting on the bullet.
