What is term used for envelope of gases and water vapour surrounding planet earth

Air at 700C and 0.015 humidity ratio is cooled adiabatically by spraying water. The final temperature of the air is 550C. Specific heat capacities of dry air and water vapour are 1.005 and 1.88 kJ kg-

The first term in a sequence is 1 and the second term is 5. From the third term on each term is the average (arithmetic mean) of all preceding terms. What is the 25th term in the sequence

A blanket of gases surrounding planet is known as

If ν is the kinematic viscosity of air – water vapour mixture and DAB is the mass diffusivity of water vapour in air then the ratio v/DAB is known as

The following figure gives Mohr envelope for a rock and Mohr circle in a particular stress condition. Fracturing occurs when the Mohr circle touches the Mohr envelope at B.What is the dihedral angle

The following figure gives Mohr envelope for a rock and Mohr circle in a particular stress condition. Fracturing occurs when the Mohr circle touches the Mohr envelope at B.What type of fractures will

The escape velocity on the surface of the earth is 11.2 km/s. If mass and radius of a planet are 4 and 2 times respectively than that of earth, the escape velocity from the planet will be

If the mass of a planet is 10% less than that of the Earth and the radius 20% greater than that of the Earth, the acceleration due to gravity on the planet will be

Statement Two thirds or even more of the world's polar bears will disappear by 2050 due to shrinking summer sea ice, even under moderate projections caused by greenhouse gases in the atmosphere.Course
