Initial velocity (u) = 2 m/s
Acceleration (a) = 10 m/s^2
Time taken (t) = 4 s
Let the final velocity be v.
By using the equation,
v = u + at, we get
or, v = 2 + 10 × 4
or, v = 2 + 40
or, v = 42
The final velocity is 42 m/s.
Answer:
hold on let me check my answer
Explanation:
Of biogeochemical cycles
Because certain biogeochemical cycles take place to lessen these gases from forming since they are not beneficial for life if too much.

Angle made by the light ray with the surface of mirror is given as
degree
now as we know as per law of reflection that
angle of incidence = angle of reflection
So here we can say that


now the total angle that reflected ray will rotate with respect to incident ray is known as angle of deviation


so here reflected light will deviate by total angle of 40 degree fron its incident ray.
