What is the air temperature at the tropopause over the equator?
−80°C
- The tropopause is the boundary between the troposphere and the stratosphere.
- Over the equator, the tropopause is located at a higher altitude (about 16-18 km) compared to the poles.
- The temperature at the equatorial tropopause is approximately −80°C.
- The temperature is lower because the rising warm air cools as it expands.
- The tropopause acts as a barrier, preventing significant mixing between tropospheric and stratospheric air masses.
Two balls, A and B, are thrown simultaneously, a vertically upward with a speed of 20 m/s from the ground and B vertically downward from a height of 40 m with the same speed and along the same line of motion. At what points do the two balls collide by taking acceleration due to gravity as 9.8 m/s 2?
