False because they let it in to the atmosphere and then its condenced
10 and 40 would be your answer i believe.
solution:
Using Cartesian co-ordinate system
Final velocity =v= -4m/s
Initial velocity = u
Acceleration a = m/s²
Time (t).= 60s
By the first kinematical equation
V= u +at
U = v – at
=(-4)-(-3)(60)
176m/s
So, initial velocity was 176m/s
Polarization is the action of restricting the vibrations of a transverse wave, especially light, wholly or partially to one direction .
The second answer choice is not true (ozone is concentrated in the stratosphere, not the exosphere)
