The atmosphere at this level of altitude is called Heterospher
80 Kms to 480 Kms
80 Kms to 580 Kms
180 Kms to 480 Kms
From the surface of the earth to 80Kms
To what extent the atmosphere is extended above the surface of the Earth, assuming the density of air to be uniform [1.3 kg/m3] and pressure at the surface of Earth to be 105 Pa. (Also assume the Earth to be perfectly spherical and no variation in 'g' due to height.)
The region of Earth's upper atmosphere that extends from about 60 km (37 mi) to 1,000 km (620 mi) altitude is called __________.
A car moves for half of the total time of travel at 80 km/h and for rest half of the time at 40 km/h.
If the total distance covered is 60 km, what is the average speed of the car?
