Chlorine needs to gain one electron and sodium needs to lose one electron
Answer:
Explanation:
Acceleration is defined as the change in velocity per unit of time
Acceleration (a) = ΔV/t
V = Velocity t = time
ΔV = V₂ - V₁ t = 11s
V₁ = 44m/s
V₂ = 66m/s
ΔV = 66 - 44
= 22m/s
Acceleration (a) = 22/11
= 2m/s²
Displacement (d): Displacement equals the original velocity multiplied by time plus one half the acceleration multiplied by the square of time.
d = v₀ + 1/2*at²
v₀ = 44m/s
a = 2m/s
t = 11s
d = 44 + 1/2*(2 x 11²)
= 44 + 121
d = 165m
Answer:
Final speed of striped ball is 3 m/s in left direction .
Explanation:
Given :
Two billiard ball with the same mass moves toward the left at the same speed 3 m/s .
Let , us assume right hand side direction to be positive and left hand side direction to be negative .
Also , let speed of ball after collision is (striped ball ) u and (solid ball) v .
It is also given that the collision is elastic .
Therefore , kinetic energy is conserved .
...... ( 1 )
Also , by conserving linear momentum .
We get :
...... ( 2 )
Putting value of u from equation 2 to equation 1 .
We get :
And , u = -3 m/s .
Therefore , final speed of striped ball is 3 m/s in left direction .
Hence , this is the required solution .
As the ship is not in motion compared with passengers on the ship so
it will be
a lighthouse on a nearby island
so correct answer will be C
